Circuit/System Testing
WARNING: This page is about a different car, the 2010 GMC Canyon and 2010 Chevrolet Colorado. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition OFF, disconnect the harness connector at the yaw/lateral accelerometer sensor.
- Test for less than 1 Ω of resistance between the low reference circuit terminal 1 and ground.
- If greater than the specified range, test for an open/high resistance in the low reference circuit.
- Ignition ON, test for ignition voltage between the ignition circuit terminal 4 and the low reference circuit terminal 1.
- If not the specified value, test the ignition circuit for a short to ground or an open/high resistance.
- Ignition OFF, disconnect the harness connector at the EBCM.
- If all circuits test normal, replace the yaw/lateral accelerometer sensor. If DTC resets replace the EBCM.
