L322 Driving me crazy now

so today I phoned a local landy specialist. Took the l322 over and he couldn’t access the EAS either.

So he very kindly printed me the wiring diagram for the EAS ECU.

So symptoms I have are:
She leans to the right. Front and back drivers side are both low but not on bump stops. EAS is in hard fault, no lights anywhere.

Now so far I have tried the following:
Checked all fuses/relays,
Checked all connections,
Rebuilt compressor just to be sure and replaced relay,
Tried disconnecting ECU’s to find out if they are blocking the Can Bus signal. The ECU’s I have tried are:
Headlight Levelling,
ABS,
Even tried it with the steering angle sensor disconnected!

The fault codes I have are
SAS ECU:
Steering Angle Sensor Circuit, (been calibrated and works fine on graphing)
Steering Angle Sensor Battery Voltage slow (new battery and always starts and charges fine)

ABS ECU:
Air suspension can error,

No matter what I do, the can error will not clear nor can I access the EAS ECU. So I have bought a used one from a breaker on eBay. After that, I really don’t know what to do. It must be a loom fault!

Any thoughts anyone?

What was he using to access EAS ?

Don’t know but he said there is no reason he shouldn’t of been able to connect to it unless I had a fault. They are quite a big specialist in Land Rover
