Land Rover Engine Codes

When an OBD-II fault occurs in Land Rover's Generic Engine Management System (GEMS), the Malfunction Indicator Lamp (MIL) is illuminated. GEMS Diagnostic Trouble Codes (DTC ) are stored in the Engine Control Module (ECM ) and may be retrieved by connecting a suitable OBD II Scan Tool or the Land Rover TestBook Electronic Tester to the Data Link Connector (DLC ). DTC's can only be Extracted, Diagnosed and Cleared by the TestBook Diagnostic Unit, a required special tool , or an appropriate after market equivalent.

All information regarding DTC's for this model is contained within the Land Rover TestBook Diagnostic Unit. The manufacturer does not provide any other information on pulling codes, descriptions, diagnosis, clear codes, etc.

*Codes* are used to identify the 4 Oxygen Sensors.

Example: A D = Oxygen Sensor Engine Bank A, Downstream of Catalytic Converter.
