6.CHECK HARNESS BETWEEN ECM, F/B STARTER RELAY CONNECTOR AND STARTER MOTOR.

1) Disconnect the connector from ECM.

2) Turn the ignition to ON.

3) Measure the voltage between ECM connector and chassis ground.

Connector & terminal

(B134) No. 58 (+) — Chassis ground (−):

Is the voltage 10 V or more-

Repair the short circuit to power supply.

NOTE:

In this case, repair the following harnesses:

Short circuit to power supply in harness between ECM connector and starter relay connector

Short circuit to power supply in harness between ECM connector and starter motor

Short circuit to power supply in harness between starter relay connector and starter motor

Repair the poor contact of ECM connector.

3. OUTLINE OF DIAGNOSIS

Model without push button start

Detect abnormal continuity in the starter SW1.

Judge as ON NG when the starter SW 1 signal remains ON.

Model with push button start

Detect abnormal continuity in the starter SW 2.

Judge as ON NG when the starter SW 2 signal remains ON.
