Circuit/System Testing

WARNING: This page is about a different car, the 2008 Buick Lucerne. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: It is recommended that Component Testing  is performed before Circuit Testing when diagnosing wheel speed sensors.
  1. With the ignition OFF, disconnect the EBCM connector.
  2. With the ignition ON, measure for 0 volt between the sensor signal circuit terminal or the low reference circuit and ground at the EBCM connector.
    • If over 0 volt, repair short to voltage in sensor signal circuit or the low reference circuit.
  3. With the ignition OFF, measure for infinite ohms of resistance between the wheel speed sensor signal or the low reference circuit and ground at the EBCM connector.
    • If less than infinite ohms, repair short to ground in the sensor signal or the low reference circuit.
  4. Measure for 850-1350 ohms of resistance between the wheel speed sensor signal and low reference circuits at the EBCM connector.
    • If greater than 1350 ohms test for an open/high resistance in the circuit or faulty wheel speed sensor.
    • If less than 850 ohms test for a short between the circuits or faulty wheel speed sensor.
  5. If all circuits test normal replace the EBCM.
