CAUTION: Use the check board when measuring the ECM terminal voltage and resistance. Ref. to ENGINE (DIAGNOSTICS) (H4DO)>GENERAL PRESCRIPTION>PREPARATION TOOL>HOW TO USE CHECK BOARD .
NOTE: After the faulty parts are repaired or replaced, perform the final check in Basic Diagnostic Procedure. Ref. to ENGINE (DIAGNOSTICS) (H4DO)>BASIC DIAGNOSTIC PROCEDURE>PROCEDURE .
  1. CHECK HARNESS BETWEEN ECM AND M/B (STARTER RELAY) (OPEN)  .
    1. Turn the ignition switch to OFF.
    2. Disconnect the connector from ECM.
    3. Remove the starter relay.
    4. Measure the resistance of harness between ECM connector and M/B (starter relay) terminal No. 3.

      Connector and terminal 

      (B134) No. 27 - No. 3:

    Is the resistance less than 1 Ω?

    Yes  : Go to  2 .

    No  : Repair the open circuit of harness between ECM connector and M/B (starter relay).

  2. CHECK HARNESS BETWEEN ECM AND M/B (STARTER RELAY) (SHORT TO GROUND)  .
    1. Disconnect the connector from starter motor.
    2. Measure the resistance between the ECM connector and engine ground.

      Connector and terminal 

      (B134) No. 27 - Engine ground:

    Is the resistance 1 MΩ or more?

    Yes  : Repair the poor contact of ECM connector.

    No  : Repair the short circuit to ground in harness between ECM connector and M/B (starter relay).
