Maybe that goes back to the fact I can’t link to the ECU?

Good question, I don’t think so. I checked there was fuel going to the engine and there seemed to be; and at a high pressure, but honestly that probably means nothing. Might need to get someone in that has a proper professional code reader.

Hey all, this is where I’m at… currently we’ve tested the lives on the ECu and cleaned the earthing around the engine. We’ve tested the wires from the ÉCU to the injectors and we seem to be getting power to the injectors, the fuel pumps are also working. I’m stumped, maybe I’m missing something...

Great help thanks @Mark Piercy , this level of electrical maintenance is above and beyond me, I’m good with mechanics, not so much fuses and wires haha. Really hoping I can get this beauty going!!

Just noticed you're in Poitier.. I'm 2 hours south of Bordeaux. Looking now thanks

Got it working with a PDF version, but I can't find the wiring diagram for the ECU connectors. I basically need to figure out if the lives and grounds are working.

Ok, I got it working, but I can't seem to find the ECu wiring diagram, I'm sure it's me at fault. haha

@brianp38dse I'm on a Mac, struggling to get acrobat reader to open it

Legend thanks @brianp38dse !!!

Just the connections to the ECU

Don’t laugh , but I don’t know what that is haha (apart from great party)

Hi all, been searching but no luck, looking for a wiring diagram (specifically for the ECU) for my 2005 td6 (M57) HSE Range Rover. Thanks in advance!

Hmmm. I just realised the earth i cleaned today was not the earth strap, got the location wrong, going to try tomorrow again.

Silly question maybe, but what’s the best way to check the power and ground for the ECU? Thanks

Will check the model but it’s an icarsoft, it’s my mates he has it for his discovery… I’m pretty sure there’s power at the ÉCU, it’s turning something on in the engine when you turn the ignition on, a whirring noise which lasts for about 20/30 seconds (my mate told me that’s something that the...

Hey all.. UPDATE, so battery arrived and I trickle charged to full, fitted to the car and sadly, nothing changed, a couple of codes popped up including U0401 (invalid data received from engine control module/powertrain control module) and U0402 (invalaid data received from transmission control...

Oh interesting, I assumed it would arrive fully charged

Don't mind the HDC thing... just need the car to start haha.

Yes, can't wait till it arrives, praying haha.
