Instrument Cluster Test Functions

In addition to the fault memory and diagnostic link, the base instrument cluster contains a series of test functions that can be accessed to check various functions and values. The test functions are displayed in the mileage LCD block. There are a total of 21 test functions.

The test functions are similar to those of previous Board computers and contain similar tests.

• Tests 1 & 2 are always unlocked.
• Tests 3 -21 are only accessible after unlocking the test function. Test 19 is the unlock function for accessing the displays.

Scrolling through the numbered test functions is achieved by pressing the instrument cluster button.

The button is either momentarily pressed (tapped) < 1 second or pressed and held for > 1 second.

This signals the BC to display the sub-tests of the displayed main test menu or continue on to the next main test menu.
