between ABS control unit PIN 3 and sensor PIN 1 (White cable)
•
between ABS control unit PIN 12 and sensor PIN 2 (White/Brown cable)
Shorted to negative:
- Disconnect the sensor connector.
- Check the ground insulation of the two PIN.
- If there is no insulation, restore the cable harness, otherwise replace the sensor.
Shorted to positive:
- Disconnect the sensor connector.
- Check the battery supply insulation of the two PIN.
- If there is no insulation, restore the cable harness, otherwise replace the sensor.
