Traction control and ABS

[hpbongers]

I have the three lights on all the time. The odd time they turn off. Switch is ok. Wheel sensors replaced in the front and rear ok. Tried it when it was functional last week. I have the 97 type ABS so can't take it apart to look for bad connections. I tried the INPA software but doesn't show much. No other fault codes. Is my only option to replace the computer? I ended up replacing the tranny computer to fix the "trans fail safe".

This is a great troubleshooting guide for an E39, should be the exact same for us.

OK, replaced the ABS/DSC computer and no change. Now seems the only option is the pump/valve, but i have the 87 vertical version with a connection at the bottom that doesn't seem to disconnect. Anyone with info. All pictures seem to be of the back plate withe the horizontal connector. How do i dissemble it?
