Circuit Description

This is the TRAC & VSC control main switch. When the VSC OFF switch is pushed on, TRAC & VSC control goes off and the VSC OFF indicator lights up. Also, the VSC OFF indicator light is "ON" when the VSC system is at the fail safe control. Turn the ignition switch OFF. Ensure TRAC & VSC control comes on when the ignition switch turns ON the next time.
