Allion electrical malfunctions and error memory issues

Whoa, that sounds rough! I had something similar happen with my Allion. Not sure what year mine is, but it's also a Toyota, and I remember error codes popping up like crazy. Did yours start after any specific event, like a service or a software installation gone wrong?

No recent services or installations, that's the crazy part! It just started out of the blue. The error memory is flooded with errors, do you remember if you had the navigation failure too?

Yeah, the navigation was totally dead too! The whole thing was acting possessed. Honestly, I tried a few things myself, but in the end, I just took it to a workshop. They re-flashed the ECU, and that fixed everything. Saved me a lot of headaches!

Sounds like I'm resigned to the same fate! Thanks for the info; workshop visit it is. Hopefully, a simple software re-flash will sort the mess out.
