ONBOARD DIAGNOSTIC SYSTEM (OBD II)
CARB emission control vehicles are equipped with a
sophisticated onboard diagnostic system called OBDII.
This system monitors the performance of the emissions,
engine, and automatic transmission control systems.
When these systems are operating properly, your vehicle
will provide excellent performance and fuel economy, as
well as engine emissions well within current government
regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light.” It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be driveable and not
need towing, see your dealer for service as soon as
possible.
CAUTION!
Prolonged driving with the “Malfunction Indicator
Light” on could cause further damage to the emis-
sion control system. It could also affect fuel economy
and driveability. The vehicle must be serviced before
any emissions tests can be performed.
If the “Malfunction Indicator Light” is flashing,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
