Symptoms

Owners of 2021-2023 Jeep Compass vehicles may experience a specific issue where "The rear seat belt buzzer stays on after the passenger leaves the vehicle." This persistent chime can be distracting and indicates a potential fault in the vehicle's electrical system.

This symptom specifically applies to Jeep Compass models manufactured for the India market, equipped with the 10.25-inch TFT Color Display, identified by Sales Code JAU.

Fault Codes

When diagnosing this issue, technicians are instructed to use a specific failure code:

Code	Description
CC	Customer Concern

This failure code, CC, must be used in conjunction with Technical Service Bulletin 08-062-25 if the customer's reported symptom matches the described condition. When utilizing this code, the 3C's (customer's concern, cause, and correction) must be documented for processing the Technical Service Bulletin flash/reprogramming conditions.

Diagnosis

To diagnose the Jeep Compass rear seat belt buzzer issue, technicians will use a Scan Tool, such as wiTECH, along with the appropriate Diagnostic Procedures available in DealerCONNECT/Service Library. The primary goal is to verify that all related systems are functioning correctly.

If Diagnostic Trouble Codes (DTCs) or other symptom conditions, beyond the persistent buzzer, are present, these should be recorded and addressed as necessary before proceeding with the software update outlined in TSB 08-062-25. If the customer's concern directly matches the symptom described in the bulletin, the repair procedure can be initiated.
