I have a 1995 850 GLT it has an OBD II reader on the console - so I don't know if the 1996 reset procedures would apply?

My SRS light came on and has stayed on.

these are the codes read from the OBD I under the hood.

B-5 connector
1-1-2 internal fault sensor
2-2-3 passenger module - short to ground
2-1-3 steering wheel - short to ground
2-3-3 seat belt tensioner left short to ground
2-4-3 seat belt tensioner right short to ground

around the same time the light came i had to replace the heater core - as the one installed was leaking coolant -

my thought was that the coolant migrated into a connection for the service module underneath the console.

can I get an ebay - replacement? how close to the numbers have to be?
Is there someone to rebuild these units?

Thank you for your time to read and repsond.

Have you tried to clear the codes and see what comes back?

If you suspect that antifreeze corrupted the under seat module, a junk yard module is a possible solution - so long it has not been involved in a collision resulting in air bag deployment.
