Controller Antilock Brake: Description

The controller antilock brake (CAB) is a microprocessor-based device which monitors the ABS system during normal braking and controls it when the vehicle is in an ABS stop. The CAB uses a 24-way electrical connector on the vehicle wiring harness. The power source for the CAB is through the ignition switch in the RUN or ON position. The CAB is on the PCI bus.

The CAB is mounted to the HCU as part of the Integrated Control Unit (ICU). Attached to the bottom of the HCU, it can be viewed from below, just above the transaxle and left halfshaft (Fig. 2). For information on the ICU, see DISC & DRUM article.
