Typical Scan Data Values
The Typical Scan Data Values are an average of display values recorded from normally operating vehicles. The Typical Scan Data Values are intended to represent what a normally functioning system would display. The values you get may vary due to a low battery charge or other reasons. But they should be very close. Use the Typical Scan Data Values only after the On-Board Diagnostic system check and finding the on-board diagnostics function properly with no diagnostic codes displayed. Engine must be at operating temperature, idling in Closed loop, Closed throttle, Park or Neutral, and accessories OFF.
