2024 Jeep Compass PCM Software Update for DTC P0607

Symptoms

Owners of affected 2024 Jeep Compass vehicles may experience specific issues related to the Powertrain Control Module (PCM). These symptoms include the vehicle failing to start until the ignition is cycled a second time. Additionally, the "Injection light" may illuminate in the Instrument Panel Cluster (IPC).

Fault Codes / DTCs

Technicians diagnosing the issue on a 2024 Jeep Compass may find the following Diagnostic Trouble Code (DTC):

• P0607 - Control Module Performance

Diagnosis

To properly diagnose the issue, technicians should utilize a Scan Tool (wiTECH) in conjunction with the Diagnostic Procedures available in DealerCONNECT/Service Library. It is crucial to verify that all related systems are functioning as designed. If any DTCs or symptom conditions, other than those listed in this bulletin, are present, they must be recorded and repaired before proceeding with the PCM software update outlined in TSB 18-059-25.

Repair Procedure Summary

This bulletin, TSB 18-059-25, outlines a procedure to resolve the PCM software issue by reprogramming the module with the latest available software. The process involves several key steps:

1. Battery Preparation: A battery charger must be connected to the vehicle to ensure the battery voltage remains between 13.2 and 13.5 volts throughout the reprogramming process. It is critical that the voltage does not drop below 13.2 volts or climb above 13.5 volts.
2. PCM Reprogramming: The Powertrain Control Module (PCM) is then reprogrammed using the latest software via the wiTECH Diagnostic Application. If the flash process is interrupted or aborted for any reason, it must be restarted from the beginning.
3. DTC Clearing: After successful reprogramming, any Diagnostic Trouble Codes (DTCs) that may have been set in other modules due to the reprogramming process will be automatically presented by the wiTECH application and must be cleared.

Required Tools or Parts

To perform the repair outlined in this technical service bulletin, technicians will need:

• wiTECH or Equivalent Scan Tool: Essential for diagnosis and reprogramming the PCM.
• Battery Charger: Required to maintain stable battery voltage during the flash process.
