All test functions, with the exception of tests No's. 1 and 2, are locked after the instrument pack is reset and must be unlocked using test No. 19. This locking feature is intended to make instrument pack test functions difficult for unauthorized persons to access. Refer to Test Function No. 19 - Lock/Unlock for further details.
Once in the test function, scrolling through the tests sequentially is performed by pressing the check control button on the instrument pack. When a locked test function is encountered, pressing the trip reset button displays test No. 19 LOCK : ON to allow quick unlocking of the function.
In all markets, the text displayed in the message center for the test functions is in German only.
The instrument pack test can be exited by turning the ignition off or by holding the check control button depressed for more than 2.5 seconds.
