Failure code
CC
Customer Concern
The dealer must use failure code CC with this Technical Service Bulletin.
• If the customer’s concern matches the SYMPTOM identified in the Technical Service Bulletin, failure
code CC is to be used.
• When utilizing this failure code, the 3C’s (customer’s concern, cause and correction) must be provided
for processing Technical Service Bulletin flash/reprogramming conditions.
DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in DealerCONNECT/
Service Library, verify all related systems are functioning as designed. If DTCs or symptom conditions, other
than the ones listed above are present, record the issues on the repair order and repair as necessary
before proceeding further with this bulletin.
If the customer describes a symptom/condition or if the technician finds a DTC listed above, perform the
repair procedure.

REPAIR PROCEDURE:
NOTE: The Dosing Control Unit (DCU) and Body Control Module (BCM) must be updated to the latest
available software at the conclusion of this repair procedure. Refer to all applicable published service
bulletins for detailed repair procedures and labor times regarding updating the DCU and BCM
software.
NOTE: Install a battery charger to ensure battery voltage does not drop below 13.2 volts. Do not
allow the charging voltage to climb above 13.5 volts during the flash process.
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.
NOTE: **Before the flash process you must refer to all applicable published service bulletins for the
DPM sensor related DTCs listed in this bulletin for DPM sensor repair procedures.
1. Refer to all applicable published service bulletins for the DPM sensor related DTCs listed in this bulletin
for DPM sensor repair procedures.**
2. Reprogram the PCM with the latest software. Detailed instructions for flashing control modules using the
wiTECH Diagnostic Application are available by selecting the application’s “HELP” tab.
3. Verify the Dosing Control Unit (DCU) is programmed with the latest available software. Refer to all
applicable published service bulletins for detailed repair procedures and labor times regarding
updating the DCU software.
4. Verify the Body Control Module (BCM) is programmed with the latest available software. Refer to all
applicable published service bulletins for detailed repair procedures and labor times regarding updating
the BCM software.
5. Clear any DTCs that may have been set in any modules due to reprogramming. The wiTECH application
will automatically present all DTCs after the flash and allow them to be cleared.
