JaguarDrive Control Sub-System Faults

WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2015 Jaguar XKR-S, 2015 Jaguar XKR, 2015 Jaguar XK, 2014 Jaguar XKR-S, and 2014 Jaguar XKR. However, it is still accessible from the selected car via links, so may be relevant.

If a fault occurs in a sub-system, the driver is alerted by the illumination of a warning indicator and/or an appropriate message for that sub-system in the instrument cluster message center. No JaguarDrive control message will be shown when a failed sub-system displays its own message.

When a sub-system fault is present and the driver attempts to select a different JaguarDrive control mode or at the next ignition on cycle, a message WINTER MODE FAULT or DYNAMIC MODE FAULT will appear in the message center. This generally implies that the JaguarDrive control system has a fault, but only because a sub-system fault is preventing its operation. This message will be displayed once per ignition cycle, but is repeated if a further selection is made by the driver using the JaguarDrive control buttons or at the next ignition on cycle.

NOTE:

The message WINTER MODE FAULT or DYNAMIC MODE FAULT can also in very rare circumstances be generated by a fault in the JaguarDrive selector module.
It is not possible for the JaguarDrive selector module to cause any fault behavior (warning indicator illumination or message generation) in any of the sub-systems. Illumination of a sub-system warning indicator and/or a sub-system related message will never be associated with a JaguarDrive selector module or JaguarDrive control system fault.

The sub-system control modules can detect a fault with the CAN bus signal from the JaguarDrive selector module. If a fault in the JaguarDrive control system is detected, the sub-system control modules will operate in the special modes off setting. The sub-system control modules will record a fault code for a failure of the JaguarDrive control CAN signal. These faults can be retrieved using the Jaguar approved diagnostic tool and will provide useful information to indicate investigation of the JaguarDrive selector module or the CAN bus network.
