nals from the carº MODE.EL-285
Radio wave of GPS cannot
be received. (GPS marker
on the display does not
become green color.)1. Is there anything obstructing the GPS antenna on the rear parcel finisher?
(GPS antenna located under the rear parcel finisher.)Ð

DRIVING TEST=NJEL0525S03During the driving test, diagnose the system by checking the dif-
ference of symptoms with each sensor ON or OFF.
Test Pattern 1NJEL0525S0301Test method in which current position adjustment is not made
according to GPS data.
+Remove the GPS antenna connector from the NAVI control
unit. Drive the vehicle.
Before driving the vehicle, perform ªAdjust Current Locationº
MODE (EL-298).
Test Pattern 2NJEL0525S0302Test procedure in which map matching is not used.
+Before driving the vehicle, perform ªAdjust Current Locationº
MODE (EL-298). With the ignition switch OFF and the map
CD-ROM removed from the NAVI control unit, drive the
vehicle. After driving the vehicle, reinstall the map CD-ROM.
Compare the saved driving tracks for the vehicle's current loca-
tion with roads on the map.
ExampleNJEL0525S0303 when driving in the same area. Determine if this is the result of the
map matching function or the GPS function.>
®Perform test pattern 1.
display>
®Perform test patterns 1 and 2.
+Compare the map and the saved driving tracks. The precision
of the saved driving tracks is within several hundred meters.

®Perform test patterns 1 and 2.
+Make adjustments by driving the vehicle over a known course
(highway or other road where distances are clearly marked).
Calibrate the distance against the known distance. Use the
formula below.
Calibration value = Screen display distance/Actual distance

EXAMPLE OF CURRENT VEHICLE POSITION MARKER ERROR=NJEL0526S02The navigation system reads the vehicle distance and steering angle data. Because the vehicle is moving,
there will be an error in the current position indication. After the error appears, drive the vehicle for a short
distance. Stop the vehicle. If the position marker does not return to its original position, perform ªAdjust Cur-
rent Locationº MODE (EL-298).
