Educate me on talking to wabco ABS

[aw113sgte]

I can talk to engine ecm, transmission tcu, Spicer CTIS. Wabco ABS seems to be a little different? Using Dearborn 3+ and can seem to connect over J1708 but wabco software doesn't really show much data, most fields are blank. J1939 doesn't seem to work at all. This is through the port to the driver left knee. I can't find mention of the connector that is next to the abs module itself (attached)

Trying multiple solutions, various computers with serial adapters and built in serial ports. Have the same returns from software. Everything else works perfectly, abs is the outlier. Tried following the instructions for changing between 1708 and 1939 (power cycle) and same results.
Is abs supposed to show up in the picture?

Is that the plug for the contamination sensor? ABS is read at the diagnostic port next to your left knee when in the driver's seat, no?

Doubt it, but maybe?
The connection I have is all through the left knee connector. Not sure if he connector by the ABS is direct to it or if I even have an adapter for it.

The ABS module is on the J1587/J1708 bus along with all the other modules and connects through the same diagnostic connector.

When you use the the Dearborn software, do you show abs module in this window? Will help ne narrow down hardware vs software issue.
