DIAGNOSIS:
Using a Scan Tool with the appropriate Diagnostic Procedures available in
TechCONNECT, verify all related systems are functioning as designed. If DTCs are
present, other than the ones listed above, record them on the repair order and repair as
necessary before proceeding further with this bulletin.
If a customer’s VIN is listed in VIP or your RRT VIN list, perform the repair. For all other
customers that describe the symptom/condition or if the technician finds any of the DTCs
listed above, perform the Repair Procedure.
REPAIR PROCEDURE:
NOTE: If DTC U1601 is present, the ECM P/N did not update, or the engine did not
start after the flash, then the flash may have been unsuccessful. Restart the
flash update.
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.
1. Reprogram the PCM with the latest available software. Detailed instructions for
flashing control modules using the wiTECH Diagnostic Application are available by
selecting the application’s “HELP” tab.
NOTE: After PCM reprogramming has completed successfully, the following must
be performed:
2. Power down the PCM (key off) after flash. Automatic Transmission equipped trucks
must have key off for 10 minutes. Manual Transmission trucks must have key off for
75 seconds.
3. Perform a Quicklearn procedure on vehicles equipped with a 68RFE Automatic
Transmission. Follow the detailed service procedures available in
DealerCONNECT/TechCONNECT, Service Info Section 08 - Electrical > 8E Electronic Control Modules > Module, Transmission Control > Standard Procedure >
Quicklearn.
4. Clear all DTCs that may have been set in any module due to reprogramming. The
wiTECH application will automatically present all DTCs after the flash and allow them
to be cleared.
5. Perform the PCM Configuration routine in wiTECH located in the PCM “Misc
Functions” menu tab.
6. Verify the Dosing Control Unit (DCU) is at the latest software calibration. Refer to all
applicable published service bulletins regarding DCU system improvements for
detailed repair procedures and labor times.

NOTE: The expected completion time for the flash download portion of this
procedure is approximately 14 minutes. Actual flash download times may be
affected by vehicle connection and network capabilities.
FAILURE CODE:
The dealer must choose which failure code to use. If the customer came in with an
issue and if the dealer finds a software update to correct that issue, use failure code
CC, for all other use failure code RF.
•
•

If the customer’s concern matches the SYMPTOM/CONDITION identified in the
Service Bulletin, failure code CC is to be used.
If an available flash is completed while addressing a different customer concern,
failure code RF is to be used.
