.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000012197742

1.

CHECK DRIVETRAIN CAN COMMUNICATION HARNESS AND CONNECTORS

1. Turn ignition switch OFF.

2. Check installation condition of ECM and FPCM.

3. Disconnect ECM harness connector and FPCM harness connector.

4. Check the continuity between ECM harness connector and FPCM harness connector.

5. Also check harness for short.
Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace error-detected parts.

2.

PERFORM DTC CONFIRMATION PROCEDURE AGAIN

With CONSULT

1. Reconnect all harness connector disconnected.

2. Turn ignition switch ON.

3. Erase “Self Diagnostic Result” of “FPCM”.

4. Perform DTC confirmation procedure again. Refer to 

EC-191, "DTC Description"

.

Is DTC “U0100” detected again?

DTC 

No.
