Or you can try this I have is saved off another board.
ABS DIY to save some big $$$$
Itīs been a while since my last post still bot my truck
just havenīt done much to/with it lately.
I donīt know who is subscribing to the chevytrucks group @yahoogroups.com but I thought I should share this with you as how to fix your EBCM (ABS) module if you have some soldering skills past that from soldering pipes etc.
If not there are some guys that will do this job for you for $100 plus shipping: http://www.circuitsolutions.info/
But here the DIY version:
"When you look at the control board, you have your 12V input and 12V out to
the small motor. The MOSFET is the larger one close to this 12V out. The
one that was in mine was a Philips BUK9608. I replaced it with an
International Rectifier IRL2505S. You can order them form DigiKey.com part
Replacing it is the easy part, its getting to this guy that is hard part.
From the factory, the circuit board is dropped in the housing and then
soldered in. So you will have to unsolder the 12V power pins, the 12V power
pins out to motor, and the sensor connector pins (about 10-12 pin connector)
before you can remove the circuit board from the housing.
If you go through all this effort to fix the problem, do yourself a favor
and solder a diode across the "12V out to the small motor" (like a
FR302DICT-ND from DigiKey) to protect the MOSFET (band towards the positive
