MID Function Tests: Notes

The MID offers an integrated function test for workshop testing purposes. The test menu is called up by simultaneously pressing the first and the last menu button while switching on the ignition. This menu is generated by the MID itself, and the tests are carried out by the MID. The display is disabled for the testing period, even in the event of a display request. The test is also possible without the I/K BUS connected.

The following are offered in the test menu (selection carried out via the MID rocker buttons):

• DISPLAY: Display test
• KEYS: Button functions
• VOLUME: Increment sensor test
• LEDS: for LED function displays.

The test is concluded by switching the ignition off or after a time out of 5 seconds has elapsed after the last button actuation.
