Information: Beginning in December 2021, certain 2022 MY passenger car, crossover, SUV, and Truck models will be produced without the Front and Rear Park Assist Module or without the Rear Park Assist Module. For limited subset of the impacted models and configurations, the Removal of Front and Rear Park Assist (UD5) will also cause Reverse Braking (UVZ) to be non-functional. Some vehicles will be produced without the Park Assist switch, while some vehicles will be produced with Park Assist switch in place. For vehicles with the Park Assist switch in place, this switch may illuminate if depressed, but will not operate as the Park Assist feature is not available. Calibrations have been changed for the Park Assist function not being available. Version 1 Modified Released March 04, 2022. Vehicle models which are produced without Park Assist will be identified by including RPO: 00Y (Not Equipped with Rear Park Assist) or RPO: 00Z (Not Equipped with Front and Rear Park Assist), along with RPO: UD7 or UD5 with or without UVZ as equipped. Considerations for diagnosing electrical wiring concerns: System components related to Rear Park Assist (UD7), Front and Rear Park Assist (UD5) and Front and Rear Park Assist (UD5) with Reverse Automatic Braking (UVZ) will be unchanged in vehicles equipped with RPO: 00Y or 00Z, along with RPO: UD7, UD5 and UVZ as equipped, with exception of the Park Assist Module, and for some vehicles the Park Assist Switch. When diagnosing and repairing concerns with electrical function which may be related to the Park Assist related hardware; utilize appropriate diagnostics within SI and replace any needed components as directed by the Electronic Parts Catalog. Important: Vehicles designated with RPO: 00Y or RPO: 00Z are planned to have a future update to enable the Park Assist feature. Do Not attempt to enable this content apart from official direction for retrofit. 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. WE SUPPORT VOLUNTARY TECHNICIAN CERTIFICATION
