PB1318 3/01 Model 330
Power Steering Flow Switch: senses flow of power steering
fluid.
Power Steering Fluid Reservoir: stores power steering fluid
and offers a place to replenish when needed.
Power Steering Gear: assists the steering operation and
sends pressurized power steering fluid to the brake booster.
Power Steering Pump: draws power steering fluid from the
reservoir and sends it to the power steering gear.
Warning Buzzer: sounds when either power steering fluid
flow is interrupted or when a pressure differential is present
between the primary and secondary brake fluid pressure.
Either case adversely affects braking operation.
Brake Warning Lamp
When the brake warning lamp comes on, it indicates a mal-
function in the brake system. Possible malfunctions include
loss of hydraulic pressure from the power steering circuit or a
pressure differential between the primary and secondary
brake circuits.
WARNING! Do not operate the vehicle if the
brake light or buzzer comes on. The light or
buzzer indicates a failure in one of the brake
components/system. Drive your vehicle to the
side of the road immediately. Failure to do this
may lead to an accident and severe injury.
If the buzzer sounds while driving, or if the BRAKE light
comes on, do the following:
