Service Engine Soon
If it illuminates when the engine
is running, the on-board
diagnostics system notifies you
that the emission control system requires
service.
If it flashes, engine misfire may be
occurring. An increase in exhaust gas
temperatures can damage the catalytic
converter or other vehicle components.
Avoid heavy acceleration and deceleration
and have your vehicle immediately
serviced.
It illuminates when you switch the ignition
on prior to engine start to check the bulb
and to indicate whether your vehicle is
ready for Inspection and Maintenance
(I/M) testing.
Normally, it illuminates until the engine is
cranked and turns off if no malfunctions
are present. However, if after 15 seconds
it flashes eight times, this indicates that
your vehicle is not ready for inspection and
maintenance (I/M) testing.
See Catalytic Converter (page 116).

Flashes during a traction control
event.
If it does not illuminate when you switch
the ignition on, or remains on when the
