Can you please double check you have the correct pins. I also found that some new relays have a diode in them and they will throw a fault. The good old 12v 30 amp relay works best.
Cheers, TomI
I dont know old relay is. I am adding the relays I tried and cable colors to the photo.

Sorry for the late reply, I've been away.
The far right relay would be good.
Make sure you connect the relevant wires to terminals 85 and 86.
If you use any of the other terminals it will be an open circuit and the TCU will throw a fault.
It has to be 85 and 86 as this is the relay coil, and when connected to these terminals it tricks the TCU into thinking it is connected to the lockup solenoid. So when it does its own self diagnostic check it thinks all it well.
Hope that helps.
