Might have to reconfirm this statistic, this does refer to half-ton models correct?

Some interesting findings...

I ran a scan on all the modules, after the scan started, I got the "Service "Stabiltrak" message on the DIC.

Final results were 2 codes,

Rear heated seat module B1925


C0045 left rear wheel speed sensor.

Safe bet the speed sensor will mess things up.

Next, I checked the blue blunt cut wire under the dash for continuity to the 7-pin and there was none. Nothing to the 6-pin connector at the relay above the tire, or to the 7-pin.

Also, the mystery relay under the brake booster shows no continuity to the blue blunt cut wire.

I'm assuming the wheel speed sensor was acting up but hasn't stored a hard fault yet.

Yes.

Is the C0045 an active or historical code?

I don't think those wires are original. 2009 was an intermediate year and that is why I asked some of the guys with newer trucks with JL1 to chime in to see if they have that stuff.

I'm going to guess an active since I have run this test a few weeks ago and there were no codes. Interesting about the seat heater also.

This was the screen.

I'd be curious where these underdash brake controller wires are disconnected if you have the JL1 (ITBC) option and if it's just a plug type connection where the other is plugged in and just needs to be swapped
