Thanks to our Partner, NAPA Autotech TrainingKey Points & Takeaways:The Problem:A 2023 Jeep Grand Cherokee (collision repair) came in with blind spot warning and parking aid malfunction lights on.No functionality in either system post-repair.Initial Diagnosis:Verified the concern (instrument cluster lit up with warnings).Used an aftermarket scan tool (Snap-on Ultra) and found:ADAS control module had multiple DTCs for open/short circuits on all radar sensors.Parking aid module had similar codes for ultrasonic sensors.Vehicle was hit in the passenger rear, leading to replacement of the bumper, harness, and rear hatch.Suspected Causes:Blown fuse (common culprit for multiple system failures).Crushed/damaged wiring harness (common after collisions).Module failure due to impact.Testing & Findings:Checked power and ground at the ADAS module—all good.Inspected wiring harness for damage (no visible issues).Critical Clue: Wire colors didn’t match the schematic.Initially dismissed as a common schematic error.Lat
