Moser 9 ABS Inop

[RichWS6]

Hey everyone, just a quick question I have a moser 9" rear axle on my trans am (3 channel no trac ctrl) and whenever I drive about 5 or 6 miles I will get a low trac light followed by the ABS Inop light, I checked the sensor it self and it is the proper distance from the ABS ring and the third brake light bulbs are both in working order. Is there anything blatantly obvious that I am over looking? or a next step forward for tracking down what my issue is?

Have you checked your brake fluid level? I don't know about GM cars, but some vehicles will get an "ABS INOP" light if the fluid level is low. Also, are you running the same diameter wheels/tires? Another question is did the sensor come with the new rear? Or did you swap the factory sensor onto the Moser?
