The light comes on briefly when you turn the ignition key to
ON, but it should turn off when the engine starts. If the light
does not come on when you turn the ignition to ON or if it
comes on and stays on when you are driving, have your vehicle
serviced as soon as possible. This indicates a possible problem
with one of the vehicle’s emission control systems. You do not
need to have your vehicle towed in.
[IS04400(ALL)05/96]
If the light turns on and off at one (1) second intervals while
you are driving the vehicle, it means that the engine is
misfiring. If this condition persists, damage could occur to the
engine or catalytic convertor. Have your vehicle serviced at the
first opportunity. You do not need to have your vehicle towed
in.
[IS04500(ALL)05/96]
If the light turns on and off on rare occasions while you are
driving, it means that a malfunction occurred and the condition
corrected itself.

[IS04600(ALL)08/96]
An example of a condition which corrects itself occurs when an
engine running out of fuel begins to misfire. In this case, the
Service Engine Soon Warning Light may turn on and will then
set a Diagnostic Trouble Code indicating that the engine was
misfiring while the last of the fuel was being consumed. After
refueling, the Service Engine Soon Warning Light will turn off
after the vehicle has completed three consecutive warm up
cycles without a misfire condition occurring. A warm up cycle
consists of engine start from a cold condition (engine at ambient
temperature) and running until the engine reaches normal
operating temperature.
[IS04700(ALL)08/96]
On the fourth engine start up, the Service Engine Soon Warning
Light will turn off as soon as the engine begins to crank. It is
not necessary to have the engine serviced.
