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.

Service Procedure
Reprogram PCM
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.

Dear [Name],
At FCA US LLC, we recognize that the success of our business depends on the satisfaction of
our customers. We are constantly monitoring the quality of our products and looking for
opportunities to improve our vehicles even after they are sold. Because your long-term
satisfaction is important to us, we are contacting you regarding an important improvement we
would like to make to your vehicle [1]. This will be done at no charge to you.
We are recommending the following improvements be performed on [2018 Model Year (WK)
Jeep Grand Cherokee] vehicles equipped with a 3.0L diesel engine.
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, 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 your Powertrain
Control Module (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 instrument cluster display before potentially setting P2463. Even with this
PCM update, as specified in the owner’s manual, please follow the messages on the instrument
cluster display related to the DPF self-cleaning mode to help prevent this DTC from setting.
HOW DO I RESOLVE THIS CUSTOMER SATISFACTION NOTIFICATION?
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.
TO SCHEDULE YOUR FREE REPAIR,
CALL YOUR CHRYSLER, DODGE, JEEP OR RAM DEALER TODAY
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.
We apologize for any inconvenience, but are sincerely concerned about your satisfaction.
Thank you for your attention to this important matter.
