DIAGNOSIS:

Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all vehicle 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 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 listed above or if the technician finds the DTC, perform the Repair Procedure.

 

REPAIR PROCEDURE:

NOTE: Install a battery charger Flash: 3.0L Powertrain Diagnostic And System Enhancements - 2015 Jeep Grand Cherokee | small light 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. Using wiTECH, check the PCM calibration and see if it is up to date. Does the PCM software need to be updated?
    • Yes >>> Proceed to Step #2.
    • No >>> The RRT has been completed. Use inspection LOP 18-19-04-DK to close the active RRT.
  2. Reprogram the PCM with the latest available software. Detailed instructions for flashing control modules using the wiTECH Diagnostic Application are available by selecting the “HELP” tab on the upper portion of the wiTECH window, then “HELP CONTENTS.” This will open the Welcome to wiTECH Help screen where help topics can be selected.
  3. 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.
  4. Under the PCM “System Tests” perform the “SCR DEF Tank Fluid Level Reset” procedure.
  5. Turn the ignition off for 35 seconds to complete the flash.
