Subject:
Driver or Passenger Door Module DTC B2555
Models:
2007-2013 Chevrolet Avalanche, Silverado, Suburban, Tahoe
2007-2013 GMC Sierra, Yukon Models
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern
DTC B2555 may be found in a Driver and/or Passenger Door Module (DDM and/or PDM). This DTC is associated
with front driver and passenger door panel courtesy lights that are only available on certain models. The door
module calibrations are the same if equipped with or without the door panel courtesy lights - meaning DTC B2555
may set on a vehicle NOT equipped with the front door panel courtesy lights.
Recommendation/Instructions
DTC B2555 should be ignored if set in a DDM and/or PDM on a vehicle NOT equipped with front door panel courtesy
lights.
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.
