Brake, B-LSD warning lights

I have recently been having these lights come on when I first start driving in the morning. Usually after pulling away from the second or third stop of the day, the BRAKE warning light comes on, followed shortly by the B-LSD light. Usually the BRAKE goes off after a few minutes, but the B-LSD stays on until the truck is turned off and started again.

Anyone else have this problem? Brakes seem to work fine. Low fluid? I looked at it but it seemed OK. Is there an error code that is stored that the dealer can retrieve?

It could be a few thing but I hade the "Brake" + "Slip" came on usually at hard take off. Fluid level seem fine but I top it off anyway and the lights went away.

Update: although the fluid level was between MIN and MAX, adding brake fluid to 'top-off' the reservoir fixed the problem.

If the fluid is low it will set a code "Low brake fluid level". The code should erase itself after you top off the fluid level. I've never seen the brake light or any other lights for that matter come on when the fluid level was between Min. and Max. It usually has to be a lot lower (about half way) before it sets codes and lights.
