DIAGNOSTIC PROCEDURE
1.CHECK ACTUATOR POSITION SWITCH SIGNAL
With CONSULT-II
1. Start engine.
2. Depress brake pedal and stop vehicle.
3. For A/T models, move A/T selector lever to “N” position. For M/T models, move M/T shift lever to neutral
position.
4. Select “DATA MONITOR” mode for “ALL MODE AWD/4WD” with CONSULT-II.
5. Read out the value of “SHIFT POS SW1”, “SHIFT POS SW2”,
“SHIFT POS SW3”, “SHIFT POS SW4”.
Without CONSULT-II
1. Start engine.
2. Depress brake pedal and stop vehicle.
3. For A/T models, move A/T selector lever to “N” position. For M/T models, move M/T shift lever to neutral
position.
4. Check voltage between transfer control unit harness connector
terminal and ground.
OK or NG
OK >> GO TO 4.
NG >> GO TO 2.
