Disabling Rear Park Assist
By Blog Post on January 1, 2011 6:07 PM | No Comments
On 2007-2011 Silverado and Sierra models, owners or aftermarket upfitters that remove the rear bumper, install a different rear bumper, add a different box/flat bed/cube box/hitch or make other modifications to the rear of the truck, may need to disable the Rear Park Assist option (RPO UD7) from the vehicle.
Follow the instructions below for the model year of the vehicle involved:
1. For all model years, disable the Rear Park Assist module by removing the OBS DET fuse 20 (10 amp) from the left instrument panel fuse block
2a. For 2007-2009 models, contact Techline Customer Support at 1-800-828-6860 to obtain an Instrument Panel Cluster (IPC) calibration to disable the Rear Park Assist option.
2b. For 2010-2011 models, remove power to the IPC for several minutes by disconnecting the battery and then reconnect. When power is restored, the IPC will not see the Park Assist Module (disabled in Step 1) on the low speed data buss. It will reconfigure the IPC without Rear Park Assist. After this process is complete, the Park Assist Warning Messages will not be displayed.
