Diagnostic test allows you to make sure that headlights, power windows, door locks and other components respond to commands correctly. This is especially useful when purchasing a used car or after an electronics repair.
Entering this mode often requires the use of specialized equipment or a combination of steering wheel and dashboard buttons. Without the correct access, you will not be able to run verification procedures. Control units at this moment they go into self-monitoring mode, ignoring some signals from the sensors in order to check the reaction of the drives.
How to activate the service through the diagnostic interface
The most reliable way to enter the inspection service is to use a professional diagnostic scanner or laptop with installed software VCDS (VAG-COM) or ODIS. Simply press buttons on the instrument panel Octavia A7 may not work or result in an accidental reset.
The activation procedure is as follows: connect the adapter to the OBD-II connector located under the instrument panel. Launch the diagnostic program and select your vehicle. In the control unit menu, find the section responsible for service functions. Usually this is a block 09-Center electr. or 17-Device.
To run the test you must select the function 04-Basic settings or 10-Adaptation. Enter codes that correspond to specific tests. For example, code 12345 can run a light test. It is important to pay close attention to messages on your computer screen so you don't miss any error codes.
If you are using a mobile app via Bluetooth, make sure it supports full feature access inspection service. Some simplified versions of programs have limited functionality and do not allow deep tests.

Basic Inspection and Testing Procedures
After successfully entering the mode, a series of automated checks begins. The system may require you to manually confirm actions, such as pressing the brake pedal or turning the steering wheel. This is necessary to check the operation of position sensors and actuators.
Particular attention is paid to checking lighting devices. Inspection service alternately turns on the low and high beams, dimensions, turn signals and brake lights. You need to get out of the car and make sure that all the lights come on and off in the correct sequence. If any lamp does not work, the system will display an error code.
Testing of power windows and central locking is also carried out. Doors should open and close, and windows should go up and down without delay. This test checks the operation of motors and limit switches. If the mechanism jams, this will be recorded in the error memory.
Don't forget to check the operation of the climate control and multimedia system. In this mode, you can check the response of fans, dampers and audio systems to commands. This helps identify problems with wiring or the control units themselves before they lead to complete failure.
☑️ System check checklist
