DESCRIPTION AND OPERATION (Continued)
There are two switches used in this system and
they are wired in parallel form. A parking brake
switch located on the parking brake mechanism will
illuminate the lamp if the normally OPEN switch is
CLOSED. This switch is case grounded.
The other switch used is the brake warning lamp
switch. This switch is normally OPEN. When the
brake system pressure is below a predetermined level
the switch CLOSES and completes a path to ground
from the G9 circuit at the cluster, through the
switch, to the left headlamp ground.
ANTI-LOCK WARNING LAMP
The Anti-Lock warning lamp is used to alert the
driver of a problem in the ABS system. When the
ABS controller determines a problem in the system it
grounds the G19 circuit and illuminates the lamp.
