Bulletin Summary
The vehicle alarm activates for no reason and it cannot be turned off. The alarm horn does not work. TC/fault symptom combinations are found in the comfort system control module, J393 (address word 46). The DTC can be static or sporadic. The wiring harness insulation for the alarm horn can be damaged during the vehicle production assembly. Because the cable is routed through the plenum chamber, water can enter into the cable via the damaged insulation. The water causes the alarm to activate for no reason or it causes the alarm horn to not work.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
