How can the dashboard light be turned off?
After fixing the problems, the service technician may turn off the dashboard light. There are also situations under which the vehicle’s OBD II system can turn off the dashboard light automatically if the conditions that caused a problem are no longer present. If the OBD II system evaluates a component or system three consecutive times and no longer detects the initial problem, the dashboard light will turn off automatically. This could happen if the gas cap is not properly tightened after refueling. The OBD II system will detect the vapor leak and turn on the dashboard light. If the cap is properly tightened, the situation will correct itself and the light will turn off.
