If you take your vehicle for an

emissions test shortly after the

battery has been disconnected or

gone dead, it may not pass 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.

Without touching the accelerator

pedal, start the engine, and let it

idle for 20 seconds.

Make sure the vehicle has been

parked with the engine off for 6

hours or more.

Make sure the ambient

temperature is between 40° and

95°F.

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 retested within the

next two or three days, you can

condition the vehicle for retesting by

doing the following.

Make sure the gas tank is nearly,

but not completely, full (around

3/4).

Keep the vehicle in Park

(automatic transmission) or

neutral (manual transmission).

Increase the engine speed to 2,000

rpm,andholditthereuntilthe

temperature gauge rises to at least

1/4ofthescale(about3minutes).

Without touching the accelerator

pedal and let the engine idle for 20

seconds.
