Circuit/System Testing
- If DTC C0292 is set, diagnose that DTC first.
- Ignition OFF, disconnect the yaw and lateral accelerometer sensor connector.
- Ignition OFF, test for less than 1 ohm between the ground circuit terminal and ground.
- If greater than 1 ohm, test the ground circuit terminal and the EBCM ground circuit terminal for a short to voltage or an open/high resistance. If the circuits test normal, replace the EBCM.
- Test the lateral accelerometer signal circuit terminal, the 5-volt reference circuit terminal, and the ground circuit terminal for an open/high resistance or a short to voltage or ground.
- If all circuits test normal, replace the yaw and lateral accelerometer sensor, and clear the yaw rate sensor offset value in the EBCM.
- If the DTC sets again after replacing the yaw and lateral accelerometer sensor, replace the EBCM.
