Instrument Panel Cluster (IPC) Description and Operation: Hourmeter

The IPC can display the accumulated engine run time hours using the VF display when the ignition is in the LOCK or ACC position. The IPC stores the accumulated engine run time hours in a non-volatile format. The accumulated hours would not change if the battery was disconnected or removed. When the ignition is in the LOCK, ACC or OFF positions and the trip reset switch is pushed in and held for more than 4 seconds, the IPC will display the accumulated hours for 30 seconds. The hourmeter will reset to 0.0 when 10,000 hours are accumulated, and begin to accumulate hours again.
