B1877 = Driver-side pre-tensioner front buckle circuit resistance high.
B1885 = Driver-side pre-tensioner front buckle circuit resistance low.

I'd say the seat belt buckle assembly needs to be replaced.
High resistance could be an open circuit. Low resistance could be a short circuit.
Either way, the system isn't working properly, and should be repaired.
