How do you fix a Mercedes ESP malfunction?
How do you reset the ESP® BAS light on a Mercedes-Benz? – If your Mercedes-Benz ESP® BAS light is on, it means one or more related systems have an issue. Sometimes it can come on after a battery replacement, in which case resetting it is simple. Start your vehicle, and while parked, turn the steering wheel as far as it can go to the right, then do the same but to the left.

What causes ESP failure?
EPS system failures – EPS is a reliable car element, still failures happen, and it affects the safety. That is why, in case of system failure it must be repaired. EPS sudden failure can be unnoticed by the driver. This happens when error display is not provided. Carrying out of a simple test can help to diagnose the EPS system condition:
Stop the engine and turn the wheel;Start the engine and turn the wheel again.
Compare both effects: when it takes a big effort to turn the wheel in both cases, further diagnostics is strongly required. It happens sometimes that EPS stops to operate when a speedometer is off. In this case, the most possible reason of failure is the trouble with a speed sensor engaged with both speedometer and power steering.
The speed sensor itself can be damaged, and thus, the substitution of the sensor or the wire is required. EPS repair is needed in case of voltage drop. Undervoltage can as well lead to EPS outage, while in case of overvoltage a surge-voltage protector is included. EPS outage can be caused by a car battery, an alternator or a circuit fault.
Regular checkup should be provided for all those car elements.

Can you drive with faulty ESP?
Constant illuminated ESP light – A constant illuminated ESP light indicates the system is inoperative – either because you have switched it off (usually by pressing and holding a button with the matching symbol) or because there is a fault with the system.
Even when you do switch the system off in some cars – most Volkswagens for example – it’s not actually off, the parameters within which it operates have simply been loosened to free up more corner performance on track, say. On other cars, the system turns off when you select particular driving modes – so you don’t have to press the ESP button.
A faulty ESP system doesn’t make your car dangerous per se, but if your car’s fitted with such an effective safety system it would be mad not to have it fully operational. Even professional driving instructors keep the system engaged on the road. ESP is important in a car.
It’s a proven safety device that’s reassuring to have if you’ll be using your car to ferry about your family and loved ones. There are very rare examples when it doesn’t make sense, though, for example, if you’ll purely use your car on track it could restrict its performance. As a general rule when driving on the road, there are many positives to having ESP on and no negatives.
Yes, it is safe to drive with ESP light on but we wouldn’t recommend it? If your ESP light is on it means you’ve switched it off or there’s a fault with the system and it’s not operating correctly. As a result, it won’t be able to stop your spinning like it would do if it was operational.
While not necessarily dangerous, it does mean an important safety feature isn’t working, it’s prudent to get it fixed if there’s a fault and we’d advise keeping the system switched on. When the ESP light comes on in your car it could mean one of two things. If it flickers, your car’s ESP has had reason to activate likely due to a sudden manoeuvre or quick cornering.
If the light stays solidly on, it means there’s a fault with the system and you should have it looked ASAP.

How do you reset the traction control on a Mercedes?
How to Reset a Traction Control Light (TCS): Causes and More
- Use an on-board diagnostic (OBD2) scan tool to reset your TCS/ABS light by plugging it into the diagnostic link connector (DLC) and clearing the code.
- Driving your vehicle for a few minutes after reconnecting or installing a new battery may get the light to turn off.
- If the TCS light comes back on after you’ve reset it, take your vehicle to the mechanic.
- The traction control system keeps your vehicle from sliding. The traction control system (TCS) identifies when one (or more) of your wheels loses its grip on the road. When this happens, the TCS light starts blinking as it automatically applies the brakes to the tire(s) that have lost their grip so that you can regain control.
- This system is tied to your anti-lock braking system (ABS), which controls your brakes and helps them keep your vehicle stable in high-braking situations. This is why a TCS light is often accompanied by the ABS light.
Advertisement
- 1 The traction control system is off You probably already checked this one, but on the off chance you don’t know, you can turn the TCS system on and off. Just click the TCS button once to see if the light goes away—you may have accidentally turned the system off.
- The TCS system is always on unless you turn it off.
- The TCS button usually has a car with swerving lines coming out of the tires on it. The word “off” is usually printed on the button as well.
- Refer to your manual to find the TCS button in your specific vehicle. It’s usually either on your turn signal, or the bottom half of your dashboard controls.
- 2 Bad road conditions If your TCS or ABS light pops on when you’re driving in the snow or rain, your vehicle is letting you know that your TCS/ABS system is engaged. Slow down a bit to maintain better control of your vehicle and the light should go away. Advertisement
- 3 Wiring damage There are wires that run from each wheel’s speed sensor to your vehicle’s main computer. If these wires are corroded or damaged, your vehicle will think the wheels aren’t turning at the same speed, which causes the traction control to engage. Getting these wires replaced will solve your problem.
- If you’re a gearhead who loves working on vehicles, throw your car up on jacks, disassemble the wheels, and inspect the cables running to the wheel sensors. Wrap any exposed wires in electrical tape to see if that solves your problem.
- 4 Faulty wheel speed sensors If the wires aren’t damaged, the sensors themselves may be to blame. When you speed up or slow down, the wheel sensors send a signal to your vehicle to let them know the speed is changing. If those reported speeds don’t match, the TCS kicks in. Getting the sensors replaced can solve this.
- The older a vehicle gets, the more likely these sensors are to fail over time.
- This is not a DIY repair job, since it involves calibrating and wiring a delicate sensor. Take your vehicle to a mechanic to get these sensors replaced.
- 5 Antilock braking system malfunctions The traction control system works alongside the anti-lock brake system to automatically keep your vehicle stable. They’re both controlled by the same cables and sensors, so if your ABS system fails or ends up out of whack, it can cause your traction control system to also malfunction.
- Have a mechanic take a look if your ABS and TCS lights are on. It can be extremely difficult for a non-professional to identify which system is at fault here.
- 6 Bad steering rack If you’ve got other warning lights popping up beside the ABS and TCS lights, your steering wheel feels clunky, or your vehicle feels like it’s accelerating slower than it should be, your steering rack is probably damaged. Take the vehicle to a mechanic to have them inspect and repair your steering rack.
- The steering rack is a delicate, essential part of your vehicle. Have a professional replace or repair the steering rack.
- Your check engine light should also pop on if you’ve got a damaged steering rack.
- 7 New battery It’s normal for the traction control light to pop on after you’ve replaced the battery. Keep driving your vehicle for a few minutes. The light should turn off on its own once your vehicle’s computer fully resets.
- 8 Computer programming errors This is where resetting your traction control system is likely to solve the problem. A system error or glitch can easily throw off your TCS system settings and cause the light on your dashboard to pop on.
- To reset your vehicle’s computer, turn your vehicle off and find the fuse box. Remove the fuses labeled “back up” and “ECU.” Leave the fuses out for 10 minutes before reinstalling them. Put the cover back on and go for a quick test drive.

- 1 Purchase or rent an, If you perform even minor repairs on your vehicle, an OBD2 scanner is a great investment. You can purchase one online or at a local automotive repair store. Alternatively, you could rent one from an auto supply store. An OBD2 scanner plugs into your vehicle and scans the vehicle’s systems for errors and fault codes, and you can use one to reset your TCS/ABS lights.
- The really nice OBD2 scanners will run you a few hundred dollars, but you can buy a cheaper model for $30-50.
- If your vehicle was made before 1996, you’ll need an original OBD device, not an OBD2. The OBD2 will work on any vehicle made after 1996, though.
- 2 Plug it into your dashboard’s Diagnostic Link Connector (DLC). Consult your vehicle’s manual to find where the connection port is for your OBD2 device. In almost every vehicle, it will be located under the steering wheel—usually on the left side. You may have to peel a panel off of your dashboard to access it, although many cars just have a cover on it. Plug the OBD2 directly into the DLC port.
- 3 Erase and reset your dashboard lights with an OBD2 scanner. Power the OBD2 on. Enter your vehicle’s make and model. Then, select “systems” or “control unit” to pull up the different vehicle systems. Find your TCS/ABS system and select “erase codes” or “reset codes” to clear the warning light and reset your TCS system.
- You can use the “auto scan” function to automatically search your vehicle and pull up any issues or problems.
- Depending on your OBD2 device, you may need to using the key that came with the model.

- 1 Toyota Toyota doesn’t have a dedicated traction control light—their vehicles combine the ABS and TCS systems into a single VCS (vehicle control stability) system. Put your car in park. Press and hold the VSC button for 5 seconds and the TRAC OFF and VSC OFF lights should both come on. Press the VSC button one more time and your traction control system will reset.
- Refer to your manual to identify the location of the VCS button. In most models, it’s next to your gear shift.
- If the lights don’t go off, take your vehicle to a mechanic.
- 2 GM Turn the key into the on position without starting the engine. Then, tap your gas pedal 3 times in quick succession. Now, start your engine. This may reset your vehicle’s diagnostic computer and reset the TCS and ABS systems.
- GM does not offer an “official” method for resetting GMC, Buick, Chevrolet, Chevy, or Cadillac traction control lights, and their manuals all suggest taking your vehicle to a mechanic to have the underlying problem diagnosed and fixed.
- If your lights come back on, see a professional to get help diagnosing the problem.
- 3 Ford/Lincoln Ford calls their traction control system “AdvanceTrac.” If your AdvanceTrac light comes on, turn the car on and pop the hood., Let the vehicle run for 5 minutes and then reconnect the battery and restart your car.
- If your AdvanceTrac light comes back on, go see a mechanic.
- In theory, if your alternator works, removing the negative terminal should not harm your vehicle. However, there is an off chance that this damages your vehicle’s computer if your vehicle isn’t in tip-top shape.
- 4 Hyundai-Kia Put the key in the ignition and turn it to the on position without starting the vehicle. Press the gas pedal 3 times in quick succession. Then, turn your engine on all the way and let it run for a minute. The TCS and ABS lights should reset and go away if there isn’t any underlying problem with your traction control system.
- On some Hyundai and Kia models, the TCS and ABS systems are combined into a single ESC (electronic stability control) system.
- Take your vehicle to a mechanic if the ESC, TCS, or ABS light comes back on.
- 5 Honda/Acura Remove the panel under the steering column and find the OBD connector, which is a 16-pin port. Turn the key in the ignition to the “on” position and press the gas pedal with the engine off. Unravel a paper clip and put one end into the top right opening, and the other end into the fourth from the left on the bottom. Release the brake pedal and let the ABS/TCS lights blink repeatedly.
- After you let the light blink for a minute, turn the ignition to the off position and remove the paper clip. The ABS/TCS light should reset the next time you start the car.
- The paper clip in the OBD connector solution may seem strange, but the TCS and ABS lights pop on in Hondas and Acuras when the battery’s voltage is low. The paper clip clears the low voltage signal to your computer and forces it to accurately read the wheel sensors.
- If the ABS/TCS comes back on, take your vehicle to the mechanic.
- 6 Volksagen/Audi Volkswagen and Audi combine the TCS and ABS systems into a single EPC (electronic power control) system. If your EPC light pops on, try resetting it by starting your car normally in park. Let the vehicle run for a minute and then turn the vehicle off. Then, restart the car except this time, push the gas pedal to the floor for 1-2 seconds while the engine starts.
- If the EPC light comes back on while you’re driving, take it to a mechanic.
- 7 Tesla With the vehicle on, hold down both scroll wheels on the steering wheel until the display turns off. Wait for your unit to restart, which should take 2-3 minutes, and your TCS warning signal should disappear. If it doesn’t, go into the Controls menu, select Safety & Security, and then tap the Power Off button. Your Tesla will perform a full reboot and recheck all of its electrical systems.
- If the warning signal comes back, take your Tesla to a Tesla dealership to have it inspected.

Can I turn the ESP off?
You shouldn’t turn the ESP off – In many cars the traction control system (TCS) or even the entire electronic stability program can be switched off. However, this feature should only be used in a few exceptional cases, as the ESP provides greater driving safety and prevents a large number of accidents.
Especially in winter, the TCS and the ESP have an important function, as they can prevent or reduce the breaking of the vehicle even on wet, snowy and slippery roads. Nevertheless, there are situations where a short-term deactivation of the system can be beneficial. An example for such a situation is driving on a snow-covered road in winter.
The ESP can lower the engine power when the wheels are spinning. Therefore the vehicle can use the necessary momentum to drive or start driving in the snow and worst case you could get stuck in the snow. Before you turn the ESP off, you should first do some tests on how driving without the stability program feels like.

What is ESP malfunction?
What to do if your ESP light comes on? Modern cars have many separate systems running in unison that not only improve the efficiency of the vehicle but also make them a lot safer to drive than their predecessors. One of these systems is the ESP, which kicks in when the car senses that an extreme steering manoeuvre is taking place.
You should notice the light comes on under these circumstances, but it can also come on or start flashing during regular driving. This generally indicates that there is an issue with the vehicle that is linked to the ESP, from one of the sensors malfunctioning to a major component not working properly.
Below we have a look at what the ESP is, how it works and what the potential issues are if the light comes up on your dashboard.

How do I turn off the ESP light in my car?
How do I turn off the ESP BAS light in my Jeep? The ESP BAS warning light is displaying on my dash. I lost my owner’s manual and have been troubleshooting how to turn off the light but can’t seem to figure it out. How can I turn off the ESP BAS light in my Jeep Wrangler? Oh no! Losing your manual is never ideal, particularly when a warning light presents itself in your car.
- No need to worry, you’ve come to the right place.
- The ESP BAS light indicates that your Jeep’s Electronic Stability Program (ESP) or your Brake Assist Program (BAS) aren’t functioning as they should.
- These systems are vital to the safety of your vehicle and any problems should be addressed as soon as possible.
When the ESP BAS light comes on, your vehicle is telling you that a sensor needs to be replaced or reset. Most commonly, the Steering Angle Sensor needs recalibration. As such, to turn off the ESP BAS light, you will need to reset the steering angle sensor,
Simply turn the steering wheel twice to the right, twice to the left, and back to the center, Your steering angle system will be recalibrated and the ESP BAS light should turn off. If the light does not turn off after performing the steering angle recalibration, you may have a problem with your Wheel Speed Sensor,
In this case, you can replace the malfunctioning sensor with a new one, which should turn off the ESP BAS light and allow your Wrangler to drive as normal.

How do you clean an ESP sensor?
Cleaning the ABS Sensor – 
Photo by Wild Out White GSR With the sensor free, take your rag and wipe the sensor until it’s clean. I prefer not to use any chemicals on the sensor to avoid potential problems. If, however, the sensor is really grungy, use a mild soapy solution and rinse well.
- The ABS sensors are precision instruments in a crude environment.
- They’re tough enough to hang off the brakes of a fast-moving vehicle, but one good knock and they could be damaged beyond repair.
- Eep this in mind when working with these sensors.
- A little care taken now will save you a costly repair later.
To finish the job, reinstall the sensor in exactly the same manner as you removed it. Don’t skip the step of reattaching the line or wiring to those mounting points. They may seem like they don’t matter, but it can get very expensive if you make a bad decision.

- If the warning signal comes back, take your Tesla to a Tesla dealership to have it inspected.

- If resetting the light doesn’t work, get some professional help. The ABS and TCS systems are essential when it comes to staying safe on the road—especially when it’s raining or snowing. If resetting the light doesn’t help, take the vehicle to a professional to have the underlying problem diagnosed and fixed.
- You can still drive with the TCS light on, but you should go slower than you normally would and avoid driving in harsh conditions.

What does ESP malfunction mean?
What to do if your ESP light comes on? Modern cars have many separate systems running in unison that not only improve the efficiency of the vehicle but also make them a lot safer to drive than their predecessors. One of these systems is the ESP, which kicks in when the car senses that an extreme steering manoeuvre is taking place.
- You should notice the light comes on under these circumstances, but it can also come on or start flashing during regular driving.
- This generally indicates that there is an issue with the vehicle that is linked to the ESP, from one of the sensors malfunctioning to a major component not working properly.
Below we have a look at what the ESP is, how it works and what the potential issues are if the light comes up on your dashboard.

How do you turn off the ESP?
How do I turn off the ESP BAS light in my Jeep? The ESP BAS warning light is displaying on my dash. I lost my owner’s manual and have been troubleshooting how to turn off the light but can’t seem to figure it out. How can I turn off the ESP BAS light in my Jeep Wrangler? Oh no! Losing your manual is never ideal, particularly when a warning light presents itself in your car.
No need to worry, you’ve come to the right place. The ESP BAS light indicates that your Jeep’s Electronic Stability Program (ESP) or your Brake Assist Program (BAS) aren’t functioning as they should. These systems are vital to the safety of your vehicle and any problems should be addressed as soon as possible.
When the ESP BAS light comes on, your vehicle is telling you that a sensor needs to be replaced or reset. Most commonly, the Steering Angle Sensor needs recalibration. As such, to turn off the ESP BAS light, you will need to reset the steering angle sensor,
Simply turn the steering wheel twice to the right, twice to the left, and back to the center, Your steering angle system will be recalibrated and the ESP BAS light should turn off. If the light does not turn off after performing the steering angle recalibration, you may have a problem with your Wheel Speed Sensor,
In this case, you can replace the malfunctioning sensor with a new one, which should turn off the ESP BAS light and allow your Wrangler to drive as normal.

Can you drive with faulty ESP?
Constant illuminated ESP light – A constant illuminated ESP light indicates the system is inoperative – either because you have switched it off (usually by pressing and holding a button with the matching symbol) or because there is a fault with the system.
- Even when you do switch the system off in some cars – most Volkswagens for example – it’s not actually off, the parameters within which it operates have simply been loosened to free up more corner performance on track, say.
- On other cars, the system turns off when you select particular driving modes – so you don’t have to press the ESP button.
A faulty ESP system doesn’t make your car dangerous per se, but if your car’s fitted with such an effective safety system it would be mad not to have it fully operational. Even professional driving instructors keep the system engaged on the road. ESP is important in a car.
It’s a proven safety device that’s reassuring to have if you’ll be using your car to ferry about your family and loved ones. There are very rare examples when it doesn’t make sense, though, for example, if you’ll purely use your car on track it could restrict its performance. As a general rule when driving on the road, there are many positives to having ESP on and no negatives.
Yes, it is safe to drive with ESP light on but we wouldn’t recommend it? If your ESP light is on it means you’ve switched it off or there’s a fault with the system and it’s not operating correctly. As a result, it won’t be able to stop your spinning like it would do if it was operational.
- While not necessarily dangerous, it does mean an important safety feature isn’t working, it’s prudent to get it fixed if there’s a fault and we’d advise keeping the system switched on.
- When the ESP light comes on in your car it could mean one of two things.
- If it flickers, your car’s ESP has had reason to activate likely due to a sudden manoeuvre or quick cornering.
If the light stays solidly on, it means there’s a fault with the system and you should have it looked ASAP.
