Principles Of Operation: Diagnostics: Notes
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.
The JaguarDrive control system relies on the correct functionality of the sub-systems. If one of the sub-systems develops a fault, the JaguarDrive control system will not function, even though the fault is not in the JaguarDrive control system.
The JaguarDrive selector module and the mode buttons should only be investigated if there are no apparent faults in any of the sub-systems. If a fault in a sub-system is subsequently corrected, the JaguarDrive control system will function normally after an engine on and off cycle.
