ABS Codes

[johnwartjr]

I had both front hubs replaced about a week ago, as the left side wheel bearings were getting uber noisy and it just made sense to replace them both.

Before the hub replacement, I had the following code:

B1194 ABS $28 Antilock Brake System Outlet Valve Coil Left Front Circuit Malfunction

I cleared it at Advance, and it went away for awhile. 2-3 days, and it came back.

After replacing both hubs, I now get the same code, plus the one referencing the right side.

B1194 ABS $28 Antilock Brake System Outlet Valve Coil Left Front Circuit Malfunction

B1210 ABS $28 Antilock Brake System Outlet Valve Coil Right Front Circuit Malfunction

I clear them, the code reader says they are cleared, and they return immediately upon turning the key to accessory - I don't even have to crank the engine!

I checked both ABS relays in the box behind the battery upon the advice of the guy at the parts store - and they are both fine.

Where should I look next? It's the last trouble code on the wife's explorer, and I'd love to be codeless

I think there is a sensor on each wheel and another one somewhere else if I remember correct. Don't count on me remembering things though. I even forgot where I put my Memory pills.

those are hcu/ecu codes not sensor codes.

I'm not familiar with these, do I just need to disconnect the battery to clear them?

more like the actuators in the hcu or ecu, cant be commanded.

Oh, OK, so the HCU is potentially bad then.. that's the thing in the engine compartment between the master cylinder and the battery.. I think I follow now

 

[waskly]

the hcu solenoids inside it are bad, or the ecu can't control them. its the assembly that the two brake lines run into and 4 come out.

i cant think of the location on a 96 most are under the drivers side of the truck me thinks, earlier models i think had it under the hood.

well since i cant remember it, i found a thread that shows what it looks like.
