Bulletin Summary
Service Bulletin for Lengthening the Backup Light Harness. Though the backup light harness is long enough to connect to the backup light switch, it may be short enough that the wire seals in the connector can be stressed. Moisture entering through the seals can cause corrosion, resulting in a bad connection and/or failure of the switch. As a result, backup lights and, if equipped, the backup alarm, may not function when the vehicle is shifted into reverse.
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.
