Jaguar vehicles obd1 code retrieval

For Jaguar vehicles with obd1 codes (made before 1995 or 1993), testing the check engine lights in your dash to get the code is simple. All you do is locate the Vehicle Condition Monitor (VCM) button in the dash panel sitting below the tachometer and speedometer. The procedure begins by turning the key off and waiting for 5 seconds then turning the ignition key to position 2 without starting the engine. When you press the VCM button, codes will start to display in your dash panel.

Clearing the codes can be done by turning the key off and removing the battery negative terminal for 30 seconds and reconnect.
