Supercede:
This bulletin is being revised to update the model years. Please discard Corporate Bulletin Number 07-08-49-003A (Section 08 - Body and
Accessories).
The purpose of this bulletin is to remind technicians that the engine hourmeter reading must be programmed into a new Instrument Panel Cluster
(IPC) whenever the IPC is exchanged or replaced. The Authorized Electronic Service Center will not program the engine hourmeter reading into
the new IPC unless it is provided to them. The engine hour reading is not subject to federal regulations like the odometer reading and it is not a
requirement that it be reset in the new IPC. Please make it a standard practice to record the engine hour reading, if possible, before the
original IPC is removed from the vehicle. Then provide that reading to the ESC so that it can be programmed into the new IPC. If the
engine hour reading is not readily available due to an IPC failure, then ask the customer what the engine hour reading should be set to in the new
IPC. If the engine hour reading is not provided to the ESC, the new IPC will start with an engine hourmeter reading of zero.
