DRIVING TEST
=NBEL0234S03
During the driving test, diagnose the system by checking the dif-
ference of symptoms with each sensor ON or OFF.
Test pattern 1
Test method in which current position adjustment is not made
according to GPS data.
I
Remove the GPS antenna connector from the display & NAVI
control unit. Drive the vehicle.
Before driving the vehicle, perform “ADJUST CURRENT
LOCATION” (EL-411).
Test pattern 2
Test procedure in which map matching is not used.
I
Before driving the vehicle, perform “ADJUST CURRENT
LOCATION” (EL-411). With the ignition switch OFF and the
map CD-ROM removed from the display & 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 location with roads on the map.
Example
<The position marker consistently indicates the wrong position
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.
<To verify the accuracy of the road configuration shown on the
display>
,
Perform test patterns 1 and 2.
I
Compare the map and the saved driving tracks. The precision
of the saved driving tracks is within several hundred meters.
<To make distance calibration and adjustments>
,
Perform test patterns 1 and 2.
I
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
