Instrument Panel Cluster (IPC) Gauges Read Zero at Times, Gauges Inoperative at Times (Reprogram IPC)

This bulletin is being revised to change the service procedure. Please discard Corporate Bulletin Number 02-08-49-004 (Section 08 -- Body and Accessories).

Some customers may comment that at times all the IPC gauges are inoperative or read zero at times.

The IPC cluster module receives information to position the gauges when the key is turned from OFF to ON/START. Random electrical interference with this data information on the serial data line may interrupt the receipt of the information by the IPC. When the IPC data information signal is compromised, the IPC will set the gauges to zero for that complete ignition cycle. The gauges may work properly on the next ignition cycle, if the ignition was off for approximately five minutes prior to the next ignition cycle.
