Here is the manual for the Series D ABS in my coach. The code says I have 6 modulator valves and 6 wheel sensors.

Bill, you posted that the code says you have six wheel sensors, but I do not have ABS on my tag wheels. In three years I have had two emergency stops and had to replace both tag tires twice. I have to wonder what the cost would be to add ABS to the tags.

I would think it would be a lot to retrofit ..but how do you know other than it not working?

Look at your ABS module and look for a code that looks like 6S/4M ...

The- manual attached to this thread says that you can have sensors on 6 wheels but brake modulators on either 4 or 6 wheels. The code will tell you what you have. It's right on the front of the WABCO controller.

Bill, I am lazy, where is the ABS module?

[bikestuff]

Its right under the driver in basement. It says WABCO in big letters on module.

I checked the code and it is 4
Today I checked the code on the WABCO module and it is 4S/4M. Thus, I do not have ABS on my tag wheels. This is an expensive omission since I will flatten the tag tires any time I have a serious emergency stop.

Here are generic ABS sensor replacement instructions.
