Allante V8-273 4.5L (1991)
Driver/Vehicle Information Display: Description and Operation
The Climate Control Driver Information Center (CCDIC) displays diagnostic information, fuel information, engine data, temperature, time and
monitored systems messages. It communicates with the Body Computer Module (BCM) over the Data line.
When using the diagnostic system, the CCDIC displays all PCM, BCM, and IPC Inputs. It will also display all PCM, and BCM outputs, and data results
along with Override Outputs.
The CCDIC displays fuel related information through the Data Line from the BCM. The BCM receives information from the Fuel Gage Sender and the
Powertrain Control Module (PCM). It calculates range and gasoline consumption values and transmits them to the CCDIC when the appropriate
CCDIC button is pushed.
The outside temperature and the date and time are displayed when the TEMP TIME button is pressed and the Ignition Switch is in RUN. The BCM
continuously looks at its inputs and feedback signals to check that the operating conditions are acceptable. When the BCM detects a malfunction, it
stores a diagnostic code in its memory section. For certain malfunctions, the BCM turns on the CHECK INFO CENTER Indicator on the Instrument
Panel. The CCDIC displays these monitored systems malfunctions in a priority order.
