WM idle relearn

[Fuctup]

I have a 2011 WM Caprice that in the process of replacing the throttle body after getting hit with limp mode as soon as i start it upon checking with my $20 obdII tool i got codes P1516-P2101 hence the throttle body replacement but after some research I found I need to do an idle relearn procedure after fitting new throttle body or will keep getting codes and limp mode I know how to do the relearn only thing i need is how do i reset the PCM Battery feed? Stage 2 of idle relearn.

There is no reset pcm feed.
The best you can do is a capacitor discharge. Disconnect negative terminal. Then switch on everything. Lights. Fan. Start the car. Brakes. Doors etc. then put it all back right. Then reconnect the battery. Best you can do.

To do more requires high end diagnostic tools
