@ddietr there is no sound any more because of bad comments on my voice / speech
but for your jeep : are all sensors good ? just measure them is the pump allright ? just put power on it (12 volt ) and if your unit is an ATE unit it could very well be this problem
@martijnbaarn that is bs man.. i have an actual speech issue, crazy people would bitch when you are helping... where is this module and do i just saw it open and check/ solder the connections? shop wants $944 to replace pump, ecu, but there is nothing wrong with the pump.
@mdsuave13 the module is fitted under the actual ABS unit , you can remove it without draining the brake fluid . you need a little socket and get the 4 screws out . (look with a little mirror ) then it's pretty much sawing , soldering and there you go .
its the pump connector wich fails .pump motor and unit never fail to operate.
i wouldn't pay either so thats why i got into this .
@ddietr yes it could be this unit but that has nothing to do with excesive pedal travel , there must be some air in the system , i know the abs systems are very hard to bleed and get them air free. dealers electronicly manipulate the pump to get the air out .
@jfnovae i apologize for answering very late :P but the sensors are easy to install .
a professional mechanic should do one sensor in less than 20 minutes a diy mechanic should do it in half an hour , the sensors are easy to change and no further precautions should be made other than secure your vehicle when working underneath it !
I have a BMW 545i SE. The ABS light, Handbrake light, Traction control light stay on all the time. I spoke to the garage they say I may need a ABS module or a speed sensor. The steering wheel is perfectly aligned so I suspect it wont be the sensor anyway plus the 3 lights being on all the time. Is there anyway I could fix this myself?
@martijnbaarn How about the 3 lights showing up on the dash. Is it likely that it may need the whole ABS unit? The lights relate to braking, probably work in conjunction to all.
@esjayay you should get rid of all the other lights before you can diagnose the abs system .
basic systems must be good and checked . the rear brake shoes and front brake pads must be in a fair condition . the brake fluid must be at the specified level and the sensors should all be in reasonable state.
the hydraulic units on a (grand ) are very strong and pretty much bombproof (unless water got in it )
I would like to extend a huge thank you to martijnbaarn for this video and instructions. The ABS light in my 97 Jeep Grand Cherokee was coming on itermittently for several months, then come on and stayed on. I followed these directions and the light is now off and the ABS brakes are working. The problem is that the solder around the positive terminal oxidizes and the connection is lost. Re-soldering the terminal to the circuit board solves the problem. See next post for some tips.
@mishnishfourseventy1 thank you for sharing your experience , in your case i think you should recheck all connections and plugs etc sometimes the pump connector breks the new solder when you put it back on .
so i could be you have to do this again , another thing is the relay under the bonnet . you should tap on it or change it with the ac relay to see if it is broken or damaged
Ok I did this. My ABS light was on continuously, so I assessed everything else, wheel sensor resistance, signal, pin outs at the module etc and it all checked out. The pump also powered up when I connected it direct to the battery. This led me to conclude that the module was at fault. I opened the module and saw a burnt and cracked solder joint on the pump power connection. I re soldered it and put it all back together. Incredibly everything started working normally!!! see next....
I tried this on a 1997 grand cherokee. Commentary would have been nice but I figured it out from the video and description and it DID indeed work! I DID have to bleed the brake system up by the ABS module still (no big deal) Thanks for the video it saved some money!
@timal74 Just FYI if you are trying this. If you are looking at your terminal that controls the pump (like in the video), mine was some what burned and the solder was cracked around it. Re-soldered and it seems good to go
@timal74 yes you can see clearly what's wrong wit the terminals , i looked to them trough a microscope and they were crakced all the way which causes the pump circuit to fail and give you the amber light .
did you know this method often works on other devices from cars etc where strong currents go over a cicuit board
"after you succesfully removed the silicone layer , you should clean the board a litlle to make sure your new solder properly connects to the board." Where does the soldering come in? Is there a part two to this vid? Could you show a pic of the module attached to the vehicle? What are the symptoms other than the code for "pump circuit failure"? Could you narrate this vid? I see you touching different points and don't know why? I am a '95 Jeep Laredo 6 cyl owner and no mechanic. TKU!
@curtbeginner i'm sorry there is no sound in this video (and you won't need it also ) this works for ATE brake modules only , this is a repair when you get the ""pump circuit failure "" code (on a jeep ) but if your tahoe has an ATE module it could be the same easy repair . first check simple things like fluid en broken wires .
then measure each sensor (should be around 1120K ohm each ) then simply put power on your pump motor , when it starts running your motor is good .
@martijnbaarn also check for broken fuse etc , if nothing else seems broken maybe your module is broken .
90 % of time the connections are loose inside the module , just open it up carefully and see what's inside .
but a broken sensor is what happens most (all sensors should read around the same resistance , if not the lower or upper measured value is the broken one )
ddietr: i have the same problem but my abs stopped working and the abs light and brake light is on.

I have no sound.
We have 2001 JGCL 4.7 L V8 . We replaced all calipers and Master cylinder.
Could it be this unit ? The pedal goes half way to floor before engaging.

@esjayay by the way the cruise control is not working too.
esjayay 3 months ago
@esjayay the cruise control uses 1 sensor in the gearbox and it uses the wheel speedsensors which are also the abs sensors .
if your abs is not functional your cruise control can be out of function .
so check your wheel sensors (resistance should be 1120 kohm ) or replace the gearbox speedsensor.

@delambert thank you i'm very happy to know my video was usefull for you .
this was a really easy and cheap repair, i think so ? the official jeep dealer does not even know this and always replaces the whole part for much $

but then after 1 day the light came back on. Do I have to take it to the dealership to reset a code or is there something still wrong? please help!!!
