Possible causes

  • Re-Initialize Steering Angle Sensor
  • Tech notes

    1. Determine whether ESP MK25 system is installed in vehicle. You can recognize externally whether the new ESP MK25 system or the old ESP MK20 system is installed by proceeding as follows:
    In individual cases, it is possible for the ETC control module with part number 030 545 23 32 (EGS 52 Q01 or SW 14/01) to send erroneous data on the CAN-C bus after switching on the ignition
    - One pressure sensor on master brake cylinder: ESP MK25 (new)
    - Two pressure sensors on master brake cylinder: ESP MK20 (old)
    A further recognition characteristic on the MK25 system is the new combined yaw rate/lateral acceleration sensor. The electronic stability program (ESP) receives this data and then erroneously assumes that the steering angle sensor signal came from the steering tube module rather than the combined yaw rate/lateral acceleration sensor, However, since the steering tube module is not currently installed in model 203, the ESP control module does not receive any data and stores the DTC specified in the document. Conversion from MK20 to MK25 was accomplished on approx. 08/2001, however, some preliminary vehicles were produced It is therefore important to differentiate on the basis of the number of pressure sensors present on the master brake cylinder.

    2. Remove/install/replace ETC control module

  • C1170 Mercedes-benz Description

    The Electronic Stability Program (ESP) is an active safety system which improves vehicle stability in all driving situations.

    It operates by actuating the brakes individually on one or more wheels on the front or rear axle. ESP stabilizes the vehicle when cornering, when braking or when coasting without power and holds it reliably in track.

    ESP complements the familiar functions of the anti-lock brake system (ABS), acceleration slip regulation (ASR) and engine braking regulation (EBR).

    The stability regulation function is superordinate to the ABS and ASR control systems. As well as actively intervening with the brakes, ESP also has an influence on engine/transmission management.

    The Electronic Stability Program (ESP) includes the following system interplay:

    ABS prevents the wheels from locking up during braking and thus maintains the steerability and directional control of the vehicle during deceleration.

    ASR prevents the drive wheels from spinning while driving. It also improves directional control with better traction across the entire speed range.

    EBR reduces brake slip at the drive wheels during deceleration and ensures directional control.

    ESP prevents the vehicle from breaking away when it is oversteered or understeered. In all situations, it ensures that the vehicle does not deviate from the course specified by the driver (within the bounds of physical limits). Brake forces are produced selectively at the individual wheels to correct this.
