Scan Tool Data List

Scan Tool Data List
The scan tool provides these capabilities:
^ Displays the data list.
^ Displays current and history diagnostic trouble codes (DTC).
^ Clear the DTC after a repair is completed.

Important: Make sure the scan tool that you are using is functioning properly and has the latest software. Use of a malfunctioning scan tool or one that has old software can result in misdiagnosis and unnecessary parts replacement.

To use the scan tool, connect it to the data link connector (DLC) and turn the ignition switch to the RUN position.

The Transfer Case Scan Tool Data List contains all the automatic transfer case (ATC) related parameters that are available on the scan tool. The scan tool data list is arranged in alphanumeric order.

Use the Transfer Case Scan Tool Data List only after determining that:
^ The Diagnostic System Check - Vehicle has been completed.
^ There are no diagnostic trouble codes (DTCs) set.
^ Transfer case diagnostic tables indicate the system is functioning properly.

Scan tool values from a properly operating system may be used for comparison with the transfer case system you are diagnosing. The Transfer Case Scan Tool Data List represents values recorded under these conditions:
^ Engine is at idle
^ Closed throttle
^ Gear is in Park or Neutral
^ Accessories are OFF





Only the parameters listed are referenced for use in diagnosis. If all values are within the typical range described, refer to Testing for Intermittent Conditions and Poor Connections for further diagnosis. Diagnostic Aids
