ES Parking Assist Failure

I had something similar on a different car once. That error code is key. Usually, it's just a bad connection somewhere. Have you checked the plugs and cables going to the sensors? They get corroded sometimes.

Thanks! Any tips on finding those connections and what to look for? I don't want to start tearing things apart without a clue.

Usually, they're right by the sensors, behind the bumper. But it's a Lexus, so who knows. If you're not comfy with electrical stuff, and you already have the error code, a mechanic might be the way to go. The code will speed things up for them. Could save you a headache. I messed something like this up once trying to DIY!

Good call. Took it to a shop. Turns out it was a bad cable connection, just like you said. Cost me 95€, which isn't bad. Thanks for the help!
