Circuit/System Verification
WARNING: This page is about a different car, the 2008 Buick LaCrosse and 2008 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.
Ignition ON, verify the scan tool Lateral Acceleration G value in the scan tool VSES scan tool data. If the specified value displays one of the following, a malfunction has occurred:
- Under normal driving conditions, the long time filtered driving direction is straight ahead. The longtime filtered lateral accelerometer value is called the offset. The offset value is higher than 0.23 g.
- The lateral accelerometer signal is limited to an electrical stop of 1.8 g. Verify the lateral accelerometer is not greater than 1.5 g for more than 500 milliseconds.
- During stable driving conditions, the lateral accelerometer signal becomes larger than 0.26 g for more than 2 seconds.
- At standstill, the range of the lateral accelerometer signal is greater than 0.7 g.
- Lateral accelerometer signal cannot change rapidly under normal driving conditions. The lateral accelerometer signal is changing faster than 55 g per second.
