DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in TechCONNECT, 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 the symptom/condition listed above or if the technician finds the DTC, 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.
- 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:
- 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.
- 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.
- 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.
- Perform the PCM Configuration routine in wiTECH located in the PCM “Misc Functions” menu tab.
- 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.
POLICY:
Reimbursable within the provisions of the warranty.
