Programming Drive Cycle (Fuelling Adaptations)
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.
NOTE:
Ensure engine is at normal operating temperature.
Using the Jaguar Portable Diagnostic Unit (PDU) scan tool or a generic scan tool connected to the 16-pin Data Link Connector (DLC), measure the mass air flow rate (most generic scan tools should be capable of reading this parameter). See PROGRAMMING DRIVE CYCLE table. Depending on road conditions and dealer location, it may be difficult to achieve the road speeds 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 reaching the air flow figure stationery in Drive.
