NOTE: The "x" at the end of each DTC denotes a numeric character (0 thru 9) or an alpha character (A thru F) that you will see on the HDS display. The character is unrelated to your troubleshooting; it designates the SH-AWD control unit manufacturer and other details used for product analysis.
(1) DTCs are indicated by the SH-AWD indicator when the data link connector (DLC) is connected to the HDS.
