Update. I installed the new senor provided by Moser and I went for a drive same routine I have been doing. No lights. I came back home and waited an hour and went out again and at third gear the low trac light came on. Then after driving a little further all three lights came on the brake light, low trac and abs. I turned the car off and on at a light and they disappeared but came on again. This was last Saturday. I have not had a chance to update thread. This week I am going to go for a drive again and if the lights come on I have my friends abs scanner this time so I could see what code it is giving now. I am now leaning towards the abs module because with the codes given off the module rebuild website the code was for a voltage shortage. Slowly getting to a solution. Hope I find one so the lights will not irritate me. I will keep you posted.

So I went for a drive again. No lights..after maybe five minutes in fifth gear maybe 65-70mph low trac comes on and I knew the abs was coming shortly. Sure enough it does. So I keep on driving until I can find a spot to pull over. Run the scanner it shows two codes now. I will post the pics in a sec from mobile. I erased them and continued on and same situation again. I pull over and now just the first code. I don't erase it and turn the key off and then turn the car on and it's gone. Drove for another 5-10 mins and did not come back on. I am starting to think maybe it is the abs module. Any ideas on what to try next?? I read somewhere on one of the threads in reference to abs inop light that his light comes on when going over 60mph.

First code.
This the one I have been getting the whole time.

Second code. First time it came up. But did not read this code the second time.

If the low trac, brake and ABS INOP all come on then that usually points to the ABS module going out like you said. I actually have a spare 3 channel ABS module that I'd let go of if you end up going that route.

Fixed my C0056 tonight by wiping off the reluctor ring with a rag. The rear I am running had previously been run with really thick gear oil which I drained though never wiped out completely. Apparently it had stuck to the teeth causing interference with the speed sensor... must be pretty damn sensitive.

I just found what was causing my issues last night maybe yours will be the same. check the where the harness from the rear plugs into the box on the body on the left side right in front of the axle. the black wire on mine was broke where the factory had put it together. maybe that will help. mine was fine I made a pass at the track and the came on. I left and they cleared but came on again a few miles down the road.

Mine is still acting crazy. Now Im getting the inop light right when I start the car, but it goes off and stays off until I hit 60mph. Im really stumped on this one, as it all started when I installed the 12 bolt. Everything worked perfectly before that, hell I didn't even crack open the brake lines during the install.

Update...

I put a new to me used abs module. The abs inop light comes on between 75-80 mph now. And when i turn the car off and on it goes away. So I have a new abs sensor and different abs module. Guess that's the best I'm going to get it at. Now at the track would it be recommended to take out the abs fuse so there is no spongey feel on the brakes?

It has to have something to do with the sensor gap vs the reluctor rings. That's the only thing that could have changed in these installs. Im gonna do some more research, see what I can find out while I still have the stock axle here.

Appreciate any info...

Is the gap between the sensor and reluctor ring adjustable?

Randolph Ziskey

iTrader: (13)

I think the sensor is sent shimmed...I think the sensor can be shimmed down but anymore and I don't think it will read the sensor.

Whats even more interesting is that you have a 3 channel and I have a 4 channel, but with the exact same problem, with parts from the same company. Im going to measure the stock gap and will report back later on today.

I drove it yesterday to autozone to get oil for the truck and went for a stroll. Never came on but didn't hit over 75 mph either.

I'm having a very similar problem with mine. The problem seems to be the gap between the reluctor ring and the sensor. It seems to me, that if you're paying over $5000 for an axle assembly, you shouldn't have to troubleshoot your own ****! Moser is an engineering company and this is a known and common problem. The sensor is too short and the bung is not sized properly. FIX THIS!!!!! This is completely unacceptable as far as I'm concerned! I should not have to file down the sensor or the powercoating on my housing!!! Sorry, this kinda stuff just really pisses me off!

My ABS stopped working after my Strange 12 bolt install. I've heard of similar with Midwest chassis stuff too. So, its not just Moser. Bottom line is, these abs systems are finicky and it is hit and miss as not everyone has issues.

Have you had any luck fixing it?

Yep, ABS delete fixed it.

MWC has never had any issues with the original or new style 3ch systems. MWC was the first to release 3ch on a production 9" rearend.

The 4ch system seems to be a lot more sensitive to changes, however 95% of the issues we have seen or helped fix have been related to wiring harness or sensor problems, not the rearend.
