Hello everyone, I have a problem with the Corsa C 1.0 2002 after 4 weeks of standing the car did not want to start, only after turning on the ignition the Check lights were flashing and the car with the key and relays fired under the bonnet and the throttle starter does not start. First of all,...

Clear all errors and do diagnostics after a night when you can't start the car. Check in real whether the system recognizes the key.

Hello. Please charge the battery with the rectifier. Check after installing the battery what is the current consumption of the car's electrical system.

error with immo cannot be deleted is active all the time or can it be damaged motor driver? Because immo would not cause what is happening in the film Added after 1 [minutes]: Aku is fully functional and charged, so I didn't check it

Hello. What is the voltage drop when turning the starter.

This is first. On what basis do you say that? Well charged but not functional.

Give this battery a break. If he was out of order, he wouldn't spin.

Aku is functional so there is nothing to continue this thread someone will prompt or have a graphical mass list

Check the power supply on the engine ECU if you have full voltage at all. Does not die on one of the rhythms of throttle knocking.

If it gets a little looser, I will take measurements from what I know, when starting on battery and in the fuse box, the voltage drops from 12.7 to 10.5 so I think Oki

for me in 1.2 it helped to supply power from the battery to the relay from the ECU.

Hello everyone, I have a problem with the Corsa C 1.0 2002 after 4 weeks of standing the car did not want to start, only after turning on the ignition the Check lights were flashing and the car with the key and relays fired under the bonnet and the throttle starter does not start. First of all, I cleaned all masses under the bonnet, it got better because the relays stopped and once in 5-6 firing attempts the engine is surprising, once it works properly and sometimes it doesn't maintain speed. idle only about 500 rpm it doesn't go out you can go, nothing happens after 40 km, it fires up as if nothing happens after a night of standing, the problem returns. Adds movies and trouble codes maybe juk someone had such or similar problem
