There are several possible causes of the problem with the adaptation of the box of the Isitronics box to the Opel Vektra C:
-Burgings of gearshifts. Usually accompanied by error P1732. In this case, it is necessary to replace wornout parts.
-Air supply in the clutch actuating system. To resolve, you need to pump the system.
-The clutch of the clutch was not properly installed after repair (to the extreme position).
-The main brake cylinder is clogged.
-I lost contact between the box and the cooking. The error is accompanied by error P1722. The problem is fixed by the search for a burning wire or purchase of a new joystick.
-The power line is over. Error R1607 appears. To fix it, we're trying to move the mashup manually.
