SUBJECT: Hazard Warning Lights and Interior Lights Come on, Central Locking System Unlocks

MODELS: 8 Series (E31) - Vehicles Produced 9/90 through 10/90


Situation: Central locking system crash sensors (P/N 61 31 1 388 224) on the vehicles listed below may have been incorrectly mounted. When driving over hard, bumpy surfaces, or when releasing the hood release handle rapidly, the following may occur:

- Hazard warning flashers and interior lights are switched on;

- Central locking system unlocks, rendering all functions of the central locking system inoperative.

Note: The crash sensor input is only recognized by the General Module when the ignition switch is in the "RUN" position (position 2, KL15). SRS operation is not affected by this situation, As an immediate remedy, if these symptoms occur, the hazard warning light switch must be pressed twice, and the ignition switch turned OFF to reset the systems.
