hey i had the same problem with the 2 lights being on, check the brake fluid, its probly low, mine said low when the lights are on, then if you have the engine on, shut it off and start it back up and the lights should turn off

That's news to me. As far as I know the Dodge RWAL system does not
have a brake fluid level sensor. It uses just a compartmentalized front/rear
standard master cylinder used for many years with a dual braking system.
 
The ABS controller senses only two inputs. Pulses from the the VSS sensor
in the diff and a brake pressure switch located on the proportioning valve
provide input to the ABS controller (CAB)
 
If the rear wheels lock up, the differential is no longer turning and their
will be no pulses coming into the CAB, so it starts to initiate ABS
braking on the rear wheels for a RWAL system.
 
If the VSS is no longer functioning and the ignition is still on,
 it may think that that is a wheel lockup if the vehicle is moving and continue with ABS. The speedometer not working or erratic would be another indication of a VSS problem.
 
If there is a fluid loss in the front or rear brake system, the differential
fluid pressure switch will activate and it will turn on the ABS and Brake
indicator.
 
Lifting the battery and resetting the controller only works if there are
no faults present. If the brake pressure switch is still operated one
way or another, signifying an open brake line somewhere, the
ABS and Brake light will stay on until the braking system is repaired and
bled.

I checked the level and it is full! Don't want to overfill it.

The level of brake fluid in master cylinder has nothing to do with your
ABS/Brake indicators being on. As long as the fluid doesn't drop down
inside the reservoir to the point that the master cylinder is sucking in air, the possible
reasons for the ABS/BRAKE light coming on..could be:
 
1. You have a pressure leak somewhere in one of the lines, or calipers
or wheel cylinders
 
2. Proportioning valve is stuck in one position?
 
3. VSS sensor not providing adequate pulses to the CAB. If this was the
case, the speedometer gets affected as well, since the same sensor
is used to calculate Vehicle speed by the PCM.
 
4. HCU (ABS pump) fault in either the isolation or dump solenoid valves.
 
5. ABS controller itself..although this is much lower probability.

I haven't done anything yet to correct the problem of the ABS and brake light coming on. Yet with the warmer than normal weather we have had this winter it has helped me discover that when it is colder (around freezing temps) the lights come on more. Although when we had days when it was say around 50 degrees, I noticed that they did not light. I'm thinking it has something to do with the brake fluid viscosity? Not sure. I am thinking of replacing the brake fluid to see if it helps the situation. What do you think?

If only one brake is locking up, it could be a bad brake hose on that side. That's more common with a single front brake locking, but have the rear lines checked.

#181 of 181 Antilock controller repair by cheeze74

Mar 13, 2013 (6:51 am)

I posted a message last year about my ABS and brake light coming on intermittantly. Now it stays on all the time. I suspect the CAB or controller to be the problem. I thought I saw a post once about a company that repairs them. Does anyone know who that company is so I can check into it? Thanks!
