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.
How To Treat Past Trouble
Since the trouble may still be present even the status is "Stored", set the vehicle to the diagnostic trouble code detection condition and check that the status changes to "Active". If the status does not change from "Stored", carry out the following procedure.
- Establish from the customer whether a fuse or connector has been replaced or disconnected.
- If yes, erase the diagnostic trouble code, and then check that no diagnostic code is reset. If no diagnostic trouble code is reset, the diagnosis is complete.
- If no, follow the applicable Diagnostic Trouble Code Chart. Then check the wiring harness and connector, and refer to "HOW TO COPE WITH INTERMITTENT MALFUNCTION ."
