help in troubleshooting without the diagnostic tester.

The test functions are only shown in the instrument-cluster LC display.

The test functions are activated by pressing the left setting button in the instrument cluster

(S/R, 5 seconds) with terminal R or terminal 15 ON. In addition, the test functions can still

be called up by pressing the left setting button (S/R for Set/Reset) in the instrument cluster

with simultaneous activation of terminal R.

The test functions are shown in the odometer and trip-odometer display areas in the top

line of the display.

The display of the on-board computer function is retained in the bottom display line.

Test function 19

Only the first two test functions are freely accessible. All further test functions are locked

from the third test function. The lock can only be removed by means of test function 19.
