284 MAINTAINING YOUR VEHICLE

ONBOARD DIAGNOSTIC SYSTEM — OBD II

CAUTION! (Continued)

Your vehicle is equipped with a sophisticated Onboard

Diagnostic system called OBD II. This system monitors

the performance of the emissions, engine, and auto-

matic transmission control systems. When these sys-

tems are operating properly, your vehicle will provide

excellent performance and fuel economy, as well as

engine emissions well within current government regu-

lations.

The vehicle must be serviced before any emis-

sions tests can be performed.

• If the MIL is flashing while the engine is running,

severe catalytic converter damage and power loss

will soon occur. Immediate service is required.

Onboard Diagnostic System (OBD II)

Cybersecurity

If any of these systems require service, the OBD II

system will turn on the Malfunction Indicator Light

(MIL). It will also store diagnostic codes and other

information to assist your service technician in making

repairs. Although your vehicle will usually be drivable

and not need towing, see your authorized dealer for

service as soon as possible.

Your vehicle is required to have an Onboard Diagnostic

system (OBD II) and a connection port to allow access to

information related to the performance of your emis-

sions controls. Authorized service technicians may need

to access this information to assist with the diagnosis

and service of your vehicle and emissions system.

WARNING!

CAUTION!

• ONLY an authorized service technician should

connect equipment to the OBD II connection port

in order to diagnose or service your vehicle.

• Prolonged driving with the MIL on could cause

further damage to the emission control system. It

could also affect fuel economy and driveability.

WARNING! (Continued)

• If unauthorized equipment is connected to the

OBD II connection port, such as a driver-behavior

tracking device, it may:

In some localities, it may be a legal requirement to pass

an inspection of your vehicle’s emissions control sys-

tem. Failure to pass could prevent vehicle registration.

• Be possible that vehicle systems, including

safety related systems, could be impaired or a

loss of vehicle control could occur that may

result in an accident involving serious injury or

death.

• Access, or allow others to access, information

stored in your vehicle systems, including per-

sonal information.

For states that require an Inspection and Main-

tenance (I/M), this check verifies the “Malfunc-

tion Indicator Light (MIL)” is functioning and is

not on when the engine is running, and that the OBD II

system is ready for testing.

Normally, the OBD II system will be ready. The OBD II

system may not be ready if your vehicle was recently

serviced, or recently had a dead battery or a battery

replacement. If the OBD II system should be deter-

mined not ready for the I/M test, your vehicle may fail

the test.

For further information, refer to “Cybersecurity” in the

“Understanding Your Instrument Panel” section.

Your vehicle has a simple ignition actuated test, which

you can use prior to going to the test station. To check

if your vehicle’s OBD II system is ready, you must do

the following:

1. Cycle the ignition to the ON mode, but do not crank

or start the engine.
