Thanks for the update, it appears the test points are is now reading correctly. The controller is OK on all the basic functions.

Moving onto the next diagnostic work:

A few question first to help me:
1. When you do the SYS test, does the red and yellow led comes on on the controller.
2. SYS test: Did the system spray?
3. SYS test: Did the gauge show flow?

Next test for the green led:
4. Unplug the red and blue harness to stop the pump and FAV from activating.
5. Unplug the green harness.
6. Ground the green wire of the ECU harness (grey) and tell me if you all the leds come on on the controller.

Await your reply.
