Service bulletin A571390 2034071-

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

The customer reports that the alarm goes off for no reason. The passenger door control module, J387 (address word 52), has software version 0273 ? only this version is affected. Measuring value blocks 21-24 in the Comfort system central control module, J393 (address word 46), indicate the last alarm source. A value of 1, 2 or 3 is stored as the last alarm source. Incorrect coding/parameterization of the passenger door control module.
