HONDA 2005 Insight - Owner's Manual - Manual (Page 182)

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 your 12 volt vehicle’s battery 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 ON (II), 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.
