The Powertrain On-Board Diagnostic II (OBD II)
system consists of the hardware and software
necessary to monitor the operation of the
powertrain. The OBD II system is designed to
check the function of the vehicle's powertrain
control system during normal operation. If an
emission problem is detected, the Check Engine
Warning Light (in the cluster) is turned on.

[LG04575(ALL)05/95]
Modification or additions to the vehicle may
cause incorrect operation of the OBD II system.
Additions such as burglar alarms, cellular
phones, and CB radios must be carefully
installed. Do not install these devices by tapping
into or running wires close to powertrain control
system wires or components.
[LG04600(ALL)07/95]
The light comes on briefly when you turn the
ignition key to the ON position, 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.
[LG04650(ALL)08/95]
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.
[LG04700(ALL)08/95]
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.
