| CHECK HARNESS BETWEEN ECM, STARTER RELAY CONNECTOR AND STARTER MOTOR CONNECTOR. |
|
1) Disconnect the connectors from ECM. 2) Turn the ignition to ON. 3) Measure the voltage between ECM and chassis ground. Connector & terminal Euro 4 model (B136) No. 35 (+) — Chassis ground (−): Euro 5 model (B135) No. 20 (+) — Chassis ground (−): |
| QUESTION | |
|
Is the voltage 10 V or more? | |
| Yes | No |

Repair the short circuit to power supply. NOTE: In this case, repair the following harnesses: • Short circuit to power supply in harness between ECM and starter relay connector • Short circuit to power supply in harness between ECM and starter motor connector • Short circuit to power supply in harness between starter relay connector and starter motor connector |
Repair the poor contact of ECM connector. |
