Instrument Panel Cluster (IPC)

The IPC for this vehicle is located in the instrument panel above the steering column opening. The IPC gauges and indicators are visible through an opening in the cluster bezel and are protected by a clear plastic cluster lens that is secured to the cluster housing by integral latch formations. Several versions of the IPC are offered on this vehicle. These versions accommodate all of the variations of optional equipment and regulatory requirements for the various markets in which the vehicle is offered. The IPC utilizes integrated circuitry and information carried on the CAN data buses and CAN-Interior High Speed (IHS) along with several hard wired inputs to monitor other sensors and switches in the vehicle. In response to those inputs, the internal circuitry and programming of the IPC allow it to monitor many electronic functions and features of the vehicle. The IPC receives and manages the messages coming from the compass module and the humidity sensor (if present) via the Local Interface Network (LIN) data bus.

The IPC performs the following functions:

• Receives TPM A1 message from TPM module
• Process the information received from the TPM module
• Gives warning to the driver through a dedicated lamp, text messages and chime activation
• Manages the TPM indicator lamp function, text message and chime activation function for a loss of CAN communication

The IPC provides the following:

INPUTS

• Tire pressure indication requests from TPM
• Chime request from TPM
• TPM warning request to IPC
• TPM error request to IPC

OUTPUTS

• Odometer reading to TPM
