Vehicle Condition Monitor (VCM)

VEHICLE CONDITION MONITOR (VCM)

INTRODUCTION

The Vehicle Condition Monitor (VCM) information is displayed on the Odometer/VCM/Trip Computer display panel located below the tachometer and speedometer.

The condition of the vehicle is constantly monitored for operating faults which, if found, are highlighted by the illumination of certain warning lamps. By pressing the VCM button located on the trip computer panel the relevant fault message will be displayed. In the event that more than one fault has occurred, the display panel will cycle between messages, pausing for two seconds at each one, (except for Engine Management faults, see 'Fault Codes (Check Engine)' below).

To enable the trip computer information to be displayed, the button marked 'CLEAR' provides a means of extinguishing any VCM message present on the written display. Pressing the VCM button when a fault exists will override any trip computer messages and re-display the relevant VCM fault symbol.

FAULT CODES (CHECK ENGINE)

In the event of an engine management fault occurring the 'Check Engine' warning lamp will illuminate. Additional information can be displayed by pressing the VCM button located on the trip computer panel. When a fault has been signalled the likely area responsible for the malfunction can be indicated when the vehicle is stationary. Switch 'OFF' the ignition, wait at least 5 seconds, then turn the ignition switch to position 'II' (do not start the engine). Press the VCM button, this action will cause the VCM / trip computer display to illuminate the applicable fault code.

Note: Federal Specification: All fault codes are latched, and when triggered, stored in the Engine Control Module (ECM) memory. In addition the 'Check Eng' lamp is illuminated, and will remain illuminated (when the ignition is switched 'ON') until the faults are rectified and the ECM memory cleared by the Jaguar Diagnostic System (JDS) or by grounding the relevant ECM pin.

Note: Euro-catalyst and non-catalyst specifications are not latched. This implies that the 'Check Eng' lamp will be extinguished after switching the ignition 'OFF' if the fault is not triggered again. However, the code will still be stored in the ECM memory and can be accessed by dealer personnel, thus ensuring that intermittent faults will be recorded.

Fault Codes are listed on the next page. The fault codes are displayed individually in numerical order. The next code is only displayed when the first one is rectified and I or cleared from the ECM memory.
