SYMPTOM DESCRIPTION
The Powertrain Control Module (PCM) software
calibration on about 287,665 of the above vehicles
may fail to properly monitor certain emission-related
diagnostic functions as required by California and
Federal regulations. In addition, the Power Inverter
Module (PIM) diagnostics allow for correct malfunction
detection but prevents natural fault healing after repair
actions. This issue prevents the clearing of permanent
fault codes (PFC)s in the PIM which is required by
regulation. This update will also address Diagnostic
Trouble Codes (DTC)s and PFCs (P0010, P0013,
P0020, P2135, P0121, P0221) that do not heal on the
2020 model year (RU) PHEV as well as a POC4A that
will not set unless communication fault U0624 is
present on the 2021 model year (RU) PHEV.
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 new vehicle inventory. Dealers should
complete this campaign service on these vehicles
before retail delivery. Dealers should also perform
this repair on vehicles in used vehicle inventory and
those vehicles in for service. Involved vehicles can be
determined by using the VIP inquiry process.

REPAIR TO BE PERFORMED
Update the calibration software in the PCM and the
PIM, comprised of the Hybrid Control Processor
(HCP) and Auxiliary Hybrid Control Processor
(AHCP).

COMPLETION REPORTING / REIMBURSEMENT
Claims for vehicles that have been serviced must be

Service Procedure

be at the latest release level before performing this procedure.
WARNING! The PCM, HCP and AHCP must be updated to the latest available software at the conclusion of
this repair procedure. Failure to update the HCP, AHCP modules following a PCM software update may
result in vehicle malfunctions.
NOTE: If this software update flash process is interrupted/aborted, the flash should be restarted.
NOTE: PHEV vehicles: it is normal for the high voltage charging lamp on the dash to flash like there is a
charging system failure while performing software updates.
1. 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.

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 on important improvements we would

We are recommending the following improvements be performed on certain [2017-2021 (RU)

WHY DOES MY VEHICLE NEED REPAIRS?
The Powertrain Control Module (PCM) software calibration on your vehicle may fail to
properly monitor certain emission-related diagnostic functions as required by California and
Federal regulations. In addition, the Power Inverter Module (PIM) diagnostics allow for
correct malfunction detection but prevents natural fault healing after repair actions. This issue
prevents the clearing of permanent fault codes in the PIM which is required by regulation.
HOW DO I RESOLVE THIS CUSTOMER SATISFACTION NOTIFICATION?
FCA US will repair your vehicle free of charge (software update and labor). To do this, your
dealer will update the PCM and PIM software. The estimated repair time is about 30 minutes.
In addition, your dealer will require your vehicle for proper check-in, preparation, and checkout 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

it as proof that the Customer Satisfaction Notification has been performed.
In order to ensure your full protection under the emissions warranty provisions, it is
