Airbag SRS on with 13 DTC codes. Help!

[Arv]

I shorted the E1 and Tc diagnostic terminals and got the 13 codes below. Cruise control and horn are working fine. Aside from the power door lock issue, no electrical issues that I know of. This is on a 2000 Sports Ed 4WD.

DTC codes:13,14,31,43,44,47,48, 53, 54, 63, 64, 73, 74

Where do I start troubleshooting, I’m hoping one issue is triggering all these codes as it is hard to believe that all of SRS components suddenly and all at the same time had issues.

Have the Torque Pro but would be willing to purchase another app that supports the SRS/ABS systems like Fusion??? (What do you recommend that works well on Android an BT ELM adapter) If its going to help me troubleshoot the issue.

Seems like wire harness or spiral cable (even though horn and cruise are working)??? Looking at these codes in the FSM it could be anything from the wiring to the sensors and squibs. Is there a table with all these codes somewhere buried in the FSM?

Thanks!

I have a copy of the service manual with the DTC charts. the SRS codes don't list every one you did, but did get a good amount of them.

Let me know if there's other DTC codes besides SRS and I can send those charts too. Attached a PDF and images of the chart

Start by checking all the fuses, the 30 amp fuse controls the door lock function.
