Complaint:
ESP®, BAS, PRE-SAFE®, HOLD function, Hill-Start Assist and ESP® trailer stabilization may be unavailable, and the
adaptive brake lights, Adaptive Brake Assist and/or ATTENTION ASSIST may be deactivated. The brake system continues to operate with normal effectiveness. The support functions listed will be available again after an ignition off/on
cycle.
One or more of the faults listed under 'Control unit/fault code' for the accelerator pedal (B37) is logged in the PTCU
control unit (N127). Consequential faults may have been logged in the ESP control unit.
Cause:
The fault entry could have been caused by occasional high resistance at contacts.
Remedy:
The remedy refers only to the model series listed and is not compatible with other published TIPS documents for other
model series.
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:
1.
2.
3.
Replace the connector/ feed line to the accelerator pedal sensor (B37) using the wiring harness repair kit (see
parts table).
Please ensure that the twisted lines are untwisted as little as possible.
Please do not replace any other components (e.g. accelerator pedal sensor).
Reoccurrence of the complaint:
•
•
•
If the fault occurs again, or if this is a reoccurrence of the same complaint, please make sure that the line
connectors between the repair wiring harness and the interior wiring harness are fitted correctly and that the solder has dispersed evenly.
In case of doubt, please repeat the repair. Historically, we have seen repetition of the repair to be effective.
If the complaint reoccurs after the second repair attempt, please create a PTSS case with informative photos of
all line connectors.
