2SZ-FE - Toyota Yaris II 1.3 does not turn the starter, the buzzer relay under t

Hello.

Toyota Yaris II 1.3 VVT-i 2006.
XP9F (A) SCP90 (H) SCP90L-CHMRKW (1A)
VNKKL98320A083211

The fault suddenly appeared.
I get in, turn the key and this relay starts buzzing:



It is located under the hood, on the left, behind the battery.
It buzzs all the time when the ignition is on, and after pressing the clutch (until the sensor operates) it stops buzzing. The car does not start, does not spin the starter at all.
The lights on the board are lit but not all. No charging icon, engine ...

I checked the fuses. Battery is full. What to check next?

Engine weight.

Oh gosh!!!! You're right. I made an abbreviation of a battery welding wire and it works.

Wow, that's great ?

Thank you for your help.
The culprit turned out to be the untightened ground cable on the gearbox body.
