Inspection steps
- Check ECM connector
- Check ECM input voltage.
- Turn the ignition switch to ON.
- Measure the voltage between the ECM connector, chassis connector, and chassis ground, while wiggling the harness between the ECM connector and the ignition switch connector (for models without push start) or the harness between the ECM connector and IG relay 1 (for models with push start).
Inspection terminals Inspection conditions Standard value A33-27 (IGSW) - chassis ground IG ON 8 V or more NG: Repair harness, connector, and switch.
OK: System is normal. The circuit returns to normal at this point even if a DTC is detected.
