6. Drive the vehicle at speeds above 40 km/h (25 mph) for 10 minutes.
7. The counters will increase by one each time a sensor signal is received by the EVIC (approximately 1/min from each wheel except the spare).

Vehicle Communications
VEHICLE COMMUNICATION
The Programmable Communication Interface or PCI Bus is a single wire multiplexed network capable of supporting binary encoded messages shared
between multiple modules. The PCI bus circuit is identified as D25. The modules are wired in parallel. Connections are made through the BCM. The
BCM acts as a splice to connect each module and the Data Link Connector (DLC) together. Tile following modules are used on 2003 LH:
-
Airbag Control Module
-
Left Side Impact Airbag Control Module
-
Right Side Impact Airbag Control Module
-
Controller Antilock Brake
-
Powertrain Control Module - Next Generation Controller (NGC)
-
Radio (If equipped)
-
CD Changer (If equipped)
-
Overhead Travel Information System (If equipped)
-
Memory Heated Seat and Memory Mirror (If equipped)
-
Automatic Temperature Control (If equipped)
-
Body Control Module
-
Sentry Key Immobilizer Module (If equipped)
-
Mechanical Instrument Cluster
Each module provides its own bias and termination in order to transmit and receive messages. The bus voltage is at zero volts when no modules are
transmitting and is pulled up to about 7 1/2 volts when modules are transmitting.
