IPace Air Con Valve Block
Posted: Sat Jun 18, 2022 2:12 pm
Just bought this I-Pace air con valve block:
I'm fairly sure all the valves come from Sanhua Automotive (https://www.sanhuaautomotive.com/produc ... ion-valve/)based on the logo on the electronic expansion valve. While the valve I have doesn't look quite like the one on their web page I think it is probably the previous generation as there are a few pictures of a similar one on the web linked to Sanhua.
The larger valves only have Jaguar marking but I think they are electric ball valves also from the same company (https://www.sanhuaautomotive.com/produc ... all-valve/). Again they don't look exactly like the picture but similar enough, and with the same connectors, to make me think they are older generation Sanhua parts.
I can't find any information on the electrical interface online. While I could sacrifice one of the valves to work it out (the case is glued/plastic welded shut so would need cutting open) I'd prefer not to if possible.
All current Sanhua parts are detailed as having either both LIN and PWM interfaces (expansion valves) or just a LIN (ball valves) so LIN seems a likely candidate.
Does anyone have any tips for identifying which pins are power and which are comms, or a good process for hacking LIN bus interfaces?
Hoping to use most of the bits off it but need to figure out the valve controls - does anyone have any experience or information on this type of valve that they could share?I'm fairly sure all the valves come from Sanhua Automotive (https://www.sanhuaautomotive.com/produc ... ion-valve/)based on the logo on the electronic expansion valve.
