Evaporative Emissions: Other Jaguar X-type I

Flow check monitor drive cycle conditions (non-Federal)

Note. These conditions must be satisfied before the test is commenced.

This drive cycle should be performed following rectification work on the system.

1. Make sure the fuel tank is between one quarter and three quarters full. (Adding fuel will increase vapor generation; the diagnostic will not run if the vapor concentration is too great).
2. Make sure the ambient air temperature is above -5°C (23°F).

Flow check monitor drive cycle (non-Federal)

1. Drive the vehicle for a minimum of 15 minutes, avoiding severe or excessive fuel movement.
2. Avoiding excessive fuel movement, gently bring the vehicle to rest. (Coast to a stop).
3. Allow the vehicle to idle for two minutes.

Full Evaporative system monitor drive cycle conditions

Note. These conditions must be satisfied before the test is commenced.

1. Make sure the fuel filler cap is correctly fitted. (Minimum three clicks).
2. Clear the DTCs. (Perform a code clear, even if no codes are present. This will reset TIDs).
3. Make sure the fuel tank is between one quarter and three quarters full. (Adding fuel will increase vapor generation; the diagnostic will not run if the vapor concentration is too great).
4. Drive the vehicle for a minimum of two minutes, and until fully warm. (Temperature gauge just below mid-point).
5. Make sure that the purge valve is operating, either by touch, sound, or using datalogger. (Purge vapor management valve-duty cycle). If the purge is not active, perform the "Drive cycle for green engine control module (ECM)" in this section.

Full Evaporative system monitor drive cycle

1. Drive the vehicle to a suitable road where the test can be carried out, switch off the ignition.
2. Leave the ignition switched off for 30 seconds.
3. Restart the engine, accelerate briskly to 80 Kilometres per hour (50 miles per hour), making sure that the engine speed reaches at least 3500 RPM for a minimum of five seconds.

40 thou and 20 thou tests using no additional equipment

The test procedure and conditions are as for the Jaguar approved diagnostic system or GDS510, but no confirmation of the test having run is possible without the use of one of these instruments. The DTC will be set if the fault still exists, but the possibility exists that the conditions for the test to run may not have been met, in which case, the DTC may not be set until the owner reproduces the conditions in which the fault originally occurred.

Drive cycle for "green" ECM

1. To enable the ECM to re-learn fuelling adaptions.

Note. This procedure should be performed whenever the vehicle battery has been disconnected.

Due to component tolerance and wear during the normal running of a vehicle, fuelling and air requirements for an engine will vary over time. The ECM has the ability to adjust for this variation by "learning" the level of compensation that is required. (These compensation values are referred to as adaptions)

If the vehicle battery is disconnected, all adaptions held within the ECM will be lost (ie, set to Zero) The ECM is then referred to as "green". To enable the vehicle to function correctly, the ECM must "relearn" these adaptions.

There are four areas or sites that need to be relearnt.

1. Allow the vehicle to idle until fully warm. (Temperature gauge just below mid-point).
2. Allow to idle for a further three minutes, minimum.
3. Drive the vehicle with the air conditioning OFF on a level road using a constant throttle, or speed control if fitted, for at least one minute in the following gears, at the stated engine speeds for each of the sites below.

The vehicle speed is for guidance only. DO NOT use the vehicle speed as the target to set adaptions.

Bring the vehicle to rest, allow to idle for one minute.

If sufficient adaptions have occurred, the Evaporative valve should now be operating. This can be verified manually by either touching or listening to the valve. By touching the Evaporative valve, it should be possible to feel the valve switching. Listening to the Evaporative valve is best done using a workshop stethoscope, through which it should be possible to hear the valve operating.
