Suspension Position Calibration (Without Z95)

Suspension Position Calibration

Automatic Level Control (ALC) Trimset Procedure

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

1. Ensure that the vehicle has a full tank of fuel or add sufficient weight to the rear of the vehicle to simulate a full tank of fuel.
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.

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