2021 Jeep Compass CVPM Software Update for Camera Issues

Owners of 2021 Jeep Compass vehicles may experience various issues related to the Central Vision Processing Module (CVPM) and Surround View Camera System. These problems, which can include warning lights and camera malfunctions, are addressed by Technical Service Bulletin (TSB) 08-167-24. This bulletin outlines a software update designed to resolve these concerns and restore proper functionality.

The 2021 Jeep Compass CVPM software update is applicable to vehicles equipped with the Surround View Camera System (Sales Code XAK). This update ensures that the CVPM operates correctly, preventing the display of error messages and restoring camera features.

Symptoms

Customers may notice a Malfunction Indicator Lamp (MIL) illuminating on the dashboard. In addition to this warning light, drivers might observe several other symptoms indicating a problem with the CVPM or camera system. These include:

• "Top-down camera view is blank when camera view is selected in the radio menu."
• "Odometer is flashing."
• "No backup camera gridlines when vehicle transmission is in reverse."

Fault Codes / DTCs

When these symptoms occur, a diagnostic scan of the vehicle's systems will typically reveal specific Diagnostic Trouble Codes (DTCs) stored in the vehicle's computer. The TSB identifies the following codes:

Code	Description
B2286-00	Calibration Not Learned - Lost Calibration
B223B-00	Vehicle Configuration Mismatch

Diagnosis

To accurately diagnose the issues described in TSB 08-167-24, technicians will use a diagnostic scan tool such as wiTECH. This tool helps verify that all related systems are functioning as intended. If any of the listed DTCs or symptoms are present, and no other unrelated issues are found, the repair procedure outlined in this bulletin should be followed.

Important Warnings for Technicians

During the repair process, specific precautions must be taken to ensure the software update is successful and to prevent damage to the vehicle's electrical system:

• "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."
• "If this flash process is interrupted/aborted, the flash should be restarted."

Repair Procedure Summary

The primary repair for the 2021 Jeep Compass CVPM software update involves updating the Central Vision Processing Module (CVPM) with the latest available software. The general steps are as follows:

1. Prepare the Vehicle: Connect a battery charger to maintain stable voltage between 13.2 and 13.5 volts throughout the process. If the flash is interrupted, it must be restarted.
2. Reprogram CVPM: Use the wiTECH Diagnostic Application to reprogram the CVPM with the most current software. If any issues arise during this step, a ticket should be submitted to the Helpdesk.
3. Perform PROXI Alignment: Execute the PROXI Configuration Alignment routine, which is found in the Guided Diagnostics menu of the wiTECH application.
4. Clear DTCs: Clear all Diagnostic Trouble Codes that may have been set in any module due to the reprogramming. The wiTECH application will automatically present these DTCs for clearing after the flash is complete.

This procedure, identified by Labor Operation Number 18-19-90-94, typically takes 1.5 hours to complete.

Required Tools or Parts

The main tool required for this service is the wiTECH diagnostic system or an equivalent diagnostic tool capable of performing module reprogramming and PROXI Configuration Alignment.

Owner Action

If your 2021 Jeep Compass is exhibiting any of the described symptoms, such as MIL illumination, a blank top-down camera view, a flashing odometer, or missing backup camera gridlines, you should schedule an appointment with an authorized Jeep dealership. The 2021 Jeep Compass CVPM software update is covered under warranty provisions, meaning there should be no cost to the owner for this repair.
