Understanding the Door Ajar Light Issue

Owners of various 2021-2025 Jeep, RAM, and Dodge vehicles may experience a persistent "Door Ajar Light On With Door(s) Closed" condition.

This manufacturer communication, identified as S2423000024 Rev. B, provides guidance for technicians to diagnose and resolve this specific concern, which is set to be released in September 2024.

The primary symptom is the "Door Ajar Light On With Door(s) Closed" message appearing on the instrument cluster, despite all doors being properly latched. Technicians investigating this issue may or may not find specific diagnostic trouble codes (DTCs) related to the "Door Ajar Circuits."

Analysis of parts returned for this issue has shown that many latches are replaced without any underlying fault. This bulletin aims to provide additional repair information to prevent unnecessary part replacements. For example, if a Jeep Compass door ajar light remains on, technicians should follow these steps in conjunction with any existing side door latch DTC diagnostic procedures.

Repair Procedure Summary

The repair process for a persistent "Door Ajar Light On With Door(s) Closed" involves a systematic inspection of the door latch circuit components:

1. Wiring and Connections Check: Verify that all wiring and electrical connections are correctly attached and routed. Ensure there are no visible signs of damage or improper installation.
2. Harness Connector Review: Inspect the harness connector associated with the door latch. Confirm it is properly and fully seated. Technicians should push on the connector to ensure it clicks into place, indicating a secure connection.
3. Pin Verification: If the connector does not fully seat after being pushed, it should be removed. The pins within the connector should then be carefully inspected for any damage, bending, or corrosion. If damaged pins are found, the connector must be replaced.
4. Side Door Latch Replacement: If all the above steps have been performed and the "Door Ajar Light On With Door(s) Closed" condition or Jeep Compass door ajar light issue persists, the side door latch itself should be replaced as a final step.

After completing any repair, the functionality of the side door latch must be validated. This involves performing several open and close cycles of the door to confirm the light now operates correctly. Technicians are required to document the specific issue found and the corrective action taken to resolve the customer's concern.
