Kind of cryptic. Any idea where I should start troubleshooting? Something related to the driver's seatbelt latch?

 

Check wiring harness under the seat.

 

I had the same code, passenger side. I disconnected and reconnected the plug under the seat and the code went away, but it comes back intermittently

 

It is related to the seat belt, pull the plug as noted hit with it some contact cleaner. Pull the seat belt all the way out a few times it may help

 

It's recommended that you disconnect the battery and wait several minutes before disconnecting, reconnecting or otherwise touching the SRS wiring. Don't need to be accidentally setting of the seatbelt pretenioners and the airbags.

 

Adding a bit here to clarify. This is the seat belt latch (with the red button) pretensioner fault, it has nothing to do with the seat belt on the B pillar -- there are no electrical connections on a D2 to that seat belt roller. (many cars do though... ).

Like someone said above, I bet it's a dodgy connection or wiring issue and not the component itself.

 

I drove mine for a year with the SRS light on. checked all the plugs wires etc. Finally I was doing some work under the dash and saw the PO removed the srs fuse. I was kinda afraid to mess with it thinking there was a reason they took the fuse out. Finally nutted up and put a fuse in it. Fixed it! felt pretty dumb.
