Scan Tool Diagnostics

A scan tool can read serial data from terminal 13 of the data link connector (DLC). The scan tool is used to read DTCs, and to clear some DTCs after a repair is completed. By design, certain DTCs can not be cleared. Certain DTCs can not be cleared for the ignition cycle once the DTC has been detected by the SDM.

To use the scan tool, turn the ignition OFF, connect the scan tool to the DLC, and turn the ignition switch to ON.

Follow the instructions in the scan tool manual. The SDM sends serial data from terminal 9 of the SDM to terminal 13 of the DLC.
