Scan Tool Data List

The scan tool used provides the following capabilities:
^ Reads the data list.
^ Reads current and history Diagnostic Trouble Codes (DTCs).
^ Clears the DTCs after a repair is completed.

Before attempting to communicate with the SIR system, ensure that the scan tool contains the latest software. Connect the scan tool to the data link connector (DLC) and turn the ignition switch to the RUN position in order to use the scan tool.

The scan tool reads serial data sent from the Inflatable Restraint Sensing and Diagnostic Module (SDM) serial data output terminal 5 and terminal 17 to the DLC terminal 2. The following table shows the typical values of the data displays when the following conditions exist:
^ The ignition switch is in the RUN position.
^ The engine is OFF.
^ The driver seatbelt is buckled.
