ABS PUMP IS ALWAYS RUNNING

Thanks for this video! Fixed my abs light issue 🙂
what hell is being used to solder it. anybody know
Way too much gasket sealer and you didn't actually clean the 2 surfaces for proper thickness thermal pads because there's a gap between board and plate.The paste you used is meant to be completely displaced between contact areas like on a CPU, and otherwise you won't get good heat transfer.
If I was confident that this was my issue (abs always, Brake light sometimes) I would try my chances at soldering again but I suck at it. Hit a deer tonight, while trying to stop I blew my brakes and pedal went to floor. So I decided to just buy a remand one unfortunately since I have to bleed brakes now anyways. I will try my luck on it after I have it off the vehicle and inspect what caused it to fail.
Worked like a charm. Thanks for the insight
Would this cause a transmission to go into limp mode? I have the same symptoms but also my transmission is in limp mode.
what an amazing piece of electronic ….
Are you stilll repairing these modules. I have a 2002 gmc 1500 with brake and abs light
Hello, are you use a heat gun to melting a glue to easy open a cover? I also have a problem with abs light intermittently triggered.
Hope you can answer, tq
Will any thermal paste work for this or should I look for the HY510 thermal grease? Also, what gasket sealant is that?
So, basically, the solder points on the board slightly separate and require better contact?
What was the problem, that prompted this repair?
