System Initialization

System initialization starts when the key is turned to "RUN". At this point, the CAB performs a complete self-check of all electrical components in the anti-lock brake system.

At 20 km/h (12 mph) a dynamic test may be performed. If the brake lamp switch is activated, the test will be run at 40 km/h (24 mph) regardless of the brake lamp switch state. This will momentarily run the pump/motor. 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 causes a diagnostic trouble code during system initialization or dynamic check, the CAB will illuminate the ABS warning indicator.
