2. Place the vehicle on a flat level surface. Ensure that the suspension is in the normal resting position. With a scan tool, perform the ALC Trimset procedure by following the screen prompts.
3. With a scan tool, perform the suspension Bumpstop setup procedure by following the screen prompts.

Once the process has been completed, the system should be fully functional.
