Principles of Operation: Notes
WARNING: This page is about a different car, the 2013 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
When installing a new Instrument Panel Cluster (IPC), it is necessary to upload the module configuration to the scan tool. Following installation of the IPC, download the module configuration from the scan tool into the new IPC. Refer to
MODULE CONFIGURATION
to carry out Programmable Module Installation (PMI). It is also necessary to carry out a parameter reset procedure whenever a new IPC or PCM is installed. Refer to
ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS)
.
The IPC, message center and warning chimes utilize a microprocessor to control the gauge and indicator functions. Data is sent to the IPC over the Medium Speed Controller Area Network (MS-CAN) and the High Speed Controller Area Network (HS-CAN) bus lines and through hardwired circuitry from individual components. The IPC uses each input to output an action to the gauges or indicators.
It is very important to understand:
- where the input originates.
- all the information necessary in order for a feature to operate.
- which module(s) receive(s) the input or command message.
- does the module which received the input control the output of the feature, or does it output a message over the communication network to another module.
- which module controls the output of the feature.
