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 systems. The ABS, TRAC OFF, TRAC and brake warning lamps will illuminate for 4 seconds with ignition on.

At 20 km/h (12 mph), a dynamic test is performed. This will momentarily run the pump/motor. If during 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 diagnostic trouble code during system initialization or dynamic check, the CAB will illuminate the ABS warning indicator and TRAC off warning indicator.
