First there is no magic fix for this, generally you need a OBD 11 scanner to identify the fault. Auto Zone I am told do this service for free and tell you what the fault is.
There are however some things that you can check yourself first.
Check your brake fluid levels in the master cylinder.
Check your fuses to make sure that none are faulty.
Check that the wiring connectors to the ABS pressure pump system are properly connected and not corroded.
Check under the car at the four inside wheel hubs that the ABS wheel sensors are in securely in place and that the wires are properly attached and not damaged or lose. Most ABS faults are from the wheel sensors.
Check the wheel bearings to make sure that they do not have any play. This will result in the wheel sensor showing a fault.

Abs and hand brake light is on ... ?


It's not just hand break light , when the brake system master cylinder runs low on brake fluid , has a leak or the brake pads need to be replaced that light also comes on. And it will come on with the ABS light when a problem accrues. Problems can also happen when changing the battery with out hooking up an alternative power source > Battery Disconnect or Replacement Problems

Break lights


The problem is that you pressed the pedal to the max when you installed the new switch. The switch is improperly adjusted. You should just have to loosen the mounting bolts on the switch, have someone watch the lights and adjust the switch so that the lights come on when the pedal is depressed about a quarter inch. That should fix the problem because your ABS and ESP systems monitor the brake light switch and when it comes on so if it doesn't come on or stays on it messes up both of those systems.

Mercedes benz s420 series asr problem


Mostly this problem appends on winter time. I f you take your car to the dealership you could throw your money away like many people did and the problem still not solve. I fixed mine definitely by myself and you could do it too. 1- Open the hood, Jack the vehicle. On both front tires you will see a cable that looks like a Rca jack that connect to the brakes but it's bigger than RCA jack. 2- Follow that RCA cable to the hood and on the other end tou will see 2 small white wires that bring power to ASR and ABS system cut those 2 wires and you automatically disable the ASR and you solve the problem. As you know the ASR system is good for snow, it's like a 4 by 4 and you will need it later to drive safely in bad weather when there is snow. What to do next. After cutting the 2 small wires, I put 2 swiches in case I need the ASR in bad weather.One swich for ASR and the other one for ABS. when you cut one wire you connect both ends to the swich and you do the same for the second wire that you cut. The only one thing you will see is the ASR and ABS light will turn on on the dash. When driving in bad weather, open the hood and turn on the swich

Im install new brake swich because the abs light is on now the tile lights brakes not work


The fault is not with the brake swittch as the brake light works with the tail brake light whereas the ABS works from the failure of the ABS system.
So it is important that you recheck the connections once again to see there is a misconnection and check on the ABS unit.

1995 mercedes benz S 600, ASR came on and the vehicle won't climb up the driveway, no power , no code , what's the fix


I had a similair problem on my 600SEL 93, I read many articles and they were all bad news. When I checked the transmission fluid, I found out it was under a lot of pressure but the level was fine. After that the problem was gone.

The asr light is on and the car does not


the o2 senser would not cause the a.s.r. light to come on-there is only 2 things that the engine module and the a.s.r. module have in common. 1 is the e.a. actuater(throttle) and 2 is the base module. most likley either your acuater has to be resynchronized or the actuater itself is bad. have codes pulled from your h.f.m.,a.s.r.,e.a-i.s.c.-c.c modules and see what the codes say. You will probably find that they say e.a. actuater module is defective. the pig tail connecters go bad and they need to be replaced just be glad you do not have a 600 series because they cost about 1200 a piece and the v12 have 2 of them. If it is defective and you cannot resynchronize it there is a company that rebuilds them for about 1/3 the cost of a new one- good luck

ABS/Brake Light on GMC Envoy Dash


Might save you a whole lot of time if you stop by autozone, or Pep Boys, and get the free scan & see which sensor may be faulty, or sending code. I've had mine trip from driving in nasty weather for a while before, and a trip to the carwash, and concentrating the sensor areas with spray, (back of wheels area) put light back out, next start.
