GX turn signal error

I'm extremely frustrated. My 2006 Lexus GX with a gasoline engine is showing a turn signal error. The error memory is storing the fault, and it's displaying an error message on the speedometer. It's clearly a lighting fault. I suspect a defective cable or plug connection. Has anyone encountered this?

I had a similar issue with my GX. Check the flasher relay; it's a common cause. Also, inspect the bulb socket for corrosion. I have seen this before.

Interesting. Could you elaborate on which specific flasher relay you're referring to? And where exactly I should be looking for corrosion in the bulb socket?

In my case, it was the flasher relay for the right turn signal specifically. Corrosion was visible right where the bulb connects in the socket. Given the symptoms and your suspicion of a cable fault, though, taking it to a workshop might be wise. I ended up spending only 95€ for the repair.

Thank you for the insight. I appreciate you sharing your experience. I had the issue resolved at a local garage. Turns out it was indeed a corroded connection at the bulb socket, as you suggested. Appreciated!
