GCUS-9-883

14609 - Special Coverage. On certain 2004-2009 model year Chevrolet Colorado and GMC Canyon extended cab vehicles, the wires in the rear-door-wire harness may fatigue and break. If one or more of the wires break, the vehicle?s airbag readiness light/SIR light will illuminate. A broken wire may also trigger diagnostic trouble codes(s) (DTC) B0057, B0058, B0059, B0064, B0065, and B0066, and could also disable the front driver/passenger seat-belt pretensioner. This condition does not affect the operation of the vehicle?s airbags. Dealers are to replace the rear door wire harness.
