370Z tail lights switching on intermittently

I had a similar problem with my 370Z a while back. The symptoms you described – tail lights switching on randomly and an error code – sound very familiar. Have you checked the cable and plug connections of the light switch itself? Sometimes a loose or corroded connection can cause these kinds of electrical gremlins.

Thanks for the quick reply! I glanced at the connections, but didn't really investigate thoroughly. When you say "cable and plug connections", do you mean where the switch plugs into the wiring harness behind the dashboard? Was yours obviously loose, or was it more subtle?

Yes, I'm referring to the connection of the switch to the wiring harness, which is located behind the dashboard. In my case, the defect was a loose contact in the connector itself. However, due to the error memory and the overall complexity, I would advise you to have it checked professionally in a workshop. My expenses at that time were 95€.

Okay, I understand. Thanks so much for sharing your experience and advising caution. I'll take it to a workshop and have them check the connections and the switch itself. Turns out the repair cost matched yours. At least I had an idea of what to expect!
