94 Areostar Rear ABS warning light - Ford Forums

04-03-2005, 14:01

My problems started when the rear wheel Cyl leaked and allowed the fluid
level to drop and allowed air into the system.

Rear Cyls, and new shoes now have been replaced and all four wheels have
been bled, and the fluid level is full.

I'm looking for a solution for two problems. First problem is the Red brake
failure light will not go out after all the wheels have been bled, and the
second is the REAR ABS warning light stays on.

I can make the Red Brake warning light go out by disconnecting the
Proportioning value switch from the wiring harness. The Question is how is
that switch reset back to be off in the normal operating mode, or is it
normal to be in the off mode when the no pressure is applied from the brake
pedal.

I don't have a clue as to why the READ ABS warning light is ON after the
engine is running. The sensor on the rear pinion is in place and hooked
up, and it was functional before the leak is the braking system. I'm
thinking that it may be in the ABS sol value that is after the Proportional
value.

Anyone have a clue, and have model experience?

you need to reset the brake equalization valve to get the brake failure
light to go out. as for the abs light, there could be two things causing
this. first, the abs sensor may be bad. secondly, this car may have an abs
system that has a fluid pump, and it may be low on fluid. not sure though,
never worked on one of these cars

open a front caliper and bleed it
= out the pressure
check that both brakelights work

Problem solved, Replaced the RABS sol value, and the prop value, very
expensive, but it worked. blead the brake in order of right rear, left
front, right front, left rear as discribed in repair manuel. thanks

Your e-mail is confusing to me.Would you be so kind to explain specifically
and spell out the complete" replaced RABS sol value and the prop value".I
think you might have mis-typed like I do very frequently.I believe you have
the solution for my similar problem.That's why I need specific names for the
parts I will need to buy.I sincerely will appreciate your help.THANKS!

I replaced the value that has the warning switch on it. It's call a
"Pressure Differential Value and Warning lamp switch". Then I replaced the
RABS value or know as a "Dual Solenoid Eletro-Hydraulic Value". This was
a shotgun fix, since the wife wanted the car fixed ASAP, and there was
dirt, rust, and leaks in the rear system when I started. Now I have flushed
the system with new fuild, and have new parts, I feel that she is now
driving a car with safe brakes. One last thing, to make sure that there was
no air in the system, I bled the brakes a second time to make sure that the
fuild ran clear and no air bubbles. This system that's on this van dosn't
have a pump built into the ABS controls. the only pressure that is applied
is from the brake pedal. I tested the new part before installing it, and I
could apply small amount air pressure to the inlet port, and feel that
there was a sign that it was reaching the output port with out being
energized. With this thought, I felt that just bleading the brake will
remove the air from the value.
