Circuit/System Testing
WARNING: This page is about a different car, the 2008 Pontiac Torrent and 2008 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition OFF, disconnect the harness connector at the Yaw Rate/Lateral Accelerometer sensor.
- Test for less than 1 ohm of resistance between the low reference circuit terminal 5 and ground.
- If greater than the specified range, test for an open/high resistance in the low reference circuit. If the circuit tests normal, replace the EBCM.
- Ignition ON, test for ignition voltage between the ignition circuit terminal 3 and the low reference circuit terminal 5.
- If not the specified value, test the ignition circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM.
- Ignition OFF, disconnect the harness connector at the EBCM.
- Test for infinite resistance between the low reference circuit terminal 29 and ground.
- If greater than the specified value, test the low reference circuit for a short to ground.
- If all circuits test normal, replace the Yaw Rate/Lateral sensor.
