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

    Yes:  Go to  2.

    No:  Connect the ECM connector correctly.

  2. 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  .
    NOTE:
    • Poor contact of fuse (F/B No. 5) 
    • Poor contact of IG2 relay connector
