DRIVING TEST
1. DRIVING TEST 1
1. Scroll the map screen to display the area to make correction. Push ªENTERº and select ªCURRENT LOCATION COR-RECTIONº.
2. Correct direction of the vehicle mark.
3. Perform the distance correction of the ªCONFIRMATION/ADJUSTMENTº mode. NOTE:
Normally, adjustment is not necessary because this system has automatic distance correction function. However, when
a tire chain is ®tted, adjustment in accordance with the tire diameter ratio must be made.
4. Are symptoms applicable to the Example of Symptoms Judged Not Malfunction (EL-4218) present after driving the vehicle? YesorNo
Ye s ©Limit of the location detection capacity of the navigation system.
No ©GO TO 2.
2. DRIVING TEST 2
+Did any malfunction occur when the proper test in the following test patterns is performed?
+ Test pattern
Driving test ®nds the difference between the symptoms monitored with and without each sensor.
Ð Test pattern 1: Test method with no GPS location correction Disconnect the GPS antenna connector connected to the NAVI control unit. Accurately adjust the current location and
the direction, then drive the vehicle.
Ð Test pattern 2: Test method with no map-matching Accurately adjust the current location and the direction. Eject the map DVD-ROM from the NAVI control unit with the
ignition switch turned to OFF, then drive the vehicle. After driving, insert the map DVD-ROM back in the unit, display
the track of the vehicle on the map screen and compare it with the actual road con®guration.
+ Sample tests
Ð
Perform test pattern 1.
Ð Perform test pattern 1 and 2.
Compare the track of the vehicle on the map screen and the actual road con®guration. For fairly accurate tracking,
plotting shall be made every several hundred meters.
Ð Perform test pattern 1 and 2.
Drive on a road of which distance is accurately known (by utilizing distance posts on a highway). Calculate the rate of
change (increased/decreased) of the distance by comparing with the actual distance.
Correctio n=1ÐA/B
A: Distance shown on the screen
B: Actual distance YesorNo
Ye s ©+If adjustment is insufficient, perform adjustment again.
+ If any error is found in the map, please let us know.
+ Replace NAVI control unit.
No ©Limit of the location detection capacity of the navigation system.
