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.
Failure Reproduction Technique: Notes
If the PCM detects the failure of a signal from a sensor, a switch, a solenoid valve, or from another control unit, it stores Pending or Confirmed DTCs. Depending on the failure, a Confirmed DTC is stored in either the first or the second drive cycle. When a Confirmed DTC is stored, the PCM blinks the D indicator and/or turns on the MIL by a signal sent to the gauge control module via F-CAN.
