SOURCE: Warning Light on Mercedes ML270

Hi,

To my understanding:
BAS ESP - Electronic Stability Program (keeps you moving in the direction you intended the vehicle to go); probably a faulty brake switch or a bad brake sensor. You may want to reference this forum for additional insights;
ETS - Electronic Traction System (keeps you moving); would require an appropriate code reader to diagnose and pinpoint problem.Surprisingly, there has been some reports of defective brake pedal switch that activates this warning. You may lilkewise want to reference this forum for additional insights.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

SOURCE: I have two orange warning lights on the dash- BAS

My Benz did the same and the cruise control would cut after a short period of time. If this is also happening to you,you need a Brake safety switch replaced.This is located behind you brake pedal.Go by a local Mercedes mechanic they should have one it's a common problem. You can put it on your self if you can screw in a light bulb! The warning lights will reset after a few engine starts.

SOURCE: ESP/BAS warning light on. went

Hi, these systems are all linked together. Most commonly, one of the wheel speed sensors is not reading or is reading incorrectly. This can also occur on slippery surfaces where one or more wheel slides enough to cause the sensor to drop the signal, but not enough to meet criteria for an abs or esp episode. If the light comes back every time you turn on the ignition, there is a deeper problem.
The system has detected a fault in the electronic stability program - brake assist system. You have an electrical connection at the rear wheels secured to the inside of the brake area and are viewable from under the vehicle. It is a small wire harness running to each wheel. Grab the connector and wiggle it around, and make sure they are tight. Due to the connector being mounted low to the ground, sometimes they become dirty or corroded, not making contact. Do this on both sides and see if the lights turn off.

If the light does not turn off, you have to replace dynamics sensor, which is mounted UNDERNEATH the center console in the car. There is a "lost communication to dynamics sensor" and "low voltage to dynamics sensor supply"..

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.

BAS/ESP indicator lights remain illuminated


Maybe a wheel sensor issue.
Charge battery fully - an under performing battery can create gremlins.

I have an 06 Dodge Magnum. ESP/BAS light


Whenever this warning or any other stays on in the dash it id indicating that the systems control module has detected a fault, it then disables the system as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

What does it mean when your engine light, esp and bas light comes on


ESP = electronic stabilitly program, BAS = brake assist system. There could be a number of issues causing these lights to come on. Loose sensor connector at one or more wheel locations. Build up of dirt and grim on the sensor or sensor wheel can also cause these lights to come on, These are the two easiest thoings you can do, otherwise, a service call will need to be made at your local Jeep dealer due to the complexity of this system.

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.
