Complaint:
ESP®, BAS, PRE-SAFE®, HOLD function, Hill-Start Assist and ESP® trailer stabilization are unavailable due to a
malfunction. Also the adaptive brake lights, Adaptive Brake Assist and/or ATTENTION ASSIST may have failed or be
deactivated. The brake system continues to operate with normal effectiveness. The support functions listed may have
failed, but are available again after an ignition off/on cycle.
One or more of the faults relating to the accelerator pedal (B37) listed under 'Control unit / Fault code' are stored in
the engine control unit. Consequential faults may be stored in the ESP; see also under 'Control unit / Fault code'.
Cause:
The fault entry could have been caused by occasional transition resistance at contacts.
Remedy:
If all the test steps stored in Xentry Diagnostics have been performed and no component faults were found, the following work must be carried out:
- Check contacts of accelerator pedal plug connector (B37) for widening/damage! Make sure that testing is performed
using the correct contact spring (here MLK1.2) from the electrics case, otherwise the contact could be damaged! If damage/widening is found, the female contacts must be replaced.
- Disconnect engine control unit "plug connector - F and M" once and then reconnect.
Engines 651 and 270 only:
If the fault reoccurs, or if this is a reoccurrence of the same fault, the relevant female contacts of the engine control
unit connector "M" or "F" must be replaced. A PTSS case should be opened and MBUSA will dispatch a person to
perform the repair in the attached instructions!
Notes:
Contact spray must never be used on contacts on the engine wiring harness. The use of contact cleaners can cause
consequential damage!
Please do not replace any components!
