A service technician will
turn off the dashboard "check engine" light after most repairs. This
resets the vehicle's emission system components to "not ready". The
status remains "not ready" until the vehicle's computer has had adequate
time to review the repaired component. This happens after the vehicle
is driven for a period of time established by the manufacturer.
If the vehicle's emissions system status is "not ready" when it is presented at the E-Check station during the initial test cycle,
a tailpipe emissions test may be conducted. If the vehicle is
transferred to another test type, the vehicle must remain on the
different test track until the vehicle passes the emissions test or
receives a waiver. For example, if the vehicle undergoes an OBD II test
and fails, it cannot be downgraded to a tailpipe test on a re-test; the
vehicle must pass the OBD II test.
For initial and subsequent tests, if a dashboard light is on when the vehicle is presented at the E-Check station, the vehicle will fail the test.
How can the vehicle status be made ready?
When a vehicle is driven through its normal drive cycle, the computer reviews the emission control
system and if the vehicle was properly repaired, the system resets itself to ready. A normal drive
cycle includes operation at both cruising speeds and in stop-and-go traffic for up to a couple
weeks. This process should be followed before bringing the vehicle in to be tested.
