Antilock Brake System (ABS) Module

The Antilock Brake System (ABS) control module controls the ABS telltale indicator lamp, TRACTION ACTIVE telltale, and is one of three inputs that control the BRAKE telltale indicator lamp.

The ABS control module controls the ABS telltale lamp indicator through telltale control logic in the instrument cluster. When the ABS control module grounds the input of the cluster, the telltale control logic is Off and the ABS telltale indicator lamp is Off. If the ABS control module ungrounds the circuit, or the circuit becomes open and ignition voltage is present at the cluster, the telltale control logic turns On and the ABS telltale indicator comes On. The ABS control module turns On the ABS telltale indicator lamp if it senses a possible problem in the electronics of the antilock brake system.

The BRAKE telltale indicator is turned On if the ABS control module senses a possible problem in the mechanical function of the brake system.
