Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit/System Testing
2009 Saab 9-7X 5.3iSECTION Circuit/System Testing
- Ignition OFF, disconnect the yaw-rate/lateral accelerometer connector.
- Test the yaw-rate/lateral sensor reference voltage circuit for a short to voltage, short to ground, an open or high resistance.
- If the reference voltage circuit did not test normal, repair the circuit.
- Test the yaw/lateral sensor ground circuit for an open or high resistance.
- If the reference ground circuit did not tests normal, repair the circuit.
- Test the yaw/lateral sensor CAN HI and LO circuit for a short to voltage, short to ground, an open or high resistance.
- If the yaw/lateral CAN HI and LO circuits did not test normal repair the circuit.
- Ignition ON, test the yaw/lateral sensor reference voltage circuit for 5 volts, and the ground circuit for an open or high resistance.
- If the yaw/lateral 5 volt reference and ground circuits test normal replace the yaw/lateral sensor.
- If the yaw/lateral 5 volt reference and ground circuits did not test normal replace the EBCM.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
