System initialization starts when the key is turned to "run". At this point, the Controller Antilock Brake (CAB) performs a complete self-check of all electrical components in the antilock systems.

Between 8-17 km/h (5-10 mph), a dynamic test is performed. This will momentarily cycle the inlet and outlet valves and run the pump/motor at 25 km/h (15 mph), the CAB will try to test the pump/motor. If the driver has their foot on the pedal the test will be run at 40 km/h (24 mph) regardless of brake switch state. If, during the dynamic test, the driver has his/her foot on the brake pedal, he/she may feel the test through brake pedal pulsations. This is a normal condition.

If any component exhibits a trouble condition during system initialization or dynamic check, the CAB will send a command to illuminate the ABS warning lamp and TRAC OFF lamp if equipped.
