Unit Check (Quick Check): GPS

If the GPS (Antenna) is NG, then check the entire GPS antenna wire from the navigation unit to the GPS antenna. If the wire is crushed or damaged, substitute a known-good GPS antenna (see GPS ANTENNA REMOVAL/INSTALLATION  ). If the diagnosis reads OK, replace the original GPS antenna (see GPS ANTENNA REMOVAL/INSTALLATION  ). If the diagnosis still reads NG (Antenna), replace the navigation unit (see NAVIGATION UNIT REMOVAL/INSTALLATION  ).
