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.
