The entire Corsa Evolution 1.8 travus is turned on

Hi everyone, I need your help. I have a 2004 Corsa Evolution 1.8. The problem is that when I turn on the parking lights, all the dashboard lights come on. This happens when the car is off, but they turn off when it's running. Has anyone else experienced this? Could you help me? Thanks in advance

Hello.
The problem you're describing is very strange, since the only difference between the two states is that at one point the lights are being powered by the alternator (normal condition), and at the time of the problem, they're being powered by the battery.

What I would have expected is that when the car is off, the parking lights on the dashboard would dim, making it seem like all the lights are on due to a low battery.

I would ask you to confirm the problem.

I already checked what you mentioned, and it's not that. It's quite strange, and I don't know what it is anymore. When the car is running, I press the parking lights, and it works perfectly, but the moment I turn it off, all the dashboard lights start flashing, and even the fuel pump indicator comes on in sync with the parking lights. I thought it was the relays, but it's not, and I'm afraid the fuel pump will burn out. This only happens when the car is off. Thanks for your response

Scan it, scan it, and scan it

Hahaha, like a disco! Look, when the Hazard is on, check the fuel pump ground. If it's flashing, your problem is a ground issue, nothing else. Good luck!
