Fault-Tracing Information

• This fault-tracing only applies to vehicles with the symptom Starter motor not running.
• If the starter motor turns but the engine does not start, finish this fault-tracing.

Do you want to continue with this procedure? 

• YES 

  Refer to CHECKING THE DIAGNOSTIC TROUBLE CODES (DTCS) 

• NO 

  FAULT NOT FOUND:  Troubleshooting has been completed.

The malfunction was caused by the steering column being loaded.

The fault has now been remedied.

• Continue 

  Refer to VERIFICATION 

The fault must be diagnosed and remedied.

If no malfunction has been found in any of the diagnostic tests, report the result of the troubleshooting to the sales company/importer according to normal report procedure.

• Continue 

  FAULT TRACING FAILED:  The fault should have been detected and remedied. As this is not the case fault-tracing has failed. Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

• Troubleshoot diagnostic trouble code CEM-DD 10.

• Troubleshoot diagnostic trouble code CEM-6C41.

• Ignition off.
• Check relevant fuses for Central electronic module (CEM) and Start control module (SCU).
• Check cables and connections to Central electronic module (CEM).
• Check cables and connections to Start control module (SCU).

  Refer to CHECKING THE IGNITION SWITCH 

Is the vehicle equipped with a Gas discharge lamp module (GDL)? 

• YES 

  Refer to CHECK LIN DIAGNOSTIC TROUBLE CODES (DTCS) 

• NO 

  Refer to REPLACING THE CENTRAL ELECTRONIC MODULE (CEM) 

• Troubleshoot current LIN diagnostic trouble codes.

If the starter motor runs, the problem is one of the following:

• Damaged starter motor relay.
• Voltage feed from the ignition to the starter motor relay when cranking.(For certain engine versions via Engine control module (ECM).)
• Engine control module (ECM) does not ground the starter motor relay.

Start troubleshooting by replacing starter motor relay.

Check cable and voltage feed between ignition and starter motor relay.

The reason for the Engine control module (ECM) not being able to activate (grounding) the starter motor relay may be:

• The signal from the clutch pedal sensor via CAN indicates that the clutch pedal is not pressed down enough.
• The signal from the brake pedal position sensor indicates that the brake pedal is not pressed down enough (only applies to the starting conditions that require brake pedal to be pressed down).
• The gear selector's signal (automatic transmissions) for P and N is incorrect.
