2022 Jeep Compass False Park Assist Warning TSB 08-147-24

Owners of the 2022 Jeep Compass equipped with the P&P Park and Unpark Assist System (Sales Code XPK) and Front Fascia Parts Module (Sales Code X8W) may encounter a specific issue related to their vehicle's park assist system. This concern is detailed in Technical Service Bulletin (TSB) 08-147-24, issued on June 26, 2024, by Stellantis.

The primary symptom is a 2022 Jeep Compass false park assist warning appearing on the dashboard. This happens even when there are no actual obstacles in front of the vehicle. The root cause has been identified as a software issue within the Park Assist Module (PAM).

Symptoms

The most common symptom reported by owners is a persistent or intermittent warning message related to the front park assist system. Specifically, you might see a "False front park assist warning when no obstacle present in front of vehicle" message. This can be distracting and may lead to unnecessary caution or confusion while driving or parking.

Diagnosis / Trigger Conditions

To diagnose this specific issue, technicians will use a scan tool, such as wiTECH, in conjunction with the diagnostic procedures available in DealerCONNECT/Service Library. The goal is to verify that all related systems are functioning as intended.

It's important to note that if any Diagnostic Trouble Codes (DTCs) or other symptom conditions are present beyond the false park assist warning, these should be recorded and addressed before proceeding with the TSB 08-147-24 repair. The bulletin specifically targets the "False front park assist warning when no obstacle present in front of vehicle" symptom caused by PAM software.

Repair Procedure Summary

The repair for the 2022 Jeep Compass false park assist warning involves reprogramming the Park Assist Module (PAM) with the latest available software. This process is straightforward but requires specific attention to detail:

1. Battery Charger Connection: Before starting, a battery charger must be connected to the vehicle. This is crucial to ensure the battery voltage remains between 13.2 and 13.5 volts throughout the flash process. Maintaining stable voltage prevents interruptions or potential damage during the software update.
2. PAM Reprogramming: The technician will reprogram the PAM using the wiTECH Diagnostic Application. If any issues occur during the flashing, the process should be restarted.
3. DTC Clearing: After successful reprogramming, all Diagnostic Trouble Codes (DTCs) that may have been set in any module due to the reprogramming process will be cleared using the wiTECH application.
4. System Verification: Finally, the park assist system's proper operation must be confirmed. This is typically done by using traffic cones to ensure that the system detects actual obstacles correctly and that no false alerts are generated.

If, after these steps, the park assist system is still not operating normally, further diagnosis will be required.

Required Tools or Parts

The primary tool required for this repair is the wiTECH diagnostic system or an equivalent scan tool capable of performing module reprogramming.

Important Warnings

When performing the software update for the 2022 Jeep Compass false park assist warning, technicians must adhere to critical voltage requirements. Install a battery charger to ensure battery voltage does not drop below 13.2 volts. Do not allow the charging voltage to climb above 13.5 volts during the flash process. An unstable voltage can lead to an interrupted or aborted flash, in which case the flash process must be restarted.

If your 2022 Jeep Compass is exhibiting a "False front park assist warning when no obstacle present in front of vehicle," you should schedule an appointment with your authorized Jeep dealership. The repair, which involves updating the PAM software, is reimbursable within the provisions of your vehicle's warranty.
