If none of the above have made the light turn off, your dealer/retailer can check the vehicle. The dealer/retailer has the proper test equipment and diagnostic tools to fix any mechanical or electrical problems that might have developed. Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or might begin programs to inspect the emission control equipment on the vehicle. Failure to pass this inspection could prevent getting a vehicle registration. Here are some things to know to help the vehicle pass an inspection: for five seconds. The instrument panel, including the check engine light, will light up and the ignition will be on, but the engine will not start - press the bottom of the Acc. button only briefly, less than five seconds, the accessory power mode will be turned on, but not the ignition. After the bulb check, press and release the Acc. button again to turn the ignition off and avoid draining the vehicle's battery. • The vehicle will not pass this inspection if the OBD II (on-board diagnostic) system determines that critical emission control systems have not been completely diagnosed by the system. The vehicle would be considered not ready for inspection. This can happen if the battery has recently been replaced or if the battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This can take several days of routine driving. If this has been done and the vehicle still does not pass the inspection for lack of OBD II system readiness, your dealer/retailer can prepare the vehicle for inspection. • The vehicle will not pass this inspection if the check engine light is on with the engine running. To perform a check engine light bulb check with the keyless ignition, make sure the transmitter fob is in the passenger compartment. See Ignition Positions on page 2-23. Press the bottom of the Acc. button on the instrument panel and hold the button down 3-46
