Ford Mustang Service Manual: Pinpoint Tests
Principles of Operation
NOTE: A new instrument cluster must be reconfigured. Refer to Section.
The instrument cluster is a hybrid electronic cluster (HEC). The instrument cluster uses both hardwired and the standard corporate protocol (SCP) communication network to transmit and receive information. As a technician it is very important to understand:
- where the input originates from.
- all 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 SCP network to another module?
- which module controls the output of the feature.
The instrument cluster carries out a display prove-out to verify that the warning/indicator miniature bulbs for monitored systems are functioning correctly. When the ignition switch is in the ON position with the engine off, the following warning indicators will prove out:
- anti-lock brake (ABS) warning indicator
- air bag warning indicator
- BRAKE warning indicator
- charging system indicator
- fail safe cooling warning indicator
- low coolant level indicator
- low fuel warning indicator
- traction control indicator
