Ford Fiesta: Instrumentation, Message Center and Warning Chimes / Instrument Panel Cluster (IPC) - Overview. Description and Operation

Overview

The IPC contains gauges, informational indicators, warning indicators and an integrated LCD designed to provide the driver with system status and to alert the driver when certain conditions exist in the vehicle.

Gauges

Gauges inform the driver of the status of systems. The systems that use gauges are as follows:

• Engine rpm
• Fuel level
• Vehicle speed

Informational and Warning Indicators

Informational indicators provide information to the driver of conditions that exist in the vehicle. Warning indicators provide information to the driver of conditions that could potentially cause personal injury or alter vehicle performance.

All informational and warning indicators are Light Emitting Diodes (LEDs) and are not replaced separate from the IPC .

IPC Integrated LCD

The IPC integrated LCD , located in the top center of the IPC , uses a 3-line LCD . The IPC integrated LCD is controlled by the trip computer switch, located on the multifunction switch. The IPC integrated LCD provides the following information:

• Odometer
• Trip odometer
  • DTE
  • average fuel economy
  • average speed
  • instantaneous fuel economy
  • outside air temperature
• Engine temperature gauge
• PRNDL (automatic transmission only)

Network Messaged Inputs

Module messaging has increased over time and has become the standard for sending and receiving information required to operate the IPC . The majority of the inputs required to operate the IPC are received over the CAN .

Hardwired Inputs

The IPC requires hardwired inputs from components that are not on the CAN . These components are required for specific IPC functions.

The hardwired inputs are provided by the following components:

• Fuel sender
• Clutch switch
• Parking brake position switch
• A/C switch (vehicles equipped with EMTC )
• Accelerator pedal
• Brake fluid level switch
• Ambient Air Temperature (AAT) sensor
• Park detect switch (part of the floor shifter assembly, vehicles equipped with automatic transmission)
• Cruise control switches
• Brake pedal switch
