MAN TGA 35.360 - error code ZBR 01087-01

Hello.
In the company in which I work, a colleague driving a car Man TGA 35.360, the error code ZBR 01087-01 is displayed. This fault began to appear after pulling it out of the construction site with a rope excavator. I will be grateful for the info. Greetings.

Pressure Sensor No. 1 Circuit Error. It should be observant enough to reach the "red light" and lack of pressure on the dashboard .

Unfortunately. The hint was wrong in my case.
