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.
Ignition Switch Circuit
Turn ignition off and disconnect ATS ECU connector. Turn ignition to ACC or ON position. Ensure battery voltage exists between ground and ECU connector terminal B7 (with power door locks, Gray wire) or No. 6 (without power door locks, Gray wire). If battery voltage is not present, repair open in harness or connectors between fuse and terminal(s) as necessary. If battery voltage is present, replace ATS ECU and retest.
