Instrument Panel Cluster (IPC) Description and Operation: Notes

The powertrain control module (PCM) sends serial data to the body control module (BCM) along the primary serial data bus circuit. Serial data is then sent to the instrument cluster along the secondary serial data bus circuit. The following data is read by the instrument cluster, which then indicates the status as appropriate on the multifunction display (MFD) and/or cluster warning indicators:

• Oil pressure
• High temperature
• Check engine (powertrain)

A powertrain interface module (PIM) is required to convert the serial data generated by the (PCM) into serial data that is compatible with the BCM.
