Does the C-CM pass the network test? 

• Yes: GO to 3  .
• No: REFER to DIAGNOSTIC ROUTINE U : The Cruise-Control Module (C-CM) Does Not Respond To The Scan Tool.

1. Check for recorded BCM DTCs  from the self-test.

Is DTC U3003:16 or DTC U3003:17 recorded? 

• Yes: For DTC U3003:16, REFER to Diagnostic Routine H: DTC U3003:16 .

  For DTC U3003:17, REFER to Diagnostic Routine I: DTC U3003:17 .

• No: GO to 4  .

1. Using a scan tool, retrieve the continuous memory DTCs  from the C-CM  .

Is DTC U3003:16 or DTC U3003:17 recorded? 

• Yes:

  For DTC U3003:16, REFER to DIAGNOSTIC ROUTINE Q : U3003:16.

  For DTC U3003:17, REFER to DIAGNOSTIC ROUTINE R : U3003:17.

• No: GO to 5  .

1. NOTE: If new modules were installed prior to the DTC being set, the module configuration may be incorrectly set during Programmable PMI or the PMI may not have been carried out.

   Using a scan tool, perform BCM Self-Test.

2. Clear the DTCs  . Repeat the BCM self-test.

Is DTC U0104:00 still present? 

• Yes: GO to 6  .
• No: The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.

1. Clear the DTCs  .

4. Wait 10 seconds.
5. Using a scan tool, retrieve the continuous memory DTCs  from all modules.

Is DTC U0104:00 set in any other module 

• Yes: INSTALL a new C-CM  . REFER to CRUISE CONTROL MODULE (C-CM) .
• No: INSTALL a new BCM. REFER to Body Control Module (BCM) - with Intelligent Access (IA)  or REFER to Body Control Module (BCM) - without Intelligent Access (IA) .
