| Question | Answer |
|---|---|
| This then senses any reduction in the speed of the wheels; when this occurs, a signal is sent to the modulator. | Electronic control unit |
| This receives the signal from the ECU and acts independently to control the brake pressure. Depending on the condition, this may prevent the pressure increasing, or reduce it to the corresponding wheel. | Modulator |
| These continually measure the wheel speed and, in the case of an electronic system, send this information to the ABS ECU. These use an electromagnetic sensor operating on a disc | Wheel speed sensors |
| The teeth act as a signal generator and so sense the speed of the wheel. When the wheel slows, this signals a potential wheel lock. | Reluctor/Tone wheel |
| What type of wave form does an inductive type sensor produce? | Sine wave |
| What type of wave form does a Hall effect type sensor produce? | Square wave |
| What is the correct repair procedure for an ABS sensor with an infinity resistance reading? | Replace sensor |
| Electronic brake force distribution may be used to? | Reduce braking to rear brakes in an emergency stop |
