2023-2025 Jeep Compass C14A4-00 ACC Sensor Adjustment

Symptoms of the C14A4-00 ACC Sensor Adjustment Issue

Owners of 2023-2025 Jeep Compass vehicles may observe a specific warning message in the instrument cluster related to the Forward Collision Warning (FCW) and Adaptive Cruise Control (ACC) systems. The primary symptom is the display of a "Sensor Adjustment Required Set In Adaptive Cruise Control Module (ACC)" message. This warning is often accompanied by the diagnostic trouble code (DTC) C14A4-00.

The issue, as noted in Stellantis TSB S2523000022 Rev. A, is particularly prevalent in high gusty or crosswind environments. If you experience this warning, especially during windy weather, it's important to have your vehicle inspected.

Fault Codes (DTCs)

The primary diagnostic trouble code associated with this issue is:

• C14A4-00: Sensor Adjustment Required Set In Adaptive Cruise Control Module (ACC)

This code indicates that the Adaptive Cruise Control module requires adjustment or has detected a condition preventing proper operation. The presence of this DTC, especially alongside the "Sensor Adjustment Required Set In Adaptive Cruise Control Module (ACC)" message, points to the specific problem addressed by TSB S2523000022 Rev. A.

Diagnosis and Trigger Conditions

The manufacturer notes that the condition mainly occurs in high gusty or crosswind environments. When diagnosing the Jeep Compass C14A4-00 issue, technicians are advised to discuss the environmental conditions with the owner to understand when the "Forward Collision Warning / Adaptive Cruise Control (FCW/ACC)" cluster warning and DTC C14A4-00 occurs.

Key diagnostic steps involve:

• ACC Bracket Inspection: Confirm that the ACC bracket is not damaged. Damage to this bracket could affect the sensor's alignment and function.
• Module Seating Verification: Verify that the Adaptive Cruise Control module is fully and securely snapped into its bracket. A loose or improperly seated module can lead to intermittent faults.
• General Vehicle Inspection: Perform a close inspection of the vehicle for any signs of accident damage, or other damaged or loose parts that might impact the ACC system's performance or mounting.

If the condition consistently appears in windy or gusty weather, engineering is aware of these customer complaints and is currently investigating the root cause. This suggests that while immediate physical checks are necessary, there might be an underlying design or calibration aspect under review.
