Circuit/System Testing
WARNING: This page is about a different car, the 2010 Saturn Sky and 2010 Pontiac Solstice. However, it is still accessible from the selected car via links, so may be relevant.
- Verify that DTC C0186, C0196 or C0292 is not set.
- If any of the DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle .
- Ignition OFF, disconnect the harness connector at the EBCM and the steering angle sensor.
- Ignition ON, test for less than 1 V between the low reference terminal 29 and ground at the EBCM.
- If greater than the specified value, test the low reference for a short to voltage. If the circuit test normal replace yaw/lateral accelerometer sensor.
- Ignition OFF, test for infinite resistance between the 12 V reference circuit terminal 22 and ground at the EBCM.
- If less than the specified value, test the 12 V reference circuit for a short to ground. If the circuit test normal replace yaw/lateral accelerometer sensor.
- Connect the harness connector at the EBCM.
- Test for less than 20 Ω between low reference circuit terminal 6 and ground at the steering angle sensor.
- If greater than the specified range, test the low reference circuit for a short to voltage or an open or high resistance. If the circuit test normal replace the EBCM.
- Ignition ON, test for greater than 10 V between the 12 V reference circuit terminal 1 and ground at the steering angle sensor.
- If less than the specified range test the 12 V for a short to ground or an open or high resistance. If the circuit test normal replace the EBCM.
- If all circuits test normal, replace the steering angle sensor.
