Hello,
Does anyone know for fact if any year S2K had true 4 channel ABS? If so, do you know what year it came with 4 channel and what the part number is for the modulator assembly unit?
Any help would be greatly appreciated!

 

MY 04 has 3 channel and MY 06 has 4 channel. I don't know about 05 but I think 4 channel ABS was included when they introduced VSA in 06.

 

Is there a big difference?

 

On the three channel ABS on the earlier cars, I understand that there is one channel for each of the front two wheels and only one channel shared between both rear wheels.

Does anyone know if the fourth channel on the '06 and newer S2K's is to allow each of the rear wheels to have their own braking channel or is the fourth channel for the VSA?

Does anyone know where I could purchase the ABS modulator from an '06 or newer?

 

i sure the 4 channel is for each wheel since it can brake each wheel independent from each other due to VSA
