Instrument Cluster System Test

Instrument Cluster System Test

Test functions
The test functions serve to check the coding and to run troubleshooting without the diagnosis tester. The test functions are displayed in the top line of the LC display, display area 1 (distance recorder). The display of the on-board computer function in the bottom line is retained.

NOTE: The test functions can only be run with terminal R On and terminal 15 On with the vehicle stationary and the engine switched off.

The test functions are switched on by
- pressing the S/R button for a longer period (> 5 seconds) with terminal R On and/or terminal 15 On or by
- pressing the S/R button and simultaneously switching on terminal R.

Test functions 1 and 2 are freely accessible. The following test functions can only be reached after they have been unlocked using test function 19. In test function 19, the display alternates every second between L_on (Lock on = lock) and L_oFF (Lock off = unlock).

To unlock the test function:
Press the S/R button if the display shows L_oFF (Lock off = unlock). The display jumps to test function 0 (Exit test function).

To lock the test function:
Press the S/R button if the display shows L_on. Otherwise, always lock the test functions using test function 19.

NOTE: The test functions are always locked after a terminal change.

Quit test functions:
The test functions are closed
- by switching from terminal R Off or
- pressing the S/R button for a longer period or
- requesting test function 21.
