DESCRIPTION AND OPERATION
Instrument Cluster and Panel Illumination
The instrument cluster and panel illumination system illuminates the following components:
zinstrument cluster (10849)
z audio unit (18806)
z A/C- heater control
z fog lamp switch
z transmission range indicator
z traction control switch
z rear window defrost control switch
The instrument cluster is a hybrid electronic cluster (HEC), which uses both hardwired circuitry and the
standard corporate protocol (SCP) communication network to transmit and receive information. The
Mustang instrument cluster backlighting has illumination bulbs that are installed separately from the
instrument cluster. The Cobra instrument cluster has a laminated, electroluminescent applique to
backlight the cluster . The electroluminescent applique and instrument cluster must be installed as an
assembly. SECTION 413-

Instrument Cluster Replacement
When it is necessary to install a new instrument cluster, contact the Instrument Cluster Program.
Gauge Indication Systems
Tachometer
Engine rpm information is relayed to the instrument cluster from the powertrain control module (PCM)
over the standard corporate protocol (SCP) network.
Speedometer
The instrument cluster receives the vehicle speed signal from the PCM over the SCP network and
displays it on the speedometer gauge. If the instrument cluster receives no vehicle speed signal after
one second, the speedometer defaults to 0.0 km/h (0.0 mph).
Odometer
The instrument cluster receives an odometer message from the PCM and stores the mileage in
memory. When the instrument cluster fails to receive the odometer message for more than two
seconds, the odometer will display dashes.
Fuel Gauge
The fuel sender is hardwired to the fuel gauge. When the instrument cluster fails to receive the fuel
level signal for more than 33 seconds, the fuel level gauge will move below E (empty). If the fuel level
signal operates correctly for more than 33 seconds, the fuel gauge will return to the correct position.
Fuel fills of less than 9.5 liters (2.5 gallons) require at least 10 minutes to update the fuel gauge
indication.
Engine Coolant Temperature Gauge
Engine coolant temperature information is received by the instrument cluster from the PCM over the
SCP network. Engine coolant temperatures above 121°C (250°F) will cause the gauge to indicate
above the normal band. If the engine coolant temperature information is missing or invalid for five
seconds, the temperature gauge will indicate below the cold (C) position.
Voltage Gauge (except Cobra)
The voltage gauge displays the system voltage as measured at the instrument cluster run input. Boost Gauge (Cobra only) Klj . 2 ba
