96 R ABS module - again

Post by **Clemens** » 11 Jun 2016, 06:45

So i boighz my R with abs and tracs light on. Cut the module open, found the main power supply solder joint cracked, soldered it and sealed evrrything with a rubber sealer for electronics.
Lights never came on till today. Now i have a permanent abs and tracs light right after startup. Where do i start looking for a mistake? Also, i need to mention that a?few weeks ago i had abs action on the front left or rear left wheel when braking hard and turning at the same time. Checked all wired and abs rings and they seemed alright. But of it were a sensor or a ring it would most likely not?illumnate the abs and tracs right after startup but after moving, right. Any ideas are welcome.

Open it again and solder every pin to the PCB on that end of board.
The lamp is lit for every fault. The common ones are power supply/pump faults and wheel speed circuits.

You can't just resolder one joint, you have to do all of them.

Thanks, Matty, I wasn t aware of that. I thought looking for one broken solder joint is the way to do it. So I will resolder all connections and hope that does the trick. I'd send it out to you, but s&h back and forth is a small fortune.
