Diagnostic Aids

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.

If the yaw and lateral acceleration sensor is disconnected, DTCs will set and the EBCM will not provide 5-volt reference.
The yaw rate and lateral accelerometer sensors are located in one unit and cannot be serviced separately.
A poor ground connection for the EBCM may cause this DTC to set.
