NOTE:
*(1): The DTC in parentheses is the flash code the A/T gear position indicator indicates when the data link connector (DLC) is connected to the HDS, and in the SCS mode.
*(2): This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
