2001 impala abs brakes light comes on only when you go thru water

the ABS system is defective, probably one or more of the sensors.

Traction control system works with the ABS sensors to monitor to monitor traction slippage.

First of all, make sure that your brake fluid level is correct. The brake, traction, and ABS systems on these cars all work together and if one thing goes wrong in any one part of the system, all of those lights will come on at the same time. Check your brake fluid level and be sure to use the correct DOT 3 brake fluid. DO NOT SUBSTITUTE with any other fluid. Let me know if your brake fluid level is ok and we'll go from there.

sometimes something like this can be bad tires or bad brakes. first inspect your tires and brakes. it also depends on how fast you are going it could be normal actually. now my fathers s10 did the same thing but his brakes started clicking and slower to stop, but his abs computer was bad.

brake fluid light goes on when the fluid is low. The traction control light may go on as well if the module detects a fault in the traction control system. The abs light may go on at the same time as the trac light if the wheel speed sensor is not sending a believable signal to the abs/trac module.

If one of the wheel speed sensors is faulty, or a hub is bad, that can cause the problem described.

Good luck on repairing this problem.

where do you hear moaning sound coming from ? Under the hood in engine bay ? That could be the ABS pump motor ! maybe going bad . service traction control light on ? DTC'S - diagnostic trouble code or codes stored . Have codes checked .

abs sensor is built into hub[bearing]common problem when changing them and or brakes r that the sensor connection is not properly reconnected or wire got damaged recheck the sensor wiring and that connector is connected to clip by strut clip is part of system

have the calipers and brake system checked, as for traction control is ran by abs system

your traction control mechanism uses the abs breaks to slow the spinning and give you better traction. i'm thinking your traction control sensor has gone bad

THE SPEED SENSOR IS LOCATED INSIDE THE HUB ASSEMBLY. THE TWISTED WIRES GOING TO THE SENSORS ARE PROBABLY AT FAULT. THE WHEEL SPEED SENSOR HARNESSES ARE AVAILABLE THROUGH A DEALERSHIP.

In the hub-bearing assembly (the part that the tire bolts on to and allows with tire to spin) there are sensors, they can and do fail. Also the wiring and connections can fail also. The only consequences of this problem being not fixed is that the ABS will not work (the breaks won't "pulse" when you start to skid) but you will still have breaks they will just work like regular conventional breaks that can lock the wheels, like in the cars of yore. Traction control will not work either, neither are serious but annoying. And the obvious the "service traction system" message will come up in the info box, the "traction off" light will be on and the "abs" light will be on. My dad's 02 impala has the same problem. A gm computer scanner can diagnose where the culprit lies. Good luck -Mike
