Typical immature douche bag response...

You are comparing a system that is more advance than what the S-chassis has. The ABS ECU see's ONE sine-wave from the rear differential, whether it is a 1/1.5/2way LSD or open-diff has no effect on the system. You don't speed up the differential by locking the two rear wheels together. There aren't TWO different sensors on the rear diff like the J30's. I understand what you are saying about the logic in the computer to compensate for two wheels vs one. However, the system is archaic at best, it activates both rear wheels simultaneously. IF it were a more advance system, it would have two seperate wheel speed sensors, brake fluid lines and two sine waves going back to the ECU, then yes you'd be right and I'd admit defeat.

Do you honestly think that people haven't installed other types of LSD's into the S-chassis ABS differentials before?

OP, was your light on after the diff install, before you started driving? Or did it come on after you drove? The ABS system does self checks after start up at low speeds, to identify any potential problems within the system. If it see's a problem, bad wheel sensor, no wheel speed registering, etc., it will shut off the ABS system, and pop the ABS light on your dash. Do you have an FSM?

edit: Came back after thinking about this. I realize we're not communicating about the same thing anymore. We're two dudes on the internet playing up to our imaginary stereotypes. In fairness, I apologize for sounding harsh. I'm terrible at the internetz, I just wanted a solid answer because you have trailed my last few posts.

You say the 3 channel system will work with a welded diff, I believe it will not. Where you say the 3 channel system is archaic and cannot physically detect a change in the vehicle braking dynamic through its 3 sensors, I say it can and was hoping you would prove that part specifically. From my understanding, ABS modules are programmed to handle a specific vehicle under specific conditions. Locking your rear end physically changes the braking dynamic. That in itself should be great enough for the ABS module to realize something is wrong and throw an error code. The FSM only explains how the sensors communicate with the ABS module (i.e. what you just posted).
