YES

>> Erase self-diagnosis results for “METER/M&A”. Then perform self-diagnosis for “METER/M&A”

with CONSULT.

NO

>> Recheck terminals for damage or loose connection. Refer to 

LAN-7, "Precautions for Harness

Repair"

.

4.

CHECK APPLICABLE CONTROL UNIT

Check damage or loose connection of each CAN communication line harness connector terminals.
Is the inspection result normal?

YES

>> Erase self-diagnosis results. Then perform self-diagnosis for applicable control unit with CON-

SULT.
