I have a 2000 Range Rover. The ABS, TC & Brake lights are on. Off when I start the vehicle but come on right away after I start to move. I recently had a problem with the brakes (no power assist) and decided to change the fluid before anything else. I used the proper bleeding procedure and believe it was done correctly. The problem remained so I replaced the accumulator. The brakes are working now but the three lights remain. I did not bleed the brakes after changing the accumulator so I plan on doing that this weekend but I am trying to confirm that air in the system or low system pressure will trigger these lights.

Did you get anywhere on this? I have something similar I suddenly started getting the lights and Faultmate is showing it as a pressure switch failure.

I had a similar problem, it was the brake switch actuator. Easiest way to tell is check to see if your brake lights have stopped working, very easy fix to replace.

I have had two cases with the same pressure switch fault reported by rovacom and both times the only fix was to change the pressure switch on the pump. I was fortunate enough to get serviceable used switches from the breaker. Try LR but I think I got their last two.

I have not had time to bleed the brakes yet but will do it tomorrow. Initially I did suspect a problem with the pressure switch but after replacing the accumulator the brakes started working and the pressures switch is shutting the ABS pump off within a few seconds like it's suppose to. I realize that doesn't necessarily mean the switch is working properly. Based on that do you think the pressure switch is faulty causing the Brake, ABS and TC lights to come on?

There are two separate switches in the pressure switch.

The warning lights illuminate for a number of different reasons as the ABS system is made up of quite a few components. Your best bet will be to hook the car up to a diagnostic system and get a positive identification of the problem.
