Driver Information Center (DIC or CCDIC) Messages

CIRCUIT OPERATION

The Climate Control Driver Information Center, (DIC or 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 the BCM detects a malfunction, it stores a diagnostic code in its memory section. For certain malfunctions the BCM turns on the "SEE DRIVER INFORMATION CENTER" indicator on the information center. The DIC displays these monitored systems malfunctions in a priority order.

DIAGNOSIS

The DIC may generate messages based upon BCM or ECM inputs. When these messages are displayed, refer to BCM or ECM Input displays to diagnose these circuits.

Enter BCM or ECM input data display and observe the data display on the DIC as the circuit is being operated. The display should show the circuit switching on and off as circuit is operated. If the input display shows correct input display, but the DIC message still displays, replace the DIC.





TROUBLE CODE RELATED MESSAGES

The following messages are generated because of a BCM code being set and should be diagnosed using the appropriate code.

A/C Sensor Fault B110, B112, B113, or B115
Gear Select Problem B127
System Problem B334, B336, or B337
Batt Volts Low B411
Batt Volts High B412
Battery No Charge telltale B410
Cooling Fan Fault* B441

Low A/C Refrigerant - A/C Compressor Off B447 or B448
A/C Overheated - A/C Compressor Off B449
Engine Hot - A/C Compressor Off B450
Starting Disabled - Due to Theft System - Remove ignition key. Wait 3 Minutes, wait 2 minutes, wait 1 minute. Start Car. Theft system problem car may not restart.

*Note: Codes B441 and B450 also illuminate the "Coolant Temp/Fan" telltale.
