Malfunction Indicator Lamp - Honda CR-V 2006 Owner's Manual

Malfunction Indicator Lamp

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 feel no difference in
your vehicle's performance, it can
reduce your fuel economy and cause
increased emissions. Continued
operation may cause serious damage.
If you have recently refueled your
vehicle, the indicator could come on
because of a loose or missing fuel fill
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 off immediately; it
takes at least three days of normal
driving.

If the indicator comes on repeatedly,
even though it may turn off as you
continue driving, have the vehicle
checked by the dealer as soon as
possible.
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.
This indicator may also come on
along with the ''D'' indicator.
Readiness Codes
Your vehicle has certain ''readiness
codes'' that are part of the on-board
diagnostics for 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
malfunction indicator lamp will come
on for 20 seconds. If it then goes off,
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. Refer to State
Emissions Testing for more
information (see page 254 ).
