System Initialization

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 antilock brake systems. The ABS 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 the dynamic test, the brake pedal is depressed, the driver may feel the test through brake pedal pulsations. This is a normal condition.

If any component sets a trouble code during system initialization or dynamic check, the CAB will illuminate the ABS warning lamp.
