Circuit/System Testing

  1. Ignition OFF, disconnect the yaw rate and lateral acceleration sensor connector.
  2. Ignition OFF, test for less than 1 Ω between the low reference circuit terminal 6 and ground.
    • If greater than 1 Ω, test the low reference circuit terminal 6 and the EBCM ground circuit terminal 25 (JL4) terminal 45 (without JL4) for an open/high resistance. If the circuits test normal, replace the EBCM.
  3. Test the lateral accelerometer 12 V reference circuit terminal 1, for an open/high resistance or a short to voltage or ground.
    • If all circuits test normal, replace the yaw rate sensor/lateral acceleration sensor, and clear the yaw rate sensor offset value in the EBCM.
    • If the DTC sets again after replacing the yaw rate sensor/lateral acceleration sensor, replace the EBCM.
