Jeep Liberty: Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel filler cap is loose, improperly installed, or damaged, a “gASCAP” message will display in the odometer or a “CHECK gASCAP” message will be displayed in the Electronic Vehicle Information Center (EVIC). Refer to “Electronic Vehicle Information Center (EVIC)” in “Understanding Your Instrument Panel” for further information.
Tighten the gas cap until a clicking sound is heard.
This is an indication that the gas cap is properly tightened.
Press 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 light off.
