Drive Cycle for 40 thou leak test
Drive Cycle for 20 thou leak test (2001 my on only)
1. Make sure the "conditions
for ad
aptation" detailed at the start
of this section are met.
1. Avoiding high engine load s, drive the vehicle steadily
between 48 and 89 kph (30 and 55 mph) for 15 to 20
minutes after starting the engine. (Depending on the
amount of fuel vapor gene rated, the test may take
longer than this).
2. Where possible, avoid body roll to minimise fuel movement.
3. If the scan tool being used is able to read TIDs, check
TID 08 in mode 6. If the test has not completed, this
TID will display "0". Any other value indicates that
the test has successfully completed.
4. If the test has not completed, the drive cycle must be repeated.
5. If the scan tool being used is not able to read TIDs, the only way to confirm that the test has run is to
check for P1111 after running the 20 thou test, where
applicable.
1. This test needs to be completed within 50 minutes of starting
the engine from cold. It should be run following the 40 thou
test.
1. Continue driving the vehi cle steadily between 48 and
89 kph, (30 and 55 mph) avoiding high engine loads
for a further 15 minutes.
2. Avoiding excessive fuel movement, bring the vehicle to rest.
3. Allow to idle for two minutes.
4. Provided the vapor conditions are suitable, the test will complete.
5. If the scan tool being used is able to read TIDs, check
TID 06 in mode 6. If the test has not completed, this
TID will display "0". Any other value indicates that
the test has successfully completed.
6. If the test has not completed, the drive cycle must be repeated.
7. Check for DTCs. P1111 will be flagged if all monitors have run.
8. Leak check drive cycles will only normally be necessary if an Evaporative Emissions related DTC is
flagged.
9. Unless P1111 is required for the State inspection, fuelling adaptations will normally be all that is
required for the vehicle to adapt itself and complete
