Brake Warning Indicator: Description and Operation
The brake system indicator light comes ON to alert the driver that the parking brake is applied, or that the brake fluid level is low. It also comes on as a
bulb test when the engine is cranked.
Parking Brake
With the ignition switch in ON (II) or START (III), voltage is applied through fuse 1 to the brake system indicator light. When you apply the
parking brake, the switch closes and provides a ground for the light, and the light comes ON to remind the driver that the parking brake is applied.
Brake Fluid Level
With the ignition switch in ON (II) or START (III), voltage is applied through fuse 1 to the brake system indicator light. If the brake fluid level is
low, the brake fluid level switch closes, providing ground to the circuit. The brake system indicator light then comes ON, alerting the driver to a
low brake fluid level in the master cylinder. (Check brake pad wear before adding fluid.)
Bulb Check
With the ignition switch in START (III), voltage is applied through fuse 9 to the bulb check circuit. The bulb check circuit closes, allowing current
to flow through the brake indicator system indicator light and bulb check circuit to ground. The brake system indicator light then comes ON to test
the bulb.
