UTD System

Ensure parking lights, low beam headlights, horn and electrical door locks operate. Check SECURITY indicator by ensuring headlights and parking lights are off. Open a window to unlock a door without using a key. SECURITY indicator should not illuminate. Check UTD system fuses. If system is intermittent, check component connectors for tight connections and clean terminals.
