SERVICE PARK ASSIST displays in your dash when the object alarm module detects a malfunction in the detection system or when there is a loss of communication with the object alarm module.. I have an 07 Denali Yukon. Backed into my truck and damaged 2 sensors. Got the "service park assist" DIC and the switch on dash to enable/disable stays.
Hello! I keep getting service park assist pop up. When I put my car in reverse my backup camera is showing red for all four of my back sensors. Any suggestions on what I should start with replacing? 2015 Tahoe LT. Hi Derek.The "Service Park Assist" message on your 2017 GMC Yukon indicates a potential issue with the park assist system.
