Hiace Overheating Coolant Leak

My 2002 Toyota Hiace (gasoline engine) is overheating badly, and the check engine light is on. Coolant is leaking, looks like pressure is too high. Could it be the control module? Coolant level was fine before it started.

Sounds familiar. I had a similar issue with my Hiace. Was it a connectivity issue with the control module?

Connectivity issue? Can you explain more? Where should I start looking?

Yes, a defective cable or plug connection. Check those first. If you're not comfortable, I'd recommend a workshop. Better safe than sorry.

It was indeed a faulty connector on the control unit! The garage charged me 95€ to fix it. Appreciate the help!
