Hey how are you,I will try to help you with this issue

if it done it before once , check the battery for 12 volts and holding , check battery cable for loose or corrosion, if looks good,lets try resetting it first in case was a glitch and we go from there

did you check the dlc connector fuse ?

what scanner you have

Master reset Procedure

1- Disconnect Battery Cables ( Negative & Positive Cables )you can use any electrical wire as an extension if battery cables don't reach .the reason we do that is to take any residual power in the wiring harness to try to reset the modules ,and there will be no spark created touching them since we took battery power source out of the loop by taking both cables off

2- Hold cables Together for 60 secs ,then let go

3- Wait 30 minutes

4- Make sure all doors are closed

5- Reconnect battery Cables ,Positive cable First

6- Lock & unlock the vehicles using the key from driver door side (if you have a key fob with no blade key, just lock & unlock using the key fob buttons)

7- Enter the vehicle and attempt to start

Please let me know

Thank You
