The purpose of this bulletin is to notify dealership personal that some 2021–2022 Tahoes
were ordered without RPO 6J7 which provides the flashing headlamps and taillamps.

This may be due to some confusion on which other calibrations need to be added to
provide RPO 5J9 Red/White flashing taillamps or RPO 5L0 Red/Red flashing taillamps.
Correction
Technicians need to inform the Techline consultant that they need to add RPO 6J7 to the

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.
