Troubleshooting an ABS sensor
To identify the source of any sensor faults, consider the following steps:
- Connect a diagnostic tool, record the fault codes, and check the live data parameters for the ABS sensor.
- Use a multimeter and oscilloscope to check the supply voltages and signals using – take the measurement at the sensor connector to test the entire line between the control unit and sensor.
- Inspect the connectors and wiring of the sensors to ensure they are correctly positioned and secured, and for signs of damage or contamination.
- Check the sensor and impulse ring for damage.
- If dirt is present, clean the contact surface using a wire brush
