Fortuner ignition error

Hi, I have a 2022 Toyota Fortuner, diesel engine. I'm getting an error: 'Terminal 15 ignition positive interrupted' and the engine won't start. The error is stored in the memory. Could this be a cable issue?

A 2022 Toyota Fortuner with a diesel engine is experiencing an ignition error: 'Terminal 15 ignition positive interrupted,' preventing the engine from starting. The error may be due to a defective cable or plug connection, possibly involving the power supply to the relay switch. It is suggested to have the wiring harness checked at a workshop to resolve the issue.

I had a similar problem with my Fortuner. The error code pointed to a defective cable or plug connection. Did you check the power supply to the relay switch?

Thanks for the quick reply! Where exactly is the relay switch located? Is it in the fuse box, or somewhere else?

It could be a fuse box problem, but in my case, the wiring harness was the culprit. I suggest you take it to a workshop to get it properly checked. I paid 95€ to fix this issue.

Thanks! I appreciate your help. Will take it to the shop to check the wiring harness!
