Diagnosis Procedure
INFOID:0000000005258387
Regarding Wiring Diagram information, refer to
DLN-240, "Wiring Diagram - PART TIME 4WD SYSTEM -"
1.
CHECK 4WD SHIFT SWITCH SIGNAL
With CONSULT-III
1. Turn ignition switch “ON”.
2. Select “DATA MONITOR” mode for “ALL MODE AWD/4WD” with CONSULT-III.
3. Read out ON/OFF switching action of the “2WD SWITCH”, “4H SWITCH”, “4L SWITCH” with operating
4WD shift switch.
Without CONSULT-III
1. Turn ignition switch “ON”.
2. Check voltage between transfer control unit harness connector
terminals and ground.
Are the inspection results normal?
YES
>> GO TO 5.
