Brake Lamp
The brake warning lamp in the instrument cluster warns the driver of
the following conditions:
| • | A loss of hydraulic fluid pressure |
| • | Parking brake operation |
| • | A possible malfunction in the antilock brake system |
The brake lamp illuminates when one of the following switches or valves
supplies ground:
| • | The combination valve switch |
| • | The parking brake switch |
| • | The brake pressure modulator valve |
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
stay 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. Refer to
Antilock Lamp, in Four Wheel Antilock Brake System.
