Operating Hour Indication System - Suzuki DF 90 Service Manual

OPERATING HOUR INDICATION SYSTEM

When the ignition switch is initially turned "ON" (from "OFF"),
the ECM tests the caution system by turning on all four lamps
in the monitor-tachometer and sounding the caution buzzer for
an initial two seconds.
For the next three seconds, the ECM indicates the total operat-
ing hours, using a combination of the tachometer needle and
"REV-LIMIT" lamp flashing.
NOTE:
The total operating hours displayed are those of actual engine
operation, not ignition switch "ON" time.
