I have a 1994 Volvo 850 Wagon Non-Turbo. I check my A codes fairly regularly but I have never checked my B codes. My questions are, can you check B codes, and if you can, how do you check B codes? As you can see in the attachment, the A side has a light and a button, but the B side has neither. I've tried putting the jumper in the B side and pressing the button on the A side, but the light never lights. Anybody able to check for B codes? If you do, how do you do it?
Thanks
