RABS Control Module

[geno8769]

I did a search but didnt find anything helpful.

I have great feeling brakes, I have replaced the RABS ByPass Valve and the RABS sensor in the rear. But I still have the Rear Antilock light on. I made a panic stop today and I KNOW that the rears are locking !

How do I troubleshoot the control module, I found something for troubleshooting the earlier gen RABS, but nothing on the my truck.

Any suggestions would be greatly appreciated.

i have the same issue well brakes are that great there is a sensor that plugs into the master cylinder that i think is tied into the abs light but im not 100% sure if it is tied in to that or not

A bad vacuum sensor (tuna can looking thing) I believe can also activate the Rear ABS light.
