CHR Terminal 15 Ignition Interrupted

I'm having a terrible time with my 2019 Toyota CHR Hybrid (172174 km). I keep getting an error, and the engine won't start. I've checked a few things, but I'm not mechanically minded. The diagnostics point to a 'Terminal 15 ignition positive interrupted'. Could this be a simple circuit break or a battery terminal issue? It's driving me crazy!

Ugh, electrical gremlins are the worst! 'Terminal 15 ignition positive interrupted' sounds like a power supply issue to the ignition. Could be a faulty ignition switch. Have you checked for any voltage drop at the switch itself when you try to start the car? Had a similar issue on an old Ford; it took ages to find a corroded connector.

Voltage drop, huh? How exactly do I check that? And where is the ignition switch located, precisely? I'm guessing somewhere near the steering wheel, but I don't want to start pulling things apart without knowing what I'm doing. I once messed up my radio trying something similar!

Yeah, the ignition switch is usually near the steering column. Honestly, chasing voltage drops can be a pain without the right tools and knowledge. Given the 'Terminal 15' error, and the fact that it won't start, I'd strongly suggest taking it to a workshop. They have the proper diagnostics gear to pinpoint the exact location of the cable or plug connection defect. Save yourself the frustration.

You're probably right. I think I'll book it in. Just got the bill today: 95€. Turns out it was indeed a faulty cable connection as they predicted. Thanks for the advice, I appreciate it!
