DTCs P1000/P1111 Conditions for adaptation
Fuelling Adaptations Drive Cycle
•
NOTE: Make sure the engine is at normal operating
temperature. (75°C, 167°F) 1.
Whenever the battery is disconnected, the Engine Control
Module (ECM) adaptations are reset to a "green" ECM
condition. In this condition, certain functions of the ECM are
inhibited, and the ECM must "r elearn" these functions. To
enable the ECM to do this, the vehicle will have to perform
some maneuvres which it may, or may not, do during a normal
road test. The routine in this pr ocedure should be carried out at
Pre-Delivery Inspection, and after any emissions related
rectification work involving the disconnection of the battery.
2. When the DTCs relating to a rectified concern are cleared,
P1000 (system checks not complete since last memory clear)
will be flagged. This DTC does no t indicate a failure, just that
diagnostic drive cycles need to be performed. The vehicle's on-
board diagnostic system will confirm that all the diagnostic
drive cycles are complete by flagging P1111, (system checks
complete since last memory clear)
1. Make sure these conditions are checked and corrected, if
necessary, before carrying ou t the adaptation procedure.

Either
the Jaguar approved diagnostic system (where
available), or a scan tool should be connected to measure the
Mass Air Flow rate. Most generi c scan tools should be capable
of reading this parameter.
Depending on road conditions and dealer location, it may be
difficult to achieve the road sp eeds necessary to reach the air
flow indicated. It is possible to reach these air flow figures by
inducing a load on the vehicle, (making use of hills, using a
lower gear ratio, etc) or, if no alternative is possible, by
restraining the vehicle and re aching the air flow figure
