MR2 Ignition Interrupted

Greetings. I understand your predicament. I encountered a similar issue with my MR2, although the circumstances may differ. The error code suggests a potential problem with the power supply to the ignition system. First, have you inspected the relevant fuses in the fuse box? A blown fuse could easily cause this interruption. Furthermore, scrutinize the cable connections leading to the ignition switch. A defective plug connection can manifest as an intermittent or complete loss of power.

Thanks for the quick reply! Yeah, I checked a couple of fuses that seemed related, but I'll double-check them all tomorrow in daylight. Which specific cable connections to the ignition switch should I be focusing on? Any particular wires that are notorious for causing trouble in MR2s?

Acknowledged. While there isn't a singularly notorious wire per se, focus on the primary power feed to the ignition switch. This is typically a thicker gauge wire. Examine the connector itself for corrosion, loose pins, or any signs of physical damage. Given the error code and symptoms, and considering you've already checked some fuses, it appears the 'likely cause' from your initial assessment, namely a defective cable or plug connection, warrants careful investigation. However, and with all due respect, if you're not entirely comfortable diagnosing and rectifying electrical issues, it might be prudent to consult a qualified automotive technician. A systematic approach and proper diagnostic tools are essential to pinpoint the root cause.

Took it to my local mechanic. Turns out it was a corroded connector. They cleaned it up, and everything's back to normal. Cost me 95€. Thanks for the help!
