State Emissions Testing

Testing of Readiness Codes

If you take your vehicle for a state
emissions test shortly after the

battery has been disconnected or
gone dead, it may not complete the
test. This is because of certain
"readiness codes" that must be set in
the on-board diagnostics for the
emissions systems. These codes are
erased when the battery is
disconnected, and set again only
after several days of driving under a

variety of conditions.

If the testing facility determines that
the readiness codes are not set, you

will be requested to return at a later

date to complete the test. If you must

get the vehicle re-tested within the
next two or three days, you can
condition the vehicle for re-testing
by doing the following.

Make sure the gas tank is nearly,
but not completely, full (around
3/4).

Make sure the vehicle has been
parked with the engine off for 8
hours or more.

Make sure the ambient
temperature is between 20° and
95° F.

Without touching the accelerator

pedal, start the engine and let it
idle for 20 seconds.

Keep the vehicle in Park

(automatic transmission). Increase

the engine speed to 2,000 rpm and
hold it there until the temperature
gauge rises to at least 1/4 of the
scale (approximately 3 minutes).
