Rear Differential Control Module (RDCM) Connector Checks

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The RDCM connector may be incorrectly connected or insecure due to the wiring harness being tapped too close to the connector
  1. Inspect the RDCM wiring harness connector(s) for correct and secure connection. Check whether the connector(s) are secure and flush with the RDCM. See the image below of a correctly and incorrectly located connector

  2. If a connector is not flush with the RDCM, remove the connector and check the condition of the terminals within the connector. Have the pins been pulled out or damaged resulting in poor connectivity? See the image below
