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 and lateral acceleration sensor connector.
- Ignition OFF, test for less than 1 ohm of resistance between the low reference circuit terminal 6 and ground.
- If greater than 1 ohm, test the low reference circuit terminal 6 and the EBCM ground circuit terminal 16 for a short to voltage or an open/high resistance. If the circuits test normal, replace the EBCM.
- Test the lateral accelerometer signal circuit terminal 2, the 5-volt reference circuit terminal 1, and the low reference circuit terminal 6 for an open/high resistance or a short to voltage or ground.
- If all circuits test normal, replace the yaw rate sensor/lateral acceleration sensor, and clear the yaw rate sensor offset value in the EBCM.
- If the DTC sets again after replacing the yaw rate sensor/lateral acceleration sensor, replace the EBCM.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • 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.
