The results of your diagnosis are interesting. Please write back as soon as you do
CAN bus = Controller Area NetworkHi All .. ......
I am suspecting a comms issue and my tech man can check the CAMBUS ( canbus?) ..
New ECU .. sale or return ( at a cost) no change to situation .. still a full dash of warning lights, so the actual ECU apparently not the problemYeah, step 1 is confirming that the power to the module is making it there.
First, check that the fuse is good, then remove the connector from the module, and test with test light and dvom on the correct wires/pins.
Pine Hollow Diagnostics is good, but I much prefer Eric O from South Main Auto.
Any ideas of which pins are the power input and grounds?? And the expected voltages ⚡I would check for ECU voltage first, then ground continuity.
Aha .. yes i know this fuse box .. same place on a UK spec car.. 2 screws hold the top on.. will take a lookSorry, I don't have any schematics. I remember that I have used a fused ECU/Trans power for the grill V Led lights. That is located in the engine compartment(passenger side in US). I don't remember which one though. It was a tiny 10A fuse, toward the front of the car. It should be there, where the arrow's point is. View attachment 30458
Another fuse box towards the front of the car .. this is where the relays and fuses seem to be. If I feed power to the ECU relay ... it ( the ECU) powers up and diagnostics can get in. But there is now power getting to this relay from the loom ... fuses all seem OKAha .. yes i know this fuse box .. same place on a UK spec car.. 2 screws hold the top on.. will take a look
