help , how dose on test the abs sensors , i replaced everything but the sensors and i have no clue on how to test to see what else need to be replaced...


also both of my front calpers craped out at the same time ? were leeking bad. what would cause this ?

 

We need more info.
When you say you replaced everything what do you mean?
What is the problem with the ABS?

 

ok, i replaced my master cyl, booster, abs brain , back and front calipers, extended front and back brake lines.


what i want to learn how to do is test the abs sensors with out having to take my whole front and rear end apart. the dealer is telling me its a guessing game, but with the hi cost and many hours of labor to replace the wire/abs sensors .


and second ,my buddy is telling me to man up, and just unplug my abs brain?


why i started all this , front brakes both were leaking, when i would turn at slow speeds or higher the brakes would not work correctly, and make strange sounds..

i thank i know what i need is a black box(to test the ecu wire plug) and a completed wire system brake down of the entire abs system so i can test each cercit ( i am thinking its something silly like a ground or damaged wire plausibly?




car is at 130000 is about to roll over any time i get it driving

past history that i know :
got it at 89000 was last dealer serviced until 2008 @88340 miles , then sat in a back yard, i swooped the car from a buddy back in early 2011

i replaced the long block, milled the heads , ported the air intake,new water pump, full tune up ,new cats, lift kit,

drove it to Tahoe, Humboldt Chico a few times for off road trips /camping/snowboarding but was really unhappy with the bumpy ride dumped lift kit and went custom fox racing pro shocks with custom valving for my rover and now its so much better and ready for alot bigger tires and off set rims . but its stuck till i can drive in the snow and dirt with safe working brakes

also have done over 5 brake flushes the system was really nasty but now its dealer ship lot fresh.

 

A paperclip is all you need. First, if you know where all of your sensors are located take a 9/16 combo wrench lay the open end on top of the sensor. Take a small ball peen hammer and tap it on the wrench until the sensor bottoms out. You'll hear the tap the sensor makes when it bottoms out on the reluctor ring. That's all you have to do to "set" each sensor. To test the brain box you need a paperclip. Unbend it until it makes a U and then poke it into the number 5 and 15 ports on your OBDII diag port. Turn ignition on to pos II. The ABS light will stay lit after all the others extinguish and it may start flashing. The flashes will indicate where the brain is getting a fault.

And once you figure out what is wrong you can then try to fix it or just pull the ABS pump fuse from under the hood fuse box.
Find out what is wrong first, it might be as easy as Scouts says.

 

...and the ABS bulb from the dash card......

 

much thanks , gave up on my abs brain for the moment , also i now have defender front breaks , also after redoing my breaks i saw i do not have abs break pad sensors , so where are the abs sensors in the wheel hub?
