Control System (Check Control) (Opel Astra H)

The control system monitors the main operating parameters that determine the safety of the vehicle. Depending on the configuration, the levels of liquids, air pressure in the tires, the state of the power supply element of the remote control device, the serviceability of the anti-theft alarm device, as well as the serviceability of the most important external lighting lamps, including wiring and fuses, are checked.

Note: When using with a trailer, the external lighting of the trailer is also monitored.

If a malfunction is detected in any of the systems, a corresponding warning message appears in the display field. If there are several warning messages, they are displayed one after the other.

Note: Some warning messages are displayed using abbreviations.

When a message is displayed on the screen, you must confirm its receipt as described above.
