Brake Warning Indicator: Description and Operation
General Description
"Brake" Lamp
The "BRAKE" warning lamp in the instrument cluster warns the driver of either a loss of hydraulic fluid pressure, parking brake operation, or a
possible malfunction in the antilock brake system. The "BRAKE" lamp will illuminate when ground is supplied from either the combination valve
switch, parking brake switch, brake pressure modulator valve (4WAL).
"Antilock" Lamp
The "ANTILOCK" indicator lamp in the instrument cluster is only used on models with Four Wheel Antilock (4WAL) brakes. This lamp informs the
driver of antilock system operation and malfunctions. When a malfunction occurs, the Brake Pressure Modulator Valve (BPMV) completes the circuit
to the lamp. The lamp may remain illuminated or turn back off depending on the nature of the malfunction. The "BRAKE" lamp serves as a backup if
a malfunction occurs in this circuit.
