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.
Monitor Description: Notes
The battery supplies power to the ECM even when the ignition switch is OFF. This power allows the ECM to record data such as DTC history, freeze frame data, and F/B learning values. When the battery voltage falls below the minimum level, memory becomes cleared, and the ECM judges it as a power supply circuit malfunction. When the engine is started subsequently, the ECM turns on the MIL and records the DTC.
| DTC No. | DTC detection conditions | Suspected parts |
