The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern
After installing the GM Accessory Heated Seat Kit, one or more of the following issues may be present:
–
The heated seat back and/or bottom turns off after approximately 30 seconds
–
After turning on the heated seat switch, the indicators remain on, but the seat is not heating
–
DTCs B1935 Sym 0E, B2180 Sym 0E, B2425 Sym 0D, and/or B2430 Sym 0D
This concern could be caused by the seat back and bottom element connectors reversed. The accessory heated seat wiring harness contains two identical
connectors for the seat heater elements. The longer lead, which is covered with convoluted tubing, goes to the seat back heater element connector. The
shorter lead, which is only covered with tape, goes to the seat bottom heater element.
Recommendation/Instructions
Inspect the accessory heated seat wiring harness and make sure the heater element connectors are installed correctly. If not, install properly and retest.
Warranty Information
There is not a labor time or labor operation associated with this PI because the labor time is considered part of the original installation.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the
remaining steps do not need to be performed.
GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may
occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools,
safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that
your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
