1. VERIFY DTC IS ACTIVE NOTE: Make sure the IOD fuse is installed and battery voltage is between 10 and 16 volts before proceeding. With the scan tool, read active DTC's. Is this DTC active? Yes Go To 2 . No Refer to «STORED LOST COMMUNICATION DTC's»(ref-476525-S35361024732012060400000) and perform the diagnostic procedure.
2. CHECK FOR ANY OF THE FOLLOWING ACTIVE DTC's With the scan tool, read all active DTC's from all modules. NOTE: Check for TIPM configuration, CAN Interior Bus hardware electrical, VIN Missing/Mismatch, battery or ignition related DTC's. Does the scan tool display any active DTC's to the conditions listed above? Yes Go to «DIAGNOSTIC CODE INDEX»(ref-476553-S13841779632012060400000) and perform the appropriate diagnostic procedure. No Go To 3 .
3. VERIFY THE CCN IS ACTIVE ON THE BUS Turn the ignition on. With the scan tool, select Network Diagnostics. Verify the CCN is active on the bus. Is the CCN active on the bus? Yes Go To 4 . No Refer to «NO RESPONSE FROM CCN (CLUSTER)»(ref-476525-S29473327892012060400000) and perform the diagnostic procedure.
4. CHECK FOR ADDITIONAL COMMUNICATION RELATED DTC's With the scan tool, select Network Diagnostics. Is there more than one module with active DTC's "Logged Against" the CCN? Yes Replace/update the Cluster/CCN in accordance with the Service Information. Refer to «REMOVAL»(ref-476514-S25394978592012060400000) . Perform the BODY VERIFICATION TEST. Refer to «BODY VERIFICATION TEST»(ref-476553-S41648749512012060400000) . No Go To 5 .
5. CLEAR DTC IN MODULE SETTING FAULT With the scan tool, select the module setting the DTC against the Cluster/CCN. Clear active DTC's. Is this DTC still active? Yes Replace/update the module that set this DTC in accordance with the Service Information. Perform the appropriate verification test for the module being replaced.
