L322 Range Rover System Description and Operation
DESCRIPTION AND OPERATION
There are 21 test and reset functions available as shown in the following table:
Pressing the check control button moves the display to the next function in the sequence. When a selected function
is reached, pressing the trip reset button enters the test function details.
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
unauthorised persons to access. Refer to function test No. 19 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 centre 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.
