Engine General Information and Diagnosis: 1A-13
Operating Hour Indication System Description
Z9J0111101006
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.
