ECM Connector Identification

WARNING: This page is about a different car, the 2002 Land Rover Range Rover and 2002 Land Rover Discovery. However, it is still accessible from the selected car via links, so may be relevant.

On Discovery, ECM is located on the right side "A" post behind the front passenger kick panel. On Range Rover, the ECM is mounted in a plastic E-box located on the left side of engine compartment firewall. ECM is cooled by a dedicated fan, which provides cabin air to the plastic E-box maintaining a suitable environment for ECM operation. The operating temperature of the ECM is monitored by an internal temperature sensor. On all models, the ECM has 5 independent connectors totalling 134 pins. See Fig 1 and Fig 2 . See ECM CONNECTOR IDENTIFICATION table.
