Ford Mustang (1999-2004) Service Manual: 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
