Circuit/System Testing
- Ignition ON, observe the DTC information with the scan tool.
- Ignition OFF, disconnect the yaw rate and lateral accelerometer sensor connector.
- Ignition OFF for 5 minutes, test for less than 1 ohm of resistance between the low reference circuit terminal 6 and ground.
- If greater than the specified value, test the low reference circuit for an open/high resistance. If the circuit test normal, replace the EBCM.
- Test the lateral accelerometer 12 volt reference circuit terminal 1 for a short to voltage or ground.
- If all circuits test normal, replace the yaw rate sensor and lateral accelerometer sensor, cycle the ignition switch and perform the yaw rate sensor reference table reset procedure.
- If the DTC sets again after replacing the yaw rate sensor and lateral accelerometer sensor, replace the EBCM.
