Scan Data
NOTE:
Information contained in these tables is typical of readings taken on vehicle with engine idling, upper radiator hose hot, throttle closed, transmission in Park or Neutral, closed loop status achieved and all accessories off (except as noted in tables). Data parameters are updated every 1 1/4 seconds. Not all devices and systems are used on all models. For additional information, see tester owner's manual.
