Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Verification Test
Reconnect all previously disconnected components and wiring. If battery or BCM has been disconnected, or any work has been performed on ATC system, use DRB to calibrate ATC doors. Turn ignition off, then on. Use DRB to erase fault codes. Operate system that was malfunctioning to verify correct operation. If system still malfunctions, go to IDENTIFYING VEHICLE EQUIPMENT & SYSTEM PROBLEMS. Testing/repairs are complete if ATC system operates properly.
