SERVICE CAMPAIGN BULLETIN

Reference Number(s): RC-W41-20, Date of Issue:  July 29, 2020
CHRYSLER: 2014-2016 (WK) Jeep® Grand Cherokee

REMEDY AVAILABLE

2014-2016 (WK) Jeep® Grand Cherokee 

NOTE: This campaign applies only to the above vehicles equipped with a 3.0L diesel engine that have received Emissions Recall V08/V11/V16/VA7.
NOTE: Some vehicles above may have been identified as not involved in this campaign and therefore have been excluded from this campaign.
IMPORTANT: Some of the involved vehicles may be in dealer used vehicle inventory. Dealers should complete this campaign service on these vehicles before retail delivery.  Dealers should also perform this campaign on vehicles in for service that have received V08/V11/V16/VA7,  but they should do so only with the customer's consent. Involved vehicles can be determined by using the VIP inquiry process.

SUBJECT

The above vehicles are equipped with a diesel particulate filter (DPF) that is designed to capture particulate matter (PM) that is formed in the engine. As explained in the owner's manual, the DPF has a self-cleaning mode to remove accumulated PM. If the DPF is not able to complete this self-cleaning, Diagnostic Trouble Code (DTC) P2463 (Diesel Particulate Filter Restriction - Soot Accumulation) may set. This would result in a Malfunction Indicator Lamp (MIL) and engine derate until the vehicle is serviced at a dealership. This update to the Powertrain Control Module (PCM) should help to reduce the total amount of time that the above vehicles need to spend in this self-cleaning mode and may increase the amount of time for the customer to respond to the message on the instrument cluster before potentially setting P2463.

REPAIR

Inspect the current PCM software level and perform an update if a newer version of software is available.

PARTS INFORMATION

No parts are required to perform this service procedure.

PARTS RETURN

No parts return required for this campaign.

SPECIAL TOOLS

The following special tools are required to perform this repair: 

SERVICE PROCEDURE

Reprogram PCM

CAUTION: For 2014 model year vehicles, do not interrupt the PCM software update process in any way once it has begun. It may cause permanent damage to the PCM which will require replacement. For 2014 model year vehicles it is highly recommended to have a new generic PCM unit available at the workshop before starting the Repair Procedure.
NOTE: The wiTECH scan tool must be used to perform this recall. The wiTECH software is required to be at the latest release level before performing this procedure.
  1. Open the hood. Install a battery charger and verify that the charging rate provides 13.0 to 13.5 volts. Do not allow the charger to time out during the flash process. Set the battery charger timer (if so equipped) to continuous charge.
    NOTE: Use an accurate stand-alone voltmeter. The battery charger volt meter may not be sufficiently accurate. Voltages outside of the specified range will cause an unsuccessful flash. If voltage reading is too high, apply an electrical load by activating the park or headlamps and/or HVAC blower motor to lower the voltage.
  2. Connect the wiTECH micro pod II to the vehicle data link connector.
  3. Place the ignition in the "RUN  " position.
  4. Open the wiTECH 2.0 website.
  5. Enter your "User id"  and "Password"  and your "Dealer Code",  then select "Sign In"  at the bottom of the screen. Click "Accept". 
  6. From the "Vehicle Selection"  screen, select the vehicle to be updated.
  7. From the "Action Items"  screen, select the "Topology"  tab.
  8. From the "Topology"  tab, select the "PCM" module icon.
  9. From the "Flash"  tab, compare the "Current Electronic Control Unit (ECU) Part Number"  with the "New ECU Part Number"  listed.
    • If the "Current ECU part Number" is the same as the "New Part Number",  proceed to Step   14 . 
    • If  the "Current ECU part Number" is NOT the same as the "New Part Number",  continue with Step 10. 
  10. From the PCM tab, select the PCM flash part number. Read the flash special instructions page. Select "OK" to continue.
  11. From the flash ECU agreement page, agree to terms by checking the box.
  12. Select "Flash ECU"  and then follow the wiTECH screen instructions to complete the flash.
  13. Confirm the software is at the latest available calibration level.
  14. Click "View DTCs", select "Clear All DTCs",  click "Continue"  and then click "Close".  An ignition switch off/on cycle may be necessary to clear the DTCs.
  15. Turn the ignition to the "OFF"  position.
  16. Disconnect the wiTECH micro pod II from the vehicle.
  17. Remove the battery charger from the vehicle.
  18. Return the vehicle to the customer.

NOTIFICATION OF UPDATE TO APPROVED EMISSIONS MODIFICATION FOR JEEP GRAND CHEROKEE VEHICLES

Dear [Name],

This notice applies to your vehicle, 

[Model Year and Model] 

VIN XXXXXXXXXXXXXXXXX 

W41 

LOGO 

VEHICLE PICTURE 

At FCA US LLC, we recognize that the success of our business depends on the satisfaction of our customers. Our records indicate that you own or lease a model year 2014-2016 Jeep Grand Cherokee vehicle equipped with a 3.0L diesel engine (EcoDiesel)[1] and that you recently had an authorized Chrysler/Dodge/Jeep®/Ram dealership perform Emissions Recall V08/V11 to install the Approved Emissions Modification ("AEM"). As you may recall, FCA US offered you the AEM pursuant to an agreement with the U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) that required changes to the emission control system software intended to ensure that the vehicles' emissions are in compliance with the emissions standards to which they were originally certified. FCA US has observed an increase in occurrences of Diagnostic Trouble Code (DTC) P2463 (Diesel Particulate Filter Restriction - Soot Accumulation) setting in Jeep Grand Cherokees vehicles updated with the AEM as compared to vehicles without the AEM. To help address this, we have prepared an update to the powertrain control module (PCM) that will be provided at no additional cost to you.

WHY DOES MY VEHICLE NEED REPAIRS? 

Your vehicle is equipped with a diesel particulate filter (DPF) that is designed to capture particulate matter (PM) that is formed in the engine. As explained in the owner's manual, the DPF has a self-cleaning mode to remove accumulated PM. If the DPF is not able to complete this self-cleaning, DTC P2463 may set. This would result in a Malfunction Indicator Lamp (MIL) and engine derate until the vehicle is serviced at a dealership. This update to your PCM should help to reduce the total amount of time that your vehicle needs to spend in this self-cleaning mode and may increase the amount of time to respond to the message on the [Electronic Vehicle Information Center]/[Driver Information Display] before potentially setting DTC P2463. Even with this PCM update, as specified in the owner's manual, please follow the messages on the [Electronic Vehicle Information Center]/[Driver Information Display] related to the DPF self-cleaning mode to help prevent this DTC from setting.

HOW DO I RECEIVE THE UPDATED AEM? 

FCA US will repair your vehicle free of charge (parts and labor). To do this, your dealer will inspect the current PCM software level and perform an update if a newer version of software is available. The estimated repair time is 30 minutes. In addition, your dealer will require your vehicle for proper check-in, preparation, and check-out during your visit, which may require more time. Your time is important to us, so we recommend that you schedule a service appointment to minimize your inconvenience. Please bring this letter with you to your dealership.

WHAT IF I ALREADY PAID TO HAVE THIS REPAIR COMPLETED? 

If you have already experienced this specific condition and have paid to have it repaired, you may visit www.fcarecallreimbursement.com  to submit your reimbursement request online.[2] Once we receive and verify the required documents, reimbursement will be sent to you within 60 days. If you have had previous repairs performed and/or already received reimbursement, you may still need to have the repair performed.

TO SCHEDULE YOUR FREE REPAIR, CALL YOUR CHRYSLER, DODGE, JEEP OR RAM DEALER TODAY 

We apologize for any inconvenience, but are sincerely concerned about your satisfaction. Thank you for your attention to this important matter.
