2000 S-70 ABS module repair and install problem fix

[zeke1256]

I had a bad ABS module on a 2000 S-70. ABS, Brake light, Speedo and odometer not working, all at once and CEL on saying no communication P0600. Midwest ABS repaired it. I had a hard time getting the plug to seat firmly in, as the plastic clip on the black cover guard had broke when I opened it. ABS, Brake light, CEL, wouldn't go off. Spoke to Matt at Midwest, he said to remove the sliders which were inside the blue large plug, these "sliders" are rectangular thin plastic pieces on each side of the long side of the plug inside the plug housing. I removed the black plastic guard from the hinge and slid out the sliders, towards the hinge side of the plastic guard. These are kinda hard to see but were there, Not sure what these "sliders" do but it may have something to do with the locking cover device. The plug then fit down and in nice and firmly and hold it down several seconds to let any air move out, Matt advised this also. I then put the guard back on, started car and everything back to normal, CEL went off after several miles of driving, No more issues. Hope this helps anyone with this same problem.

Impressive. My son and I are having the same issues in an '86 BMW project. We've gone through nearly every part - wheel sensors, tone rings, wiring, relays..... We think it's time to risk a used ABS module. I haven't found any suppliers with rebuilt.
