ABS and brake warning light is on

When I had that problem with the emergency light it was the sensor for emergency brake
The abs and brakes sounds like you are loosing pressure in the system

They only come on sometimes ?
Brake Warning Indicator
The instrument panel cluster (IPC) illuminates the brake warning indicator when the following occurs:
?€¢
The body control module (BCM) detects that the park brake is engaged. The IPC receives a class 2 message from the BCM requesting illumination.

?€¢
The EBCM detects a low brake fluid condition and sends a class 2 message to the IPC.

?€¢
The IPC performs the bulb check.

?€¢
An ABS-disabling malfunction also disables dynamic rear proportioning (DRP).

ABS Indicator
The IPC illuminates the ABS indicator when the following occurs:
?€¢
The electronic brake control module (EBCM) detects an ABS-disabling malfunction. The IPC receives a class 2 message from the EBCM requesting illumination.

?€¢
The IPC performs the bulb check.

?€¢
The IPC detects a loss of class 2 communications with the EBCM.

sounds like you have an intermittent problem for now ! a wiring issue or wheel speed sensor going bad. Need to check for codes in abs module , that will give you an Idea where to look first. These systems can set a lot of codes, component codes , wiring codes etc... need to know what code first.

Nope, but take it in. Brake problems are nothing to fool with They'll probabl tell you it's the ABS ECU. Not a cheap item.. However, it only affects the ABS system, not the brakes itself.

Hello, These warning lights are pretty accurate. Autozone, Advance, and Oreillys give free scans although the engine system and brake system can require different scanners.

Check your brake fluid level first. The ABS system requires sensors which require counting the revolutions of each wheel. Sometimes the sensors may break, but they can be blinded by dust and debris.

If you have a broken brake pad, the warning light can come on. Often the Emergency brake pad, inside the rear Rotor, can fall apart and trigger an ABS warning.

You need to inspect both the front and rear brakes or take your car to a brake shop for evaluation. Sometimes you can get a free estimate, and some shops can charge for inspecting the Emergency brakes because of the work needed to reach them.

The tcs/abs and brake lights are all on the same warning circuit. First i would check the brake fluid level and make sure it is topped off, next i would have the problem codes read and see if it helps you pinpoint the issue. If the light sometimes come on and sometimes are off i would suspect connection problems in the wiring. hope this helps

Do you mean the van is actually braking like a Starsky and Hutch move or that the warning lights indicate that they are on? If its lights then you may be low on brake fluid. Maybe a module leak

your abs unit is failing and needs replaced ...the procedure for testing is to backprobe green wire in abs connector and watch voltage wave pattern on a scope ....it will show voltage does not go from 0 to 12 but only 4 to 12 volts that verifies problem is abs controller.

its normal, whenever one or more wheel dont get enough traction the abs will kick in.. light up.
