P1765= transmission 12v supply relay control fault. Possible cause bad relay, open/shorted circuit, ecm defective. How to check & where? Would this also cause a p0743-torque converter solenoid circuit problem?

P1765 Could be the relay that transfers power to the TCC solenoid when activated-check the wiring back to the transmission control module
