Supersession Statement
This PI was superseded to add the 2019 models. Please discard PIT5412C.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition / Concern
Some owners with snow plow equipment, may notice that either the truck or the snowplow’s
headlights are flickering or Inoperative. This may affect either the LH or the RH lamp
assembly. This may also occur when switching back and forth between the truck and the
snow plow headlights. When checking for DTC’s, the BCM may or may not set a B2575 and/or
B2699.
Some snow plow manufacturers offer a headlight changeover module for switching between
the truck’s headlights and the snowplow’s headlights. Depending on the type of headlights
the truck is equipped with and the way they are controlled the headlight changeover module
may not operate correctly with the truck’s headlight system. This can cause either or both
the truck or snow plow headlights to flicker during changeover.
Recommendations / Instructions
This is not an issue with the truck’s headlight system. Contact the snowplow
manufacturer/upfitter for additional information on their headlight changeover system.
Also, please reference the latest version of GM Upfitter Integration Bulletin 116 for
additional information on these circuits. It can be found at https://www.gmupfitter.com/,
under the “Technical Bulletin” Tab and then “Show all bulletins.”
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.
