Chevrolet 2007 Corvette Owner's Manual page 201

This light should come on briefly, as a check to
show you it is working, as you start the engine.
If the light does not come on, have it repaired.
This light will also come on during a malfunction
in one of two ways:
•
Light Flashing — A misfire condition has
been detected. A misfire increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis
and service may be required.
•
Light On Steady — An emission control
system malfunction has been detected on
your vehicle. Diagnosis and service may
be required.
If the Light Is Flashing
The following may prevent more serious damage
to your vehicle:
•
Reducing vehicle speed
•
Avoiding hard accelerations
•
Avoiding steep uphill grades
If the light stops flashing and remains on steady,
see "If the Light Is On Steady" following.
If the light continues to flash, when it is safe to
do so, stop the vehicle. Find a safe place to
park your vehicle. Turn the engine off, wait at
least 10 seconds and restart the engine. If the
light remains on steady, see "If the Light Is
On Steady" following. If the light is still flashing,
follow the previous steps, and see your dealer
for service as soon as possible.
