04 Dakota RWAL bleeding questions
I have an 04 Dakota with rear wheel ABS only. 2WD auto with V8. I have a Snap on Solus Pro. My only options to actuate anything in the ABS are a power relay, rear dump valve and rear isolation valve. I know a DRB will make bleeding easier. I don't have one. My questions are these.
1. The control unit is a single box near the brake cylinder that only has one line in and one out with a wire harness. If one wheel starts to lock I assume this unit stops it. How? I do not see room for an accumulator or a pump in this little guy.
2. Is it where all of the solenoid I can actuate are?
3. Is there any sequence to actuate these solenoids while bleeding and what state does the pedal need to be in during the solenoid actuation?
4. Is anyone familiar with using this tools for the bleeding?
This is all because there still seems to be air in the system after a master cylinder replacement. Yes, the cyliner was bench bled. Thanks for any help you can add.

The solenoids are the 2 vertical silver cans. The accumulator piston faces the firewall (i think) and is under one of the lines (input I believe). I wouldn't know as I deleted my ABS because I got tired of it's ^$#@. If it detects lockup or chatter in the ring gear speed sensor, it disables the brakes for both rear wheels (the single line going back).
