Normal Operation
The ABS module uses input from the brake pedal angle sensor to determine the amount of deceleration the driver is requesting. The brake pedal angle sensor utilizes 2 Hall-effect sensors that provide redundant signals indicating the position of the brake pedal. The ABS module provides a 5-volt reverence voltage used by both of the sensors. The ABS module provides a signal return common to both sensors.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Brake pedal angle sensor
- ABS module
