Operating Hour Indication System Description
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 operating hours, using a combination of the tachometer needle
and "REV-LIMIT" lamp flash.
NOTE
The total operating hours displayed are those of the actual engine operation, not the ignition switch
"ON" time.
