When the ignition switch is turned on, the ICU per-
forms a self-test, looking for active faults. During the
first half of the self-test, all segments of the display
illuminate as follows:
•
First line (odometer): 888888.8
•
Second line (units): TRIP MI KM HOURS
•
Third line (voltmeter): 38.8 VOLTS
•
Fourth line: SERVICE ENGINE
During the second half of the self-test, the software
revision level is displayed.
If there are no active faults, the driver display screen
displays the odometer.
If however, the instrument cluster has received active
fault codes from other devices, it displays them one
after the other until the parking brake is released, or
the ignition switch is turned off. Once the parking
brake is released, the dash message center displays
the odometer again.
