Dodge Nitro: Onboard diagnostic system вЂ” OBD II
Your vehicle is equipped with a sophisticated Onboard Diagnostic system called OBD II. This system monitors the performance of the emissions, engine, and automatic transmission control systems. When these systems are operating properly, your vehicle will provide excellent performance and fuel economy, as well as engine emissions well within current government regulations. If any of these systems require service, the OBD II system will turn on the вЂњMalfunction Indicator Light (MIL).вЂќ It will also store diagnostic codes and other information to assist your service technician in making repairs. Although your vehicle will usually be drivable and not need towing, see your authorized dealer for service as soon as possible.
вЂў Prolonged driving with the MIL on could cause further damage to the emission control system. It could also affect fuel economy and drivability. The vehicle must be serviced before any emissions tests can be performed.
вЂў If the MIL is flashing while the engine is running, severe catalytic converter damage and power loss will soon occur. Immediate service is required.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel filler cap is loose, improperly installed, or damaged, a вЂњgASCAPвЂќ message will display in the odometer or a вЂњCHECK GASCAPвЂќ message will be displayed in the Electronic Vehicle Information Center (EVIC). Refer to вЂњElectronic Vehicle Information Center (EVIC)вЂќ in вЂњUnderstanding Your Instrument PanelвЂќ 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.
