Hello again,
I found the problem. The switch from the brake pedal was broken. The hydraulic switch from the brake pedal for this truck is normal close and when the brake the contact is open. From the bigining I was wrong because I supose that the switch is normal open :((.
Thank you for support.
Best regards.
