NOTE: If the vehicle does not report a result
and the conditions where correct. It may take
up to two weeks to fail the small leak monitor.
DO NOT use this test to attempt to determine
a fault. Use the
information procedure for finding a small
leak. If there are no faults and the conditions
are correct this test will run and report a
pass. Note the Small leak test can find leaks
less than 10 thousands of an inch. If a small
leak is present it takes approximately one
week of normal driving to report a failure.
