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.
IMPORTANT:
It is important to check the wiring harness connections to the following items:
- EBCM
- Brake pressure sensor
- Steering angle sensor
- Yaw/lateral accelerometer sensor
- LF wheel speed sensor (WSS)
- RF WSS
- LR WSS
- RR WSS
- During diagnosis, park the vehicle on a level surface.
- Inspect the vehicle for proper alignment. The car should not pull in either direction while driving straight on a level surface.
- Find out from the customer the conditions under which the DTC was set. This information will help to duplicate the failure.
- The Snapshot function on the scan tool can help find an intermittent DTC.
