Alarms

When the system is turned ON, the warning indicator will flash as the system powers up.

If YELLOW warning indicator is displayed, the system is operable, but the warning should be investigated as soon as possible.

If RED warning indicator comes ON during operation, the system will shut itself OFF. The system should be checked immediately, as this could indicate a major failure.

Note Alarm codes can only be cleared using a laptop PC equipped with CANDiag. software. Log alarms should only be cleared after scheduled service has been completed.
