  • What is Freeze Frame data?
  • What PIDs will this Scan Tool display for my vehicle?
  • Why do the Monitor icons continue to flash?

    The I/M MONITOR STATUS icons represent systems that are being tested by your vehicle for any possible faults. Monitors are special computer programs used by the vehicle’s computer to verify proper operation of specific emissions-related components or systems (Oxygen Sensor, Catalytic Converter, EGR Valve, Fuel System, etc.) to ensure their proper operation. If a Monitor icon is flashing; it indicates the associated system monitor is still being tested by the vehicles computer. A Monitor will not complete until the proper set of conditions are met for it to complete a drive cycle. When a Monitor icon is solid, it indicates the associated Monitor has completed its testing. A “Drive Cycle” is when the vehicle is driven through the necessary conditions during a single trip or multiple subsequent trips for the self-diagnosis to complete. You need to complete a full drive cycle for each of the monitors to complete its testing. Once the Drive Cycle finishes testing the system monitor you will receive a solid icon. In order to complete a “Drive Cycle” the vehicle must be able to start and run for the self-diagnosis to complete. Please refer to a vehicle service manual or owner’s manual for more information on the necessary conditions needed to perform the self-diagnosis and testing.
