Hi welcome to just answers my name is ***** ***** like you may have a bad ignition switch "Key On" alarm signal, or door open switch you can check this by accessing the Multi-Function Alarm module.
Backprobe pin C1 Light Green wire with a Digital Volt Ohm Meter (DVOM).
Should have near 12 V on this wire with the key in the key cylinder and the driver's door shut.
If so, replace the MFA module.
If voltage is not present on this wire, below 9 V, check the Tan wire for ground at the driver's door jamb switch. This wire should be grounded by the door jamb switch only with the driver's door open.
