2021-2025 Jeep Compass DRL Inoperative TSB 08-236-25

Important Market Information

It is crucial for owners to note that TSB 08-236-25 specifically applies to the Enlarged Europe market for the 2021-2025 Jeep Compass. This bulletin is not applicable to vehicles built for the US market. Owners outside of the Enlarged Europe market experiencing similar symptoms should consult their local dealership for region-specific guidance.

Symptoms

Owners of affected 2021-2025 Jeep Compass vehicles in the Enlarged Europe market may experience a specific issue with their Daytime Running Lamps (DRL). The primary symptom is that the "DRL are inoperative only after the Body Control Module (BCM) has been flash updated or replaced."

This means that the DRLs, which are designed to enhance visibility during daytime driving, will not illuminate or function as expected. The Jeep Compass DRL inoperative condition only manifests after a software update is performed on the BCM, or if the BCM itself is replaced by a technician. Prior to these events, the DRLs would have functioned normally.

Cause of the DRL Inoperative Condition

The root cause of the Jeep Compass DRL inoperative issue is identified as BCM software. Specifically, the problem arises due to a Body Control Module (BCM) Memory Layout change. This change occurs when the BCM is updated to the latest software level or when a new BCM is installed in the vehicle.

Stellantis clarifies that this is an expected behavior resulting from the software architecture and is not indicative of a defect or a fault in the BCM itself. The new memory layout requires a specific post-update procedure to correctly configure the DRL functionality.

Repair Procedure Summary

To resolve the Jeep Compass DRL inoperative condition, technicians must perform a specific routine using the wiTECH diagnostic tool. This procedure is designed to correctly configure the DRLs after a BCM software update or replacement.

The routine is called the "Combine DRL and Stop Light routine." Technicians can access this function within the wiTECH system by navigating through the following menu path: BCM -> Misc Functions -> Combine DRL and Stop Light. Executing this routine will change a specific "Set" parameter within the BCM software. This parameter adjustment is necessary to properly separate the functionality of the Daytime Running Lamps from the stop lights, thereby restoring the DRLs to their intended operational state.

This is a dealer-level repair that requires specialized diagnostic equipment and trained personnel. Owners experiencing this issue should schedule an appointment with an authorized Jeep service center.
