Circuit/System Description

WARNING: This page is about a different car, the 2007 Pontiac G5 Pursuit, 2007 Pontiac G5, and 2007 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.

The driver information center (DIC) switch is a normally open momentary switch. Battery power is provided to the DIC switch via the instrument panel cluster (IPC) with the DIC switch signal circuit pulled up to battery voltage in the IPC. The battery positive voltage circuit is fused in the body control module (BCM). The instrument panel cluster (IPC) interfaces with the driver information center (DIC) switch via two discreet circuits. The switch input to the cluster is pulled low or grounded when a switch is activated. The IPC reads the voltage at the analog input to determine which switch input is pressed. The switch input to the cluster is set up in a resistor ladder format. The DIC switch includes the INFO and the SET/RESET switch. A simultaneous press and hold of the INFO and SET/RESET switch activates the MENU switch. The MENU switch is the third embedded switch used to activate the various DIC personalization menu.
