Customer: replied 1 year ago.
I still have not received your answer
Expert:  Chris (aka-Moose) replied 1 year ago.

Sorry I do not work the morning shift, which is why I have not responded yet.

Do you have access to a scan tool that can perform the key reprogramming to see if this resolves the lock light coming on?

Will that same scan tool access the BCM to see if its getting the input from the brake switch when you want to shift from park?

Customer: replied 1 year ago.
No I don't such a scan tool but I should be able to tomorrow
Expert:  Chris (aka-Moose) replied 1 year ago.

Super, let me know those results then.

i didnt really get a answer from you on my 2009 gmc canyon, what i found out on scan was the body control module was bad. the part # ***** i replace it with a interchange part #20987862,which didnt work at all not even ignition.i put back the old one and it does start the truck with original problem.
Expert:  Chris (aka-Moose) replied 1 year ago.

Thanks for coming back, any luck on seeing if the BCM is getting a brake signal input?

Customer: replied 1 year ago.
The brake light does work .what's happening the scan tool can't some modems like abs transfer case, when I start truck,everything inside stop working cluster ,fan ,radio,
Expert:  Chris (aka-Moose) replied 1 year ago.

Lets go after the easiest of these current issues the radio to see why it fails once started. Hopefully that diag and repair address most or all of the issues. Do you know how to remove the radio and do you have something to test 12 volt circuits?

Customer: replied 1 year ago.
I checked no voltage with truck running . the radio does work not running with ignition on.the fan also, the instrument cluster does light up with ignition but the gages don't move from zero.but as soon as you start motor everything goes goes off
Expert:  Chris (aka-Moose) replied 1 year ago.

So once started the radio fuse no longer has power?

Customer: replied 1 year ago.
That's correct ,the fan also
