HONDA 2014 Insight - Owner's Manual - Manual (Page 393)

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. 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).
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 (4° and 35°C).
Keep the vehicle in Park. Increase
the engine speed to 2,000 rpm, and
hold it there for about 3 minutes.
Without touching the accelerator
pedal, let the engine idle for
20 seconds.
