codes HONDA CR-V 2006 RD4-RD7 / 2.G Owners Manual

If the indicator comes on
while driving, it means one
of the engine’s emissions control
systems may have a problem. Even
though you may f eel no dif f erence in
your vehicle’s perf ormance, it can
reduce your f uel economy and cause
increased emissions. Continued
operation may cause serious damage. If the indicator comes on repeatedly,
even though it may turn of f as you
continue driving, have the vehicle
checked by the dealer as soon as
possible.
This indicator may also come on
along with the ‘‘D’’ indicator.
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.If the battery in your vehicle has
been disconnected or gone dead,
these codes are erased. It takes at
least three days of driving under
various conditions to set the codes
again.
To check if they are set, turn the
ignition to the ON (II) position,
without starting the engine. The
malf unction indicator lamp will come
on f or 20 seconds. If it then goes of f ,
the readiness codes are set. If it
blinks five times, the readiness
codes are not set. If possible, do not
take your vehicle for a state
emissions test until the readiness
codes are set. Ref er to
for more
inf ormation (see page ).
If you have recently ref ueled your
vehicle, the indicator could come on
because of a loose or missing f uel f ill
cap. You will also see a ‘‘CHECK
FUEL CAP’’ message on the
odometer display. Tighten the cap
until it clicks at least once.
Tightening the cap will not turn the
indicator turn of f immediately; it
takes at least three days of normal
driving.

If you keep driving with the
malf unction indicator lamp on, you can
damage your vehicle’s emissions
controls and engine. Those repairs may
not be covered by your vehicle’s
warranties.

If you take your vehicle f or a state
emissions test shortly af ter 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 f or 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 f acility 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 f or retesting by
doing the f ollowing.Make sure the gas tank is nearly,
but not completely f ull (around
3/4). Make sure the vehicle has been
parked with the engine of f f or 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 f or 20 seconds.
Select a nearby lightly traveled
major highway where you can
maintain a speed of 50 to 60 mph
(80to97km/h)foratleast20
minutes. Drive on the highway in
D (A/T) or 5th (M/T). Do not usethecruisecontrol.Whentraffic
allows, drive f or 90 seconds
without moving the accelerator
pedal. (Vehicle speed may vary
slightly; this is okay.) If you cannot
do this f or a continuous 90
seconds because of traf f ic
conditions, drive f or at least 30
seconds, then repeat it two more
times (for a total of 90 seconds).
Then drive in city/suburban
traffic for at least 10 minutes.
When traf f ic conditions allow, let
the vehicle coast f or several
seconds without using the
accelerator pedal or the brake
pedal.
If the testing facility determines the
readiness codes are still not set, see
your dealer.
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
1/4of thescale(about3minutes).
