I am rather new to this site and I also posted this in the Ford econoline van forum. I Hope I am not breaking any posting rules!

This is an open circuit code

I have inspected the wiring harness and found nothing peculiar.

What I did find, is the ABS module is a F7UA-2C346-AC and I cannot find this part anywhere on the internet. It does not match what OEM e150 says it should have F8UZ-2C219-AA

It's made by Kelsey Hayes. it has 3 connections on it. It has a 20 pin connector from the wiring harness and another 2 blade connector from a harness. It also has one more 2 blade connection with wire going from ABS module to pump motor.

I have voltage power to the ABS module and also voltage power out of the ABS module to the pump motor.

Any Suggestions for additional testing?
