Component Testing
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.
- Install a 3A fused jumper wire between the Yaw and Lateral Acceleration Sensor 5-volt reference terminal 1 and 5 volts. Install a jumper wire between the low reference terminal 6 and ground.
- Sweep the sensor through the entire range while monitoring the resistance between the signal circuit terminal 4 and the low reference circuit terminal 6. The voltage should vary between 2.1-2.9 volts without any spikes or dropouts.
- If not within the specified range or is erratic, replace the Yaw and Lateral Acceleration Sensor.
