Brake Warning Indicator: Description and Operation
Circuit Description
The brake warning indicator light goes on to alert the driver that the parking brake is applied or that the brake fluid level is low. It also lights as a bulb
test when the engine is cranked. With the ignition switch in ON or START, battery voltage is applied from fuse 19 to the brake warning indicator.
Parking Brake
When the parking brake is applied, the switch closes and provides a ground for the light. The brake warning indicator goes on to remind the driver that
the parking brake is applied.
Brake Fluid Level
If the brake fluid level is low, the brake fluid level switch closes and a ground is provided to the circuit. The brake warning indicator warns the driver of
low brake fluid level in the brake master cylinder.
Bulb Check
The generator will provide a ground to the circuit until the engine is running. The brake warning indicator goes on to test the brake warning light bulb
and then goes off.
