WARNING: This should not be attempted without the vehicle
being in a safe area and suitably chocked. Failure to follow this
instruction may result in personal injury.
Without using the Jaguar approved diagnostic system or a scan
tool with system readiness capability, it will not be possible to
confirm when the adaptations are complete, unless P1111,
(system checks complete since last memory clear) is flagged. If
such equipment is not available, ALL the diagnostic monitors
will have to run to enable DTC P1111 to be flagged. In some US
states, this code is a requirem ent for annual emissions tests.
1. The dri v

ill enable the monitors to run,
but only after fuelling adaptations are complete.
