Driver Information Center (DIC) Description and Operation (CTS-V only): Notes

The instrument panel cluster (IPC) is equipped with 2 message centers that convey additional vehicle information to the driver. The vehicle information displayed by the message centers relate to vehicle performance, odometer and transmission range information. Certain IPC indicators illuminate in conjunction with a vehicle information displayed in the message center. The IPC coordinates the illumination of the indicator with the display of the driver warning message in the message center. There are 4 steering wheel mounted switches that are read by the cluster. Three of the switches are used to control and manage the right hand (RH) and left hand (LH) message centers. The fourth switch is the Traction On/Off switch. All 4 switches are read from a single input to the IPC. The switches are setup in a resistor ladder format where each switch press provides a unique voltage range read by the IPC.

Driver Information Center (DIC) Switches:

• RH INFO Switch (controls right-hand DIC)
• LH INFO UP Switch (controls left-hand DIC)
• LH INFO DOWN Switch (controls left-hand DIC)
• Traction On/Off Switch
