System Overview
The climate control system provides filtered air to
the cabin from a fully automatic, dual zone,
temperature controlled system. Driver and front
passenger have independent control of the
temperature of the air for their individual
comfort. The system regulates the volume of
airflow from the vents of the instrument panel,
rear seat panel, front and rear floor ducts, front
screen defroster and side windows. It will
automatically select between fresh and
recirculated air to assist rapid cooling of the
interior.
Operation of the heated front screen or heated
wiper park area and rear window heater is
controlled from the climate control panel. Door
mirror heaters are automatically switched on
when the heated rear window is switched on. As
with current vehicles, the outside air temperature
can be displayed in either Celsius or Fahrenheit.
The system can be switched ON by pressing any
button, except OFF.
When ÔAUTOÕ is selected, the driverÕs and front
passengerÕs air temperature, fan speed and air
distribution are automatically controlled to give

PCM Flash Programming Link
Serial Data Link The multiplexed electrical architecture is used for
the exchange of information between control
modules, the instrument pack and the data link
connector.
Multiplexing allows more than one piece of
information to be carried along a wire. In this
way, the electronic control modules can
communicate with each other quickly and share
information. With multiplexing, just two
intertwined wires carry information to any control
module on the network. On the SCP system
hundreds of messages a second can be
transmitted; the maximum waiting time is only a
few hundred milliseconds. An additional benefit is
that the modules ÔsleepÕ when not in use,
reducing battery drain.Principles of Operation
The vehicle has two module communication
networks. The first is the Standard Corporate
Protocol (SCP - J1850 SAE standard)), which is an
unshielded twisted pair cable: data bus plus and
data bus minus. The second is the International
Standard Organization (ISO) 9141 communication
network, which is a single wire network. Both
networks can be connected to the PDU tester by
one connector: the data link connector. The data
link connector is located under the instrument
panel, between the steering column and the audio
unit.
The ISO 9141 communications network does not
permit inter-module communications. When the
PDU tester communicates to modules on the ISO
9141 communication network , the PDU must ask
for all information; the modules initiate
communications.
