I get the below from the ABS Amigo, I have done the option B. I certainly could have screwed it up, the ground looks good to me. Any other way to test it before I pull the unit apart again?
logged Faults:
114:Shuttle Valve Electric Failure

I also get the below which leads me to think the RR hub is bad. I get the fault very intermittently, I know I should swap the sensors to see if it moves. Does the 020 mean anything?
020:No batt supply voltage
047:Rear Right sensor output low

Sometimes, less frequenlty, I get these:
012:Pump fail monitor line
035:Rear Right out valve open circuit
040:Pump relay open circuit

Thanks,

 

Whenever I've had a bad hub, it's always accompanied with the "Rough road, signal implausible" code.

I'd back track all your Option B connections. It's truly the easiest (and free) of the troubleshooting options.

(and obligatory "make sure your battery is fully charged" mention)

 

Prior to OBD2, a code 02 meant the battery had been disconnected. Maybe relates to the 020 question.

 

Ill pull apart the option b and see what I have. Somewhere I have the info on testing it, the voltage, etc when the valves are actuated.
