CAUTION: Use the check board when measuring the ECM terminal voltage and resistance. Ref. to ENGINE (DIAGNOSTICS) (H4DO 2.0 (EXCEPT FOR HEV))>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 2.0 (EXCEPT FOR HEV))>BASIC DIAGNOSTIC PROCEDURE>PROCEDURE .

CHECK ECM CONNECTOR .
Check the connecting condition of ECM connector.

Is the ECM connector correctly connected?

Yes: Go to 2.

No: Connect the ECM connector correctly.
CHECK INPUT VOLTAGE OF ECM .
1. Turn the ignition switch to ON.
2. Measure the voltage between ECM connector and engine ground while wiggling the harness between ECM connector and F/B connector.
  Connector and terminal
  
  (B134) No. 56 (+) - Engine ground (-):
  
  Is the voltage 8 V or more all the time?
  
  Yes: Even if DTC is detected, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.
  NOTE:
  In this case, the following items may be the cause of fault.
  - Poor contact of fuse (F/B No: 5)
  - Poor contact of IG2 relay connector
  - Poor contact of IG2 relay
  No: Repair the harness and connector.
  NOTE:
  In this case, repair the following item:
  - Poor contact of fuse (F/B No. 5)
  - Poor contact of IG2 relay connector
  - Poor contact of IG2 relay
