Diagnostic Monitor Completion

WARNING: This page is about a different car, the 2002 Jaguar XKR and 2002 Jaguar XK8. However, it is still accessible from the selected car via links, so may be relevant.

The drive cycles detailed here will enable the monitors to run, but only after fuelling adaptations are complete.

During the drive cycle, drive gently, avoiding hard acceleration, braking or cornering and rough roads.
- Drive at 84 to 97 kph (52 to 60 mph) for 40 seconds.
- Accelerate to 113 kph (70 mph).
- Close the throttle, (ideally at the start of a descent) continue with closed throttle for 10 seconds. (* Fuel cut)
- Drive at 56 to 64 kph (35 to 40 mph), holding the throttle as steady as possible, on a flat level road for 30 seconds minimum.
