INSPECTION PROCEDURE
1 Check cabin.
CHECK:
Check the cabin for any object that might interrupt radio reception on the instrument panel. If such an object
exists, remove it and check if the GPS mark reappears.
HINT:
GPS works using extremely weak radio waves originating from satellites. If the signal is interrupted by ob-
structions or another radio wave, the GPS system may not be able to properly receive the signal.
OK:
Mark appears.
OK Normal operation.
NG
2 Check surroundings.
CHECK:
Check if the vehicle is in a location where GPS signal reception is bad. If the vehicle is in such a place, move
it elsewhere and check if the GPS mark reappears.
HINT:
GPS uses 24 satellites in 6 orbits so that at any time 4 satellites will be in line±of±sight of your vehicle.
GPS signals may not be received, however, based on surroundings, vehicle direction, and time.
