Troubleshooting
WARNING!
Keep hands, tools, and clothing away from radiator cooling fan to help prevent personal injury. This
fan is electric and can come on whether or not the engine is running. The fan can start automatically in
response to the ECT sensor with the ignition switch at the “ON” position.
NOTE
• Before performed trouble shooting, be sure to read the “Precautions of ECM Circuit Inspection”.
• When measuring circuit voltage, resistance and/or pulse signal at ECM connector, connect the
special tool to ECM and/or the ECM connectors referring to “Inspection of ECM and Its Circuits”.

Diagnostic Information and Procedures
Cranking System Symptom DiagnosisS6RW0D1904001
Possible symptoms due to starting system trouble would be as follows:
• Starting motor does not run (or runs slowly)
• Starting motor runs but fails to crank engine
• Abnormal noise is heard
Proper diagnosis must be made to determine exactly where the cause of each trouble lies in battery, wiring harness,
(including starting motor switch), starting motor or engine.
Do not remove motor just because starting motor does not run. Check the following items and narrow down scope of
possible causes.
1) Condition of trouble
2) Tightness of battery terminals (including ground cable connection on engine side) and starting motor terminals
3) Discharge of battery
4) Mounting of starting motor

Circuit Description
4WD position indicator operates according to the signal from 4WD control module. If the 4WD control system is in
good condition, 4WD position indicator light up for 2 seconds when ignition switch is turned to ON position, and then
turned to OFF position. If an abnormality is detected in the system, 4WD position indicator remains lighting.

4WD Position Indicator Remains ON Steady at Ignition Switch ONS6RW0D3204014
Wiring Diagram
Refer to “4WD Position Indicator Does Not Come ON at Ignition Switch ON but Engine Stops”.
Circuit Description
Transfer position indicator operates according to the signal from 4WD control module. If the 4WD control system is in
good condition, 4WD position indicator light up for 2 seconds when ignition switch is turned to ON position, and then
turned to OFF position. If an abnormality is detected in the system, 4WD position indicator remains lighting.
Troubleshooting3CAN communication circuit check
1) Check CAN communication circuit between combination
meter and 4WD control module referring to “DTC U0073:
Control Module Communication Bus Off”.
Is CAN communication circuit in good condition?Go to Step 4. Repair or replace.
4“METER” fuse check
1) Turn ignition switch to OFF position.
