1.
CHECK WAIT DETECTION SWITCH SIGNAL
With CONSULT-II
1.
Start engine.
2.
Select “DATA MONITOR” mode for “ALL MODE AWD/4WD” with CONSULT-II.
3.
Read out the value of “WAIT DETCT SW”.
Without CONSULT-II
1.
Start engine.
2.
Check voltage between transfer control unit harness connector
terminal and ground.
OK or NG
OK >> GO

5.
NG
>> GO TO 2.
2.
CHECK HARNESS BETWEEN TRANSFER CONTROL UNIT AND WAIT DETECTION SWITCH
1.
Turn ignition switch “OFF”. (Stay for at least 5 seconds.)
2.
Disconnect transfer control unit harness connector and the wait detection switch harness connector.
3.
Check continuity between transfer control unit harness connec-
tor M152 terminal 17 and wait detection switch harness connec-
tor F59 terminal 10.
Also check harness for short to ground and short to power.
