Circuit Operation
The brake system warning lamp goes on to alert the
driver that the parking brake is applied or that the brake
fluid is low. It also lights as a bulb test when the engine is
cranked.
Parking Brake Switch
With the starter switch in ON or START, battery voltage
is applied through the C-11 METER fuse to the brake
system warning lamp. When the parking brake is ap-
plied, the parking brake switch closes and provides a
ground for the lamp. The brake system warning lamp
goes on to remind the driver that the parking brake is
applied.
Brake Fluid Level Switch
With the starter switch in ON or START, battery voltage
is applied through the C-11 METER fuse to the brake
system warning lamp. If the brake fluid is low, the brake
fluid level switch closes and provides a ground for the
lamp. The brake system warning lamp goes on to warn
the driver of low brake fluid level in the brake master cyl-
inder. (Note: check brake pad wear before adding fluid.)
Bulb Check
With the starter switch in START, the brake system
warning lamp is turned on for bulb check. During bulb
check, the lamp is grounded through the alternator. See
Indicators for further details.
