SOURCE: BAS (Brake Assist System)

I also have a C240 (2000 model) and I also have the BAS malfunction notice appear for my car. I called an RAC engineer to carry out a Diagnostics on my car and the BAS malfunction did not appear on his laptop. He said even if it did, only a MERC dealer service centre could reset the fault as it was a 'brake' issue and only they were allowed. My car does not brake any less or feel any less safe braking or driving, thus I feel the fault is a 'bug'. I hope to go to MERC and get the fault reset because it is becoming a pain as it is the only one showing on my dash!

The esp bas light is on my 2009 dodge 1500 and it won't start


An Electronic Stability Program (ESP)/Brake Assist System (BAS) indicator is standard equipment on all instrument clusters. The ESP/BAS indicator is serviced as a unit with the instrument cluster.
The ESP/BAS indicator gives an indication to the vehicle operator when the Electronic Stability Program (ESP)/Brake Assist System (BAS) has been activated. This indicator is controlled by a transistor on the instrument cluster circuit board based upon cluster programming and electronic messages received by the cluster from the Controller Antilock Brake (CAB) and the Transmission Control Module (TCM) over the Controller Area Network (CAN) data bus.
The ESP/BAS indicator Light Emitting Diode (LED) is completely controlled by the instrument cluster logic circuit, and that logic will only allow this indicator to operate when the instrument cluster receives a battery current input on the fused ignition switch output (run-start) circuit. Therefore, the LED will always be OFF when the ignition switch is in any position except ON or START. The LED only illuminates when it is provided a path to ground by the instrument cluster transistor. The instrument cluster will turn ON the ESP/BAS indicator for the following reasons:
  1. Bulb Test- Each time the ignition switch is turned to the ON position the ESP/BAS indicator is illuminated for about four seconds as a bulb test.
  2. ESP/BAS Indicator Lamp-On Message- Each time the cluster receives an electronic ESP/BAS indicator lamp-ON message from the CAB indicating that the ESP/BAS system has been activated, the ESP/BAS indicator will be illuminated. The indicator remains illuminated until the cluster receives a lamp-OFF message from the CAB, or until the ignition switch is turned to the OFF position, whichever occurs first.
  3. ESP Full Off Textual Message- Each time the cluster receives an electronic ESP Full OFF indicator lamp-ON message from the CAB indicating that the ESP/BAS system has been manually disabled, an ESP OFF textual message will appear within the cluster odometer display. The ESP OFF textual message remains displayed until the cluster receives a lamp-OFF message from the CAB, or until the ignition switch is turned to the OFF position, whichever occurs first.
  4. Actuator Test- Each time the cluster is put through the actuator test, the ESP/BAS indicator will be turned ON, then OFF again during the bulb check portion of the test to confirm the functionality of the LED and the cluster control circuitry.
The CAB continually monitors the ESP/BAS circuits and sensors to decide whether the system is in good operating condition and the proper outputs to the components of the system. The CAB then sends the proper lamp-ON or lamp-OFF message to the Electro Mechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN).
For proper diagnosis of the ESP/BAS system, the CAB, the TCM, the EMIC, the CAN data bus or the electronic communication related to the ESP/BAS indicator operation a diagnostic scan tool is required. Refer to the appropriate diagnostic information.

I have a 2000 Mercedes E430 base sedan. Last week I replaced the brake light switch because it was out and it solved the problem to the point that I can now put my car into gear and drive it, however, as...


Brake light switch problem may cause the ESP / BAS lights to illuminate.

Common symptoms of a bad
Mercedes brake light switch.
  • Car stuck in Park.
  • ABS ESP ETS lights come on.
  • Can not move the shifter from Park to Drive.
  • Brakes Defective Warning on Instrument Cluster
  • Car won't shift gears. Stuck in 2nd gear, limp mode.
  • Brake lights don't work. (Brake light switch can still be defective even if the brake lights work. Checking the brake light operation is not a good test.)
  • ESP, BAS, ABS lights turn on. Car won't shift properly. Stuck in gear.


TEST: To test your new brake light switch: Turn you car off to reset the ABS light. apply the parking brake. and start the car in neutral or park without using the brake. if the problem is the brake light switch... the light will only come on when you press the brake pedal.

If you replaced the brake light switch and the light is still on you should check a few other things such as:

  • Fuses and Relays
  • ABS pump
  • ABS wheel speed sensor
  • Brake Fluid Level
  • Get an advanced scanner to read trouble codes.


NOTE: ** You may need a MBZ scan tool to reset the error code which was stored in the ECU because of the bad brake light switch.

Esp warning light and bas on


Hi there:
The BAS/ESP lights pertain to your brake assist and electronic stability systems. One of the more common problems we find is a faulty stop light switch or a steering angle sensor. It would be a good idea to have the fault codes read. The codes would give you a pretty good idea as to what is going on. You could try to initialize the steering angle sensor first. This is normally needed after a dead or weak battery condition. To do this you'll need to start the car and then turn the wheel slowly all the way to the left, pause and then turn slowly all the way to the right, pause and return to center. You may need to do it a couple of times to initialize the sensor. The stop light switches are inexpensive and easily replaced. They're located under the dash at the brake pedal. When you get your new switch you'll see a little release tab on it. You just depress the tab and rotate the switch 90 degrees to remove it.


Before to replace some parts, I suggest scaned the computer car in order to know other fault codes stored.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day

BAS/ ESP light on the dash bord stays on all time the car engine is running


The BAS stands for Brake Assist System, don't remember what ESP stands for.
But the first thing to do is make sure the brake lights go on when you hit the pedal.
If not, then replace the brake light switch above the pedal.
If that is not it, it could be many things, such as a bad lateral acceleration switch.
