Check the exhaust system insulators for wear or loss as it may be metal on the support brackets.

hi for info the brakes warning light on dash is also an indication that brake fluid level is low? or there may be a leak resulting in fluid level drop ? also considering age of car you may need to inspect brake pads wear ? if your car has low brake pads wear indicators attached to pads ? or the hand brake switch req's checking to ensure it is being pushed to off position when h/brak is down ? so fluid level low is the obviouse 1st check as fluid will displace from reservoir as pads wear low hence the level indicator on fill cap trips on may i suggest if it is low level b4 you top up? check your b/pads if you have not done so recently? or replaced since new ? hope this helps you locate problem best wishes from the uk

it has to do with your air ride suspension best bet is take it to the dealer there is probably a problem with a level sensor. hope this helps you

Did you try to replace the starter cable? is the Truck turning over or just clicking.? If it's turning over and not starting. Best guess would be one of two things. Knock sensors Located under intake manifold. they get wet and deteriorate or the fuel pump. I've replaced all three on mine. 233k still running strong...
