Scan Tool Data List

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

Make sure the scan tool contains updated software before attempting to communicate with the SIR system. To use the scan tool, connect it to the Data Link Connector (DLC) and turn the ignition switch to the RUN position. The scan tool reads serial data sent from the Inflatable Restraint Sensing and Diagnostic Module (SDM) serial data output terminal 5 and 17 to the DLC terminal 2. The following table shows the typical values of the data displays under the following conditions:
^ Ignition switch in RUN
