Troubleshooting for CAN-DTCS6RW0D1104084
Perform this troubleshooting when CAN-DTC is detected.
NOTE
• When performing this troubleshooting, be sure to have full understanding of “Precaution on CAN
Troubleshooting” and observe it.
• It may be possible that CAN system has trouble because of fuse blown or low battery voltage.
Before troubleshooting, check to make sure that fuse, battery voltage and generator status are
normal.
• When performing “Communication Bus Check” using SUZUKI scan tool (SUZUKI-SDT) in each step
of this troubleshooting, use the following table to determine whether the control module is in good
condition or not.
Also, while performing “Communication Bus Check”, do not perform any work other than instructed
in this troubleshooting. Or, it may occur that display of control module/sensor on SUZUKI-SDT
screen and/or its background color may change.
• When disconnecting each control module connector in this troubleshooting, various DTCs will be
detected. Be sure to clear DTCs in the following control modules after completing this
troubleshooting.
–ECM
– BCM
–TCM
– Keyless start control module
– 4WD control module
– HVAC control module (Auto A/C model)
– P/S control module

Wiring Diagram
Refer to “Troubleshooting for Communication Error with Scan Tool Using CAN”.

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
