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.
Exiting Diagnostic Mode
To exit diagnostic mode with Super Monitor Display, either switch or push the Super Monitor Display key to display time.
For diagnostic mode without Super Monitor Display, remove voltmeter and adapter harness from "EFI" service connector. Remove jumper wire from "CHECK ENGINE" connector. Turn ignition off. Replace rubber caps over connectors. After cancellation, perform a road test to confirm that a "NORMAL" code is now read.
