Suspension Position Calibration (With Z95)

Automatic Level Control (ALC) Trimset Procedure

If the system is functioning abnormally, performing the Bumpstop and ALC Trimset recalibration procedures may correct the condition. When a system component has been replaced, the Bumpstop setup and ALC Trimset procedures must be performed.

1. 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.
2. Raise the vehicle off the ground enough to allow the suspension to fully extend. 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.
