ABS Light: Description and Operation

Antilock Lamp

Models with four wheel antilock brakes use the antilock indicator lamp in the instrument cluster. The lamp informs the driver of antilock system operation and malfunctions. When a malfunction occurs, the brake pressure modulator valve completes the circuit to the lamp. The lamp may remain on or turn off depending on the nature of the malfunction. The brake lamp serves as a backup if a malfunction occurs in this circuit.
