Models:
2014 GMC Sierra 1500
This PI was superseded to provide fix information. Please discard PIT5219.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern
Some technicians may find DTCs B2600 Sym 04 and B2605 Sym 04 set in the BCM with no other symptoms. These
two DTCs may falsely set if the DRLs are operated and the fog lamps are turned on. The lamps will work as
designed, and there will be no issues or customer complaints with the lamps.
Recommendation/Instructions
To correct these false DTCs from setting, updated the BCM with the latest calibrations in TIS2WEB.
Reference the latest version of Service Update Bulletin 13257 for repair procedure and warranty information.
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.
