Acura 2007 TSX - Owner's Manual - Manual (Page 336)

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.
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
for more
information (see page ).
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. 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
).
