On board diagnostics (OBD-II)

Your vehicle is equipped with a computer that monitors the engine’s

emission control system. This system is commonly known as the On

Board Diagnostics System (OBD-II). The OBD-II system protects the

environment by ensuring that your vehicle continues to meet

government emission standards. The OBD-II system also assists your

authorized dealer in properly servicing your vehicle. When the

indicator illuminates, the OBD-II system has detected a malfunction.

Temporary malfunctions may cause the

indicator to illuminate.

Examples are:

1. The vehicle has run out of fuel—the engine may misfire or run poorly.

2. Poor fuel quality or water in the fuel—the engine may misfire or run

poorly.

3. The fuel cap may not have been securely tightened. See Fuel filler

cap in this chapter.

4. Driving through deep water – the electrical system may be wet.

These temporary malfunctions can be corrected by filling the fuel tank

with good quality fuel, properly tightening the fuel cap or letting the

electrical system dry out. After three driving cycles without these or any

other temporary malfunctions present, the

indicator should stay off

the next time the engine is started. A driving cycle consists of a cold

engine startup followed by mixed city/highway driving. No additional

vehicle service is required.

If the

indicator remains on, have your vehicle serviced at the first

available opportunity. Although some malfunctions detected by the

OBD-II may not have symptoms that are apparent, continued driving

with the

indicator on can result in increased emissions, lower fuel

economy, reduced engine and transmission smoothness, and lead to more

costly repairs.

Readiness for Inspection/Maintenance (I/M) testing

Some state/provincial and local governments may have

Inspection/Maintenance (I/M) programs to inspect the emission control

equipment on your vehicle. Failure to pass this inspection could prevent

you from getting a vehicle registration. Your vehicle may not pass the I/M

test if the

indicator is on or not working properly (bulb is burned

out), or if the OBD-II system has determined that some of the emission

control systems have not been properly checked. In this case, the vehicle

is considered not ready for I/M testing.
