Scan Tool Data List

The scan tool used provides the following capabilities:
^ Read the data list.
^ Read current and history diagnostic trouble codes (DTCs).
^ Clear 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. The scan tool reads the serial data sent from the Inflatable Restraint Sensing and Diagnostic Module (SDM) serial data output terminal 5 to the DLC terminal 9. The following table shows the typical values of the data displays under the following conditions:
^ The ignition switch is in the RUN position.
^ The engine is OFF.
^ The driver seatbelt is buckled.
