Ever since an IP replacement in November, I have been experiencing an ABS warning light if I accellerate too fast from a stop. Goes off after several seconds. Not until I drove the MH at night, which I rarely do, did I also notice low brake fluid warning light also comes on with the ABS light. That light is partially hidden by my 18 inch steering wheel and generally poor visibility due to the low profile dash board built by NRV!

I added DOT3 brake fluid ( quite a bit. About a pint. ). This has stopped both warning lights from coming on during a rapid accelleration. The coach is in the shop now for a previously diagnosed ABS computer replacement. Not so sure now if the problem isn't related to the IP which coincided with low fluid level and colder weather??
Anybody know for sure if low fluid level warning is supposed to also set off ABS warning?

I would believe that the ABS an your low fluid lite are all part of the same system. My question would be why are you looseing fluid in your braking sys. with a fairly new coach? Is the shop looking into this?---"007"

Yup, Shop asks same question. I haven't seen any indications of brake fluid leakage on the lines or the wheels. Only thought I have is that 23k miles towing a 3500-4000 # toad has worn pads down enough to lower resevoir level to that critical sensor level. I know level was OK 2 years ago when I bought it. This is the one that had lumpy fluid too. I do use tranny as often as I can for braking assist and I have an M&G Engineering brake system that seems to work great????

Shop is giving it another look before they replace the ABS computer.

There is a recall about reprogramming the IP logic because of the low fluid light. Check with WCC Customer Service first.

Models effected are 2003 models.

WH servicer found no leaks and no error codes. So warning lights were probably activated by low BF level. Since adding fluid, no more warning lights....so far. Since no malfunctions were found, they did not replace the ABS computer.
Still seems curious that low BF would trigger ABS. Why not just have a single warning light for both.
Or perhaps the IP reflash will fix that..

Low brake fluid will definately trigger ABS warning light. Has same problem, dealer finally found small leak at fitting where chasis was extended. only dripped when brakes were applied, and did not leave any tell tell signs on frame or under coach. Dealer replaced iron fitting with brass one, that fixed problem, no more fluid loss or ABS lights.
