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.

  1. Reprogram the ECM/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.
  2. Is this vehicle equipped with the 68RFE automatic transmission?
    • YES >>> Proceed to Step #3.
    • NO >>> Turn ignition key OFF for 75 seconds then proceed to Step #5.
  3. Turn ignition key OFF for 10 minutes.
  4. Perform the transmission “Quicklearn” procedure. Follow the detailed service procedures available in DealerCONNECT/TechCONNECT, Service Info Section 08 Electrical > 8E – Electronic Control Modules > MODULE, Transmission Control > Standard Procedure > Quicklearn.
  5. 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.
  6. Perform the PCM Configuration routine in wiTECH located in the PCM “Misc Functions” menu tab.
  7. Verify the Dosing Control Unit (DCU) software is up to date in accordance with the service procedures and labor times outlined in all applicable published service bulletins.

 

POLICY:

Reimbursable within the provisions of the warranty.

 

TIME ALLOWANCE:

Labor Operation No: Description Skill Category Amount
**18-19-04-GH Module, Engine Control/Powertrain Control (ECM/PCM) (Manual Trans/Aisin) – Reprogram (1 – Semi-Skilled) 10 – DIESEL 0.4 Hrs.
18-19-04-GJ Module, Engine Control/Powertrain Control (ECM/PCM) 68RFE Trans Only Reprogram (1 – Semi-Skilled) 10 – DIESEL 0.6 Hrs.**

 

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.
