2002 HONDA S2000 check engine

Your car 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 your car’s battery has been
disconnected or gone dead, these
codes are erased. It takes several
days of driving under various
conditions to set the codes again.If possible, do not take your vehicle
f or a state emissions test until the
readiness codes are set. To check if
they are set, turn the ignition ON (II),
but do not start 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 5 times, the readiness
codes are not set. Ref er to State
Emissions Testing f or more
inf ormation.(See page and .)
