Symptoms

Owners of affected 2022 Jeep Compass vehicles may experience one or more of the following symptoms:

• A warning message displayed on the Instrument Panel Cluster (IPC) stating: "Auto Hold Unavailable Service Required."
• The IPC "Hold" indicator illuminates on occasion.
• The Engine Stop/Start (ESS) system becomes inoperative.

Cause of the Issue

The root cause of the described symptoms is identified as a software anomaly within the Anti-Lock Brake System (ABS) module. An update to the ABS software is necessary to correct these malfunctions and restore proper system functionality in the 2022 Jeep Compass.

Diagnosis for Technicians

Before performing the repair, technicians are instructed to use a wiTECH scan tool along with appropriate Diagnostic Procedures from the DealerCONNECT/Service Library. They must verify that all related systems are functioning as designed. If any Diagnostic Trouble Codes (DTCs) or symptom conditions other than those listed in the TSB are present, these should be recorded and addressed before proceeding with the bulletin's repair procedure. The repair procedure should only be performed if the customer's reported symptoms match those identified in this bulletin.

Repair Procedure Summary

The repair for this issue involves reprogramming the ABS module with the latest available software. The process is straightforward and typically takes 0.4 hours of labor under Labor Operation No: 18-19-10-AM.

1. Battery Stabilization: A battery charger must be connected to maintain the battery voltage between 13.2 and 13.5 volts throughout the flash process. This ensures stable power delivery during the software update.
2. ABS Reprogramming: The ABS module is reprogrammed using the wiTECH Diagnostic Application. Detailed instructions are available within the application's "HELP" tab.
3. DTC Clearance: After reprogramming, any Diagnostic Trouble Codes (DTCs) that may have been set in any module due to the reprogramming process must be cleared. The wiTECH application will automatically present these DTCs for clearance.
4. Post-Flash Procedure: Technicians must perform the ECU Replace/Post Flash Procedure routine found under "Misc Functions" in the wiTECH application.

Required Tools and Parts

The primary tool required for this repair is a wiTECH or Equivalent diagnostic scan tool, which is used to perform the ABS module reprogramming and diagnostic checks.

Important Notes for the Repair

Technicians are advised to ensure that battery voltage does not drop below 13.2 volts or climb above 13.5 volts during the flash process. If the flash process is interrupted or aborted for any reason, it must be restarted from the beginning. For warranty claims related to this TSB, the dealer must use failure code CC (Customer Concern). When using this failure code, the 3C's (customer's concern, cause, and correction) must be provided for processing the Technical Service Bulletin flash/reprogramming conditions.
