I own a 2004 Impala. For 3 years I got intermittent TRACTION / ABS warning
light errors which would come sporadically. I had both front hubs replaced
at a cost of over $750 and they would just keep coming back. Seemed like
whenever I backed out of the driveway or turned a sharp corner or hit
bumps… one shop told me it was the ABS controller and that would cost
$1400 alone just for the part. I finally checked You Tube and forums and
dissected a wiring harness of a wrecked Impala and concluded it MUST be a
connection. There is a TSB out there for wiring harnesses to rub against
the AC dryer unit and eventually short out but mine wasn’t doing that. It
got so bad that the ABS motor would sporadically come on even when driving
down the road. The ABS computer threw 3 codes at me – C1225, C1226 (ABS
sensors both sides) and C1216(ECBM issue). And it happened on every bump.
So I knew it must be wiring. I finally got my daughter to sit at the wheel
with the car running and let me know when the warning lights go off… or
she feels the steering wheel vibrate from the ABS pump. So I started
wiggling wiring and connections all along. You know what it turned out to
be??? A simple connection! The connector where the ABS wheel sensor
plugs into the main wiring harness for the car! I pulled it apart and it
was corroded green inside. Salt must have gotten in and corroded the
terminal. I also noticed that the harness had little slack and when you
cranked the wheel all the one way, it almost pulled apart. So I hit the
connections with penetrating oil and rust preventor oil (Krown) and pulled
some slack from the main wiring so the wheel could turn but not pull apart
the connector. No more problems. A simple rusty connection was causing the
computer to throw 3 codes, and cause all this annoyance! It makes sense
you know – cause they would replace a whole hub, and 3-6 months later it
was acting up again. Why? Because when they disconnected the old one and
plugged the new one in, it took that long to get corroded again. So its a
bad connector design. I took some silicone and sealed the holes on the top
end of the connector harness, so as to prevent salt water from draining in
again. I would check the front two connectors and see if they are simply
white/green corroded and go from there. I would also crank the wheel all
the way to each side and see if the connectors start to pull apart… could
need more slack. I suspect these harnesses are pretty common on most GM
products too. Hope this helps!

This video is USELESS for what the titles promises!
It should read: ‘ABS Sensor & Tone Ring FUNCTION and MAINTENANCE’
and NOT: ‘ABS Sensor & Tone Ring Repair’

Great channel. You hit on some core topics like Ethanol in gas, less zinc
in new oild versus older engines, shocks vs struts
Try going to Bavarian Auto website. Ask them about your issue. Go to
Bimmerforums and ask around. You can find plenty of help in forums.

I have an 88 Mazda 929. I don’t have ABS. I replaced my brake booster no
problem with the non ABS model. When I tried to replace my rotors, I
ordered the non ABS rotors and they did not fit. I have to order the ABS
rotors because the lugs are attached to the rotors. Why is this? Just
inquiring.
because brake fluid is hydroskopic
Good tips Thanks….
