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

Brake light switch signal voltage becomes 4.8 – 8.0 V for
specified time.• Brake light circuit
• Brake light switch
• ABS control module
Step Action Yes No
1Was “ABS Check” performed?Go to Step 2. Go to “ABS Check”.
2Brake light operation check
1) Turn ignition switch to ON position and depress brake
pedal.
Does brake light turn ON?Go to Step 3. Repair brake light
switch, brake light and/
or brake light circuit and
recheck.
3Brake light switch signal circuit check
1) Disconnect ABS hydraulic unit / control module and
brake light switch connector with ignition switch turned
OFF.
2) Check for proper connection to “E08-7” terminal of ABS
hydraulic unit / control module and “GRN/WHT” wire
terminal of brake light switch.
3) If OK then measurer resistance between terminal of
“E08-7” and “GRN/WHT” wire terminal of brake light
switch connector.
Is it less than 2
Ω?Substitute a known-
good ABS hydraulic unit
/ control module and
recheck.“GRN/WHT” wire open
or high resistance.
