TF-210, "Transfer Control Unit Input/Output Signal
.
OK or NG
OK
>> GO TO 3.
NG
>> Check transfer control unit pin terminals for damage or loose connection with harness connector.
If any items are damaged, repair or replace damaged parts.
3.
CHECK DTC
Perform the self-diagnosis, after driving a vehicle for a while.
OK or NG
OK
>> Inspection End.
NG
>> Perform self-diagnosis with TCM again. Refer to
