I don't see in any posts that the Diode in the fuse panel was checked out.
I checked the provided power as mentioned in the ECC Relay Function and location Doc above: All as mentioned except Terminal D. Ignition off was correct but Ignition on only ~3.3 Volt, it should have near 12V!
I checked the diode and the relais but nothing special besides the lower voltage.I don't see in any posts that the Diode in the fuse panel was checked out.
Don't know how the DIODE was checked. But here is how it should be. With a VOM set on 200K Ohms, with the (Red) lead on one side and (Black) lead on the other side, there should be a reading of Hi Ohms, then reverse the leads and there should be NO reading, if you get a reading in both directions or NO reading in either direction, that Diode is BAD.I checked the diode and the relais but nothing special besides the lower voltage.
My mechanic will check what happens after a change of the relais.
But beside that, I don´t understand what an defect ignition switch has to do with an non changing gear in the tranny? Note the tranny is going in forward and reverse. But only in these 2 gears. I would guess if the ignition switch fails you will normally still be able to us the tranny.
So long time no see...
My truck is now at one of the biggest Ford Dealers in Germany. That generally means Ford Europe, of course. Witch actually means nothing.
knowing everything that was discussed here so far - the chief decides to "fix" harness to get a proper reading of the electronics with his tools........
So far costs for that would be some thousands of US $
So this means for me: I need a new one (mechanic) - or fix it myself - or set the bloody Van on fire ...
...or find another solution. As no one seams to be able to have any clue how E4OD and Truck harness and the ECU/TCU work together - I have an idea of using a stand alone Transmission driver, of module.
I´ve seen these exist also for the E4OD and cost for these are starting from roughly 600 US + harness. Has anyone here real world experience with these modules? Would / could this be a solution?
So I checked all fuses, none was defect. The ECC Relay is removed at the picture and was located near the 20A fuse.
I checked the provided power as mentioned in the ECC Relay Function and location Doc above: All as mentioned except Terminal D. Ignition off was correct but Ignition on only ~3.3 Volt, it should have near 12V!
Not sure if this could cause the problem? And I have no clue why there is 8 Volt "missing"?
