Brake Warning Indicator: Description and Operation
Brake system warning light
The brake system warning light illuminates when the ignition switch is at START, the parking brake is set, or the brake fluid level is low. When
the ignition switch is at START, battery positive voltage is applied to a transistor in the instrument cluster. This transistor is turned on by applying
ground to the brake system warning light, forcing the warning light to illuminate. When the parking brake is set, the parking brake switch applies
ground directly to the brake system warning light. When the brake fluid level is low, the brake fluid level sensor closes and applies ground directly
to the brake system warning light, causing the brake system warning light to illuminate.
