Service bulletin LI54.18-P-067550

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Complaint ESP®, BAS, PRE-SAFE®, HOLD function, Hill-Start Assist and ESP® trailer stabilization are unavailable. Also the adaptive brake lights, Adaptive Brake Assist and/or ATTENTION ASSIST may be unavailable. The brake system continues to operate with normal effectiveness. The support functions listed may be unavailable, but are 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 may have been caused by 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 Diagnosis have been performed and no component faults were found, the following work must be carried out: - 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).
