DTC problems 850 1995

i was trying to read the SRS fault ( to clear the light) but the B2 socket does not light or give anything not even 1-1-1, the wires underneath it seem ok , but how cani check for line continuety ( i have a multimeter)

2nd , replys about clearing codes seem confusing , to clear the codes at a certain socket u read its codes , then use what( 5s-5s, or 5-1-4-1 ) or should i read all the codes from all the sockets then clear them from only one socket?

thank you for ur help

DTC problems 850 1995

Is there any other thing not working in the car? I had same situation a couple of months ago. SRS light came on, radio and all heater fan went dead. And no response from the code box. After replacing the bad relay everything went back to normal including the code box. You may try checking for the fuses first, and then make a continuity check. If you need the procedure, I think I'll have it at home. I may try to locate it and send it when I get home.
good luck

the SRS came on when i was fixing the horne, normal.

and the DTC not lighting was my fault coz the SRS is in soket B5 not B2, B2 is for the cruise which i dont have :).
