DRIVING TEST
=NHEL0303S03
During the driving test, diagnose the system by checking the dif-
ference of symptoms with each sensor ON or OFF.
Test Pattern 1
NHEL0303S0301
Test method in which current position adjustment is not made
according to GPS data.
I
Remove the GPS antenna connector from the NAVI control
unit. Drive the vehicle.
Before driving the vehicle, perform “Adjust Current Location”
MODE (EL-501).
Test Pattern 2
NHEL0303S0302
Test procedure in which map matching is not used.
I
Before driving the vehicle, perform “Adjust Current Location”
MODE (EL-501). 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.
Example
NHEL0303S0303
<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
