OOSE UEL ILLER AP
After fuel has been added, the vehicle diagnostic system
can determine if the fuel filler cap is possibly loose,
improperly installed, or damaged. If the system detects a
malfunction, the "gASCAP" message will display in the
odometer display. Tighten the gas cap until a "clicking"
sound is heard. This is an indication that the gas cap is
properly tightened. Push the odometer reset button to turn
the message off. If the problem persists, the message will
appear the next time the vehicle is started. This might
indicate a damaged cap. If the problem is detected twice
in a row, the system will turn on the MIL. Resolving the
problem will turn the MIL off.
