CAUTION: Use the check board when measuring the ECM terminal voltage and resistance. Refer to ENGINE (DIAGNOSTICS) (H4DO)>GENERAL DESCRIPTION>PREPARATION TOOL>HOW TO USE CHECK BOARD .

NOTE: After the faulty parts are repaired or replaced, perform the final check in Basic Diagnostic Procedure. Refer to ENGINE (Diagnostics) (H4DO)>Basic Diagnostic Procedure>PROCEDURE .

CHECK HARNESS BETWEEN ECM AND M/B (STARTER RELAY) A (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 & terminal
  
  (B62) 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).
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 & terminal
  
  (B62) 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).
