P0705 is a Crossfire code that indicates there is a problem with the Can Bus between the SLA and the PTCM, or the TCU and the PTCM. You need to deal with this first. Check the Can bus at connector 4 at the PTCM Pin 1 (Can +) pin11 (Can-). Back probe the wires and you should get 60 ohms. If you disconnect the connector from the PTCM you should get 120 ohms on the PTCM and on the connector with the wires. READ THIS THREAD: HELP, RCM, SLA, TCU
If you skip this step you are digging a deeper hole.Do you have any DTC for the SLA?
