2025 Jeep Compass PCM Software Update TSB 18-057-25

Important Warnings and Market Information

This Technical Service Bulletin (TSB) 18-057-25 specifically applies to 2025 Jeep Compass vehicles built on or after January 02, 2025, and on or before May 16, 2025. It is important to note that this bulletin is not applicable to vehicles built for the US Market; instead, it primarily applies to the South America market, as well as NA, SA, EE, and CH markets. Owners in the US market should not expect to receive notifications or have this TSB apply to their vehicles.

When the repair procedure is performed, technicians must install a battery charger to maintain battery voltage between 13.2 and 13.5 volts. It is crucial not to allow the charging voltage to climb above 13.5 volts during the flash process. If the PCM flash process is interrupted or aborted for any reason, it must be restarted from the beginning. Furthermore, after successfully applying this TSB, it is not necessary to send DID-I or DID-A data.

Symptoms

Owners of affected 2025 Jeep Compass vehicles equipped with the 1.3L I4 Turbo MAIR DI ENG W/ESS E100 (Sales Code EYJ) may experience one or more of the following issues related to the Powertrain Control Module (PCM) software:

• The vehicle may exhibit a "P0607 - Control Module Performance" Diagnostic Trouble Code (DTC).
• The vehicle "will not start until the ignition is cycled for a second time." This means the engine may crank but not start on the first attempt, requiring the driver to turn the ignition off and then on again to successfully start the vehicle.
• The "Injection light is illuminated in the Instrument Panel Cluster (IPC)." This warning light indicates a potential issue with the fuel injection system or engine management.

These symptoms collectively point to an underlying problem with the 2025 Jeep Compass PCM software, which is addressed by TSB 18-057-25.

Fault Codes / DTCs

The primary Diagnostic Trouble Code (DTC) associated with this issue is:

Code	Description
P0607	Control Module Performance

Diagnosis and Trigger Conditions

Technicians will use a Scan Tool, such as wiTECH, along with diagnostic procedures from DealerCONNECT/Service Library, to verify system functionality. If the symptoms described above are present, or the P0607 DTC is found, the repair procedure outlined in TSB 18-057-25 should be followed. Any other DTCs or symptoms unrelated to this bulletin should be addressed separately before proceeding with the PCM software update.

Cause

The root cause of these symptoms and the P0607 DTC in the 2025 Jeep Compass is identified as an issue within the Powertrain Control Module (PCM) software. This software anomaly can lead to performance issues, starting difficulties, and trigger warning lights.

Repair Procedure Summary

The repair for this condition involves updating the 2025 Jeep Compass PCM software to the latest available version. The process is straightforward and typically involves the following steps:

1. Preparation: Before beginning, a battery charger must be connected to the vehicle to ensure the battery voltage remains stable between 13.2 and 13.5 volts throughout the programming process. This prevents potential issues from voltage drops.
2. Reprogramming: The technician will use the wiTECH Diagnostic Application to reprogram the Powertrain Control Module (PCM) with the most current software. If any issues arise during the flashing process, a ticket should be submitted to the Helpdesk for assistance.
3. DTC Clearing: After the PCM has been successfully reprogrammed, any Diagnostic Trouble Codes (DTCs) that may have been set in various modules due to the reprogramming process will be cleared using the wiTECH application.

This procedure is estimated to take approximately 0.2 hours of labor time.

Required Tools or Parts

The primary tool required to perform this software update is:

• wiTECH or Equivalent: A diagnostic scan tool capable of communicating with the vehicle's modules and performing software reprogramming.

No specific replacement parts are typically needed for this software-only repair.

Owner Action

If you own a 2025 Jeep Compass in the affected markets (primarily South America, but also NA, SA, EE, CH) and are experiencing a P0607 DTC, a no-start condition that requires cycling the ignition, or an illuminated injection light, you should contact your authorized Jeep dealership. Explain the symptoms you are experiencing and mention Technical Service Bulletin 18-057-25. The PCM software update is reimbursable under the provisions of the vehicle's warranty.
