1996 - up OBD2 Fault Codes

With Generic OBD II Scan Tool

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 ).

The DLC is located at the passenger side footwell.

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 manufacture does not provide any other information on How to Pull Codes, Trouble Code Descriptions, Diagnosis and Testing of Trouble Codes or How to Clear codes.

DIAGNOSTIC TROUBLE CODES

*Codes* are used to identify the 4 Oxygen Sensors.
A = Bank A of the engine. Cylinder #1 is located on Engine Bank A.
B = Bank B of the engine.
U = Upstream of the Catalytic Converter.
D = Downstream of the Catalytic Converter.

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