ROUTINE OPERATION
Antilock Braking System (ABS)
In a vehicle equipped with an antilock braking system (ABS), motion sensors detect
the speeds at which the wheels move. These sensors transmit this information to an
Electronic Control Unit (ECU). If the wheels start to lock, the ECU signals the modula-
tor assembly to regulate the brake pressure of each wheel.
An ABS indicator lamp on the dash (see “Indicator Light Panel” in Instrument
Panel section) warns the driver of possible system faults and provides blink code
information to diagnose the system. If this light is activated during normal vehicle
operation, the driver may complete the trip, but the vehicle must be serviced as
quickly as possible.
