2023-2026 Jeep Compass Collision Warning Light TSB

Important Market Applicability Note

It is crucial for owners in the United States to be aware that Technical Service Bulletin (TSB) 08-364-25 explicitly states that it applies to the South America market. This means that while the symptoms and repair described are relevant, this specific bulletin is not intended for vehicles sold in the US market. If you are experiencing these symptoms in a US-market vehicle, your dealer may need to refer to different diagnostic procedures or bulletins.

Symptoms

Owners of affected 2023-2026 Jeep Compass vehicles may experience a Malfunction Indicator Lamp (MIL) illuminating on the instrument cluster. The primary symptom is the illumination of the "collision warning light and lane-keeping light" on the Instrument Panel Cluster (IPC) specifically "when the steering wheel is turned." This indicates a potential issue with the vehicle's active safety systems. There are no other abnormal behaviors reported in the vehicle due to this concern, focusing solely on the warning lights and the associated diagnostic trouble codes.

Fault Codes / DTCs

When the "Jeep Compass collision warning light" or lane-keeping light illuminates, one or more of the following Diagnostic Trouble Codes (DTCs) may be set:

• B178F-15: Turn Signal Switch-circuit Short To Battery Or Open.
• B1051-15: Column Switch Module Turnlights - Circuit Short To Battery Or Open.

These codes point to an electrical issue within the turn signal switch or column switch module.

Diagnosis

To properly diagnose this concern, technicians are instructed to use a Scan Tool, such as wiTECH or an equivalent diagnostic system. They should follow the appropriate Diagnostic Procedures available in DealerCONNECT/Service Library to verify that all related systems are functioning as designed. If any DTCs or symptom conditions other than those described in TSB 08-364-25 are present, these should be recorded and addressed before proceeding with the bulletin's repair.

Repair Procedure Summary

The repair outlined in TSB 08-364-25 addresses the manufacturing issue causing the illuminated warning lights and associated DTCs. The procedure involves the following steps:

1. Inspect Electrical Connectors: Technicians must first check the electrical connectors and terminations of both the turn signal lever and the Body Control Module (BCM). If these connections are found to be in compliance, the next step is to replace the signal lever.
2. Replace Signal Lever Assembly: The faulty signal lever assembly is to be replaced. Detailed service procedures for this replacement can be found in the DealerCONNECT/Service Library under reference 5550A12 - Comando Indicadores de Direção - Remoção/Recolocação para Veículos com Air Bag.
3. Clear DTCs: After the replacement is complete, all stored Diagnostic Trouble Codes must be cleared from the vehicle's system.

It is important to note that after applying this TSB, it is not necessary to send DID-I or DID-A data.
