Start/Stop Ignition Button Rapid Green Light

[newguy1776]

Disconnected the negative terminal today to install a subwoofer and now the truck makes no attempt to start and the start/stop button is flashing green when trying to start. Lights all come on, radio will come on if powered on, no accessory power on dash display just a parking brake warning. Tried disconnecting the battery again waiting 15/30 min, same symptoms. Hooked up a battery charger which showed the battery at 42%, attempted to start at 80% but once again doing the same thing... If the PATS was tripped due to a disconnected battery will I have to have it towed to the dealer or is there a work around? Tried resetting the BMS but without accessory power I can't see any indicator lights, and both key fobs lock, unlock and go through the process to autostart (horn) but does not start... I'm at a loss as I picked it up on Friday and can't even drive it now.

Did you try putting the key fob on the dead fob touch point in the center console. There is an outline of the fob to put the fob into in the center console.
Keep us updated on the resolution.

Hood open and closed, and I have tried the key out line as well as cycling lock and unlock via the key fob.

Having a locksmith come out to reprogram the key in an attempt to fix the possible PATS activation.

What’s throwing me off is that the key fob still locks and unlocks the vehicle but it will not start.

Check all the fuses you might have blown one installing amp wire

Didn’t even make it to installing the amp wire. I put the negative back on to run for some additional connectors because the kicker ones weren’t great and this all started. Will double check fuses just in case.

Check the hood switch to make sure it is working.
Also try to start the truck with the fob touching to the start button if you have not tried it already.
Next thing to try is to get a code scanner to see what is as stopping it from starting. Barrow one if you don't own one.

Diagnostic listed below with codes. Looks like the BCM is not communicating.

Try clearing all codes, see if that changes anything.
