Diagnosis

The root cause for the Malfunction Indicator Lamp (MIL) illumination and the P2601-00 fault code in the 2025 Jeep Compass is identified as an issue with the Powertrain Control Module (PCM) software. To diagnose the issue, a scan tool such as wiTECH is used to confirm the presence of the DTC and ensure no other related system issues are present. If the customer's concern matches the symptoms described and the 2025 Jeep Compass DTC P2601-00 is present, the repair procedure outlined in TSB 18-096-25 should be followed.

Repair Procedure Summary

The repair for the 2025 Jeep Compass DTC P2601-00 involves updating the Powertrain Control Module (PCM) software to the latest available version. The process is as follows:

1. Prepare the Vehicle: Install a battery charger to maintain the vehicle's battery voltage between 13.2 and 13.5 volts throughout the flash process. This prevents interruptions or damage during the software update.
2. Reprogram PCM: Use the wiTECH Diagnostic Application to reprogram the PCM with the most current software. If the flash process is interrupted, it must be restarted.
3. Clear DTCs: After reprogramming, clear all Diagnostic Trouble Codes that may have been set in any module. The wiTECH application will automatically present these DTCs for clearing.
4. Verify HCP Software: Ensure the Hybrid Control Processor (HCP) is also programmed with its latest available software. Technicians should refer to other applicable service bulletins for detailed procedures and labor times related to updating the HCP software.

Required Tools or Parts

To perform this software update, technicians will need:

• wiTECH or Equivalent: A diagnostic scan tool capable of performing software flashes.
• Battery Charger: To maintain stable voltage during the reprogramming process.
