Hey how are you

you will need a factory scanner or equivalent to run a diagnostic scan & retrieve fault codes from the alarm module in the vehicle.
is it the module, the receiver, hood switch , door switch, wiring etc.. , it could be number of reasons & there is not a fuse or a relay that you can pull out to disconnect it uunfortunatly

Check the hood and door latches for being stuck open, open and close few times , locate the hood switch in the hood lock mechanism and lubricate with parts cleaner

You can try A master Reset but if there is a problem it want work, usually does if it is glicth or reseting the module

Master reset Procedure

1- Disconect Battery Cables ( Negative & Positive Cables )you can use any electrical wire as an extension if battery cables don't reach .

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

3- Wait 15 minutes

4- Make sure all doors are closed

5- Reconnect battery Cables

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 if that works for you

Thank You
