Driver/Vehicle Information Display: Description and Operation

The Driver Information Center (DIC) consists of various indicators as well as switches that control the fuel and trip data information. An Ambient Light Sensor is also located within the DIC to control Instrument Cluster dimming.

Power for the DIC is supplied by the Cluster Fuse when the Ignition Switch is in "RUN," "BULB TEST" or "START". The voltage applied is used for the indicators. Power for the switches is supplied by the Central Control Module (CCM).

A description of the various DIC components is given starting below.

"LOW TIRE PRESSURE" Indicator

See "Low Tire Pressure Warning System".

"SERVICE LTPWS"

See "Low Tire Pressure Warning System".

"CHECK CHARGING SYSTEM" Indicator

See "Starter And Charging System".

"SERVICE RIDE CONTROL" Indicator

See "Ride Control".

"LOW COOLANT" Indicator

The Low Coolant Switch will illuminate the "LOW COOLANT" Indicator by grounding one side of the bulb when a low coolant condition exists.

"LOW OIL LEVEL" Indicator

When a low oil level is detected, the Low Oil Level Sensor will remove the ground to the Central Control Module (CCM). The CCM will in turn ground one side of the "LOW OIL LEVEL" Indicator, illuminating it.

The CCM may wait several hours before turning on the indicator to insure that the oil has drained back into the oil pan and that a low oil condition actually exists.

"PASSIVE KEYLESS ENTRY" Indicator

See Body Electrical section.

"INFL REST" Indicator

See Supplemental Restraints section.

"ABS ACTIVE" Indicator

See Brakes section.

"ASR ACTIVE" Indicator

See Brakes section

"ASR OFF" Indicator

See Brakes section.

"SERVICE ABS" Indicator

See Brakes section.

"SERVICE ASR" Indicator

See Brakes section.

"SERVICE ENGINE SOON" Indicator

See Powertrain Management section.

Driver Information Switches

The Central Control Module (CCM) will detect the switch closures for the Fuel and Trip Data and the English/Metric Switches. The CCM will process this information and display the information on the Instrument Cluster Digital (LCD) display.

The CCM will set a code if a problem occurs with wires between the DIC and CCM.

Important: Anytime the Driver Information Center (DIC) connector is disconnected and the Ignition Switch is "ON," an SIR Code 61 will be set.
