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. In the scan tool Special Functions menu, select ALC Trimset and follow the screen prompts to perform the procedure. Once the process has been completed, the system should be fully functional.
