Transmission Scan Data Values

The data stream scan values, listed below, are typical for the test parameters of a Tech-1 scanner or equivalent scan tool connected to the Data Link Connector (DLC) (formerly the ALDL) diagnostic connector, and under the following conditions:

Engine running at idle/closed throttle
Lower Radiator Hose Hot
Park or Neutral
System operating in "closed-loop."
Accessories "OFF."

Many of the parameters show "data" rather than voltage or resistance values, and cannot be read using a volt/ohm meter.
