Malfunction Indicator Lamp - Acura 2008 TSX Owner's Manual

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 your vehicle has an automatic
transmission, the malfunction
indicator lamp may also come on
with the ''D'' indicator.
You will also see a ''CHECK
EMISSION SYSTEM'' message on
the multi-information display (see
page 84 ).
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 may be erased. It takes
several days of driving under various
conditions to set the codes again.

Malfunction Indicator Lamp

To check if they are set, turn the
ignition switch 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 Emissions
Testing for more information (see
page 362 ).
