    It looks like you also need pages 05-1159 and more of the repair manual to follow the steps.

    I have a question when you saying the detection condition Transmission control ECU IG OFF command malfunction, - do that mean the transmission control ecu is not getting any power or signal?

    I saw alot of people jumping the fuse box when they got the parking P malfunction error on their mfd but they never say what code they got.

    That's just the very brief memory jogger the manual says in the DTC chart. What you need to do to actually diagnose the code is in the HV section of the repair manual.

    Yeah I'm totally confused by all that no doubt . Not sure what ground slips off at engine for HV battery replacement? I've never been to the front of the car had the hood up for a battery replacement hv that is .

    do you know if the jumping the fuse with a wire works? I see alot of people on youtube using that trick. people say some times the fuse to another fuse wire it get corroded or the wire get loose and throw a p malfunction on the MFD.
