  1. Verify that DTC C0710 is not set.
  2. Ignition OFF, disconnect the harness connector at the yaw rate/lat sensor.
  3. Ignition OFF for 60 seconds, test for less than 5 ohms between the low reference circuit terminal 1 and ground.
    • If greater than the specified range, test the low reference circuit for an open/high resistance.
  4. Ignition ON, test for B+ between the ignition voltage circuit terminal 4 and ground.
    • If not within the specified range, test the ignition voltage circuit for a short to ground or open/high resistance.
  5. If all circuits test normal, replace the yaw rate/lat sensor.
