CAUTION: Use the check board when measuring the ECM terminal voltage and resistance. Ref. 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. 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 & terminal (B134) No. 27 - No. 3:
  Is the resistance less than 1 ft?
  
  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 & 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).
