OBD1 pre-96

READING FAULT CODES (USA only)
The Engine Control Module (ECM) is capable of storing fault codes. For U.S. vehicles, these fault codes may be read by switching the ignition switch to position II and observing the fuel injection fault display unit, which is located underneath the right hand front seat, adjacent to the ECM.



NOTE: Image shows display unit with trim removed.

If no codes are present, the display will appear blank. A constantly lit Check Engine warning light indicates that a fault is present.

  1. Put the ignition switch in position 0 and wait till the load relay drops out.
  2. Put the ignition switch in position II. The display will be blank if no other faults exist. If other codes exist, the next fault code will be displayed.
  3. If multiple faults exist, repeat steps 1 through 3 until all faults are cleared.

Code 02 indicates that the ECM has just been reconnected. Switch the ignition switch to position II to clear code 02.

For non-U.S. vehicles (not equipped with a fuel injection fault display), the Lucas diagnostic equipment, part number 60600965, is recommended for reading fault codes.

How to Clear Diagnostic Trouble Codes

CLEARING FAULT CODES (USA only)
When a fault has been corrected, the fault code must be cleared. This is done by performing the following procedure:

  1. Put the ignition switch in position II.
  2. Disconnect the Data Link Connector (DLC) , which is located behind R/H side of dash, and wait 5 seconds. Reconnect data link connector.
  3. Put the ignition switch in position 0 and wait till the load relay drops out.
  4. Put the ignition switch in position II. The display will be blank if no other faults exist. If other codes exist, the next fault code will be displayed.
  5. If multiple faults exist, repeat steps 1 through 4 until all faults are cleared. NOTE : Code 02 indicates that the Engine Control Module (ECM) has just been reconnected. Switch the ignition switch to position II to clear code 02.

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
.
