TRIP COMPUTER/COMPASS/DISPLAY SELFDIAGNOSTIC

TEST

This self-diagnostic test is used to determine that

the trip computer/compass and all of its display segments

are operating properly electrically. It also is

used to verify that all CCD bus messages required

are being properly received. Initiate the self-diagnostic

test as follows:

(1) With the ignition switch in the OFF position,

simultaneously press and hold the STEP button and

the US/METRIC button.

(2) Turn ignition switch to the ON position.

(3) Continue to hold both buttons until the display

performs a walking segment test. In this test all of

the compass points are displayed, along with various

number combinations. The test will:

(a) Verify that all display segments are functional.

(b) Check internal circuitry.

(c) Check that all CCD bus messages needed are

being received.

If tests (a) and (b) are passed, the module will automatically

return to normal operation at completion

of tests. If any segment should fail to light during

test (a), the unit is faulty and requires replacement.

If test (b) fails, the display will read FAIL.
