Instrument Cluster Test Functions
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.

Sub-Tests
L-ON...
L-OFF 19.0 =
Display changes from "L-ON" to "L-OFF" every second. To unlock test functions, press the cluster button immediately when it changes to "L-OFF".
Tests are automatically locked when exiting test functions
TEST 20. - Average fuel consumption - correction factor
The factor follows previous systems, with adjustment range of 750 to 1250. The adjustment method is new for the base cluster. If adjustment is necessary, enter into test 20 using the cluster button.
The correction factor number is changed by using the sub-tests for the "ones, tens and hundreds of the factor number. The digits will automatically scroll through 0-9 within each group (ones, tens, hundreds).
Sub-Tests:
XXX9 20.0 =Press the button when the correct "ones" position is attained.
XX5X 20.1 =Press the button when the correct "tens" position is attained.
12XX 20.2 =Press the button when the correct "hundreds" position is attained.
TEST 21. - Software reset
Sub-Test:
reset 21.0 =Reset software
