    Does the circuit that indicated ON have continuity to ground?

    YES 

    Repair a short to ground in the wire between the corresponding transmission range switch connector terminal, the A/T gear position indicator, and the PCM.

    NO 

    The wires are OK. Update the PCM if it does not have the latest software , or substitute a known-good PCM , then recheck. If DTC P0705 goes away and the PCM was updated, troubleshooting is complete. If DTC P0705 goes away and the PCM was substituted, replace the original PCM .
