Circuit/System Testing

WARNING: This page is about a different car, the 2008 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

C0196 00

  1. Visually inspect the yaw rate sensor/lateral accelerometer for proper and secure mounting.
    • If the sensor is improperly secured, remove and properly install the sensor.
  2. Ignition OFF for 30 seconds, disconnect the harness connector at the yaw rate sensor/lateral accelerometer.
  3. Ignition OFF for 30 seconds, test for less than 15 ohms between the low reference circuit terminal 6 and ground.
    • If greater than the specified value, remove the EBCM connector and test for less than the specified value between the low reference terminal 22 and ground terminal 16 of the EBCM.
    • If EBCM measures less than the specified value, test the yaw rate sensor low reference return circuit terminal 6 and the EBCM connector ground circuits terminal 16 and 45 for a short to voltage or an open/high resistance. If the EBCM measures greater than the specified value, test or replace the EBCM.
  4. Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal 1 and ground.
    • If greater than the specified range, test the 5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the EBCM.
    • If less than the specified range, test the 5-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM.
  5. Ignition OFF, disconnect the harness connector at the EBCM.
  6. Ignition ON, test for less than 1 volt between the following signal circuits and ground:
    • Yaw rate signal terminal 3
    • Lateral accelerometer signal terminal 2
    • If greater than the specified range, test the signal circuit for a short to voltage.
  7. Test for less than infinite resistance between the following signal circuits and ground:
    • Yaw rate signal terminal 3
    • Lateral accelerometer signal terminal 2
    • If not the specified value, test the signal circuit for a short to ground.
  8. Test for less than 2 ohms between the following signal circuit terminals:
    • Terminal 3 at the sensor harness connector and terminal 37 at the EBCM harness connector
    • Terminal 2 at the sensor harness connector and terminal 8 at the EBCM harness connector
    • If greater than the specified range, test the signal circuit for an open/high resistance.
  9. If all circuits test normal, test or replace the yaw rate sensor/lateral accelerometer. After replacement and programming, operate the vehicle within the conditions for running the DTC and verify DTC C0196 00 does not set.
    • If the DTC sets, replace the EBCM.

C0196 28

  1. Verify DTC C0196 00 is not set.
    • If DTC C0196 00 is set, refer to the above diagnostic procedure for C0196 00 before proceeding.
  2. Ignition OFF, disconnect the harness connector at the yaw rate sensor/lateral accelerometer.
  3. Test for 118k ohms between the yaw rate diagnostic signal circuit terminal 4 and ground.
    • If greater than the specified value, test the signal circuit for an open/high resistance. If the circuit tests normal, replace the EBCM.
    • If less than the specified value, test the signal circuit for short to ground. If the circuit tests normal, replace the EBCM.
  4. If all circuits test normal, test or replace the yaw rate sensor/lateral accelerometer. After replacement and programming, operate the vehicle within the conditions for running the DTC and verify DTC C0196 28 does not set.
    • If the DTC sets, replace the EBCM.
