iQ parking aid failure

I've got a 2015 Toyota iQ (electric engine) with 90k on the clock. Recently, the parking aid has completely stopped working. The display is dead, and I'm getting an error message stored in the ECU. I've looked at the sensors themselves; they seem clean and undamaged. Could a dodgy connection be the culprit?

I had something similar happen in my iQ. The parking sensors just went kaput. Before you tear everything apart, check the wiring harness and connectors. Are you sure all the sensors are actually clean?

Cheers for the tip! By clean, you mean free of dirt, right? I gave them a quick wipe, but didn't do anything more thorough than that. Was your issue intermittent, or did it just fail completely like mine?

Yeah, just a quick wipe won't cut it. Road grime builds up. Mine went completely, like a lightbulb blowing. Ended up being a corroded connector. Unless you're confident with electrics, it might be worth getting a workshop to take a look. Save yourself the headache!

Thanks, that's really helpful! I'll give the sensors a proper clean and check the connectors more closely. If that doesn't work, I'll get it booked in. They quoted 95€ for checking the cable or plug connection. Hopefully, that sorts it. Appreciate the advice!
