Driving TestAKS007KG
1. DRIVING TEST 1
1. Scroll the map screen to display the area to make correction. Press “ENTER” and select “CURRENT LOCATION CORRECTION”.
2. Correct direction of the vehicle mark.
3. Perform the distance correction of the CONFIRMATION/ADJUSTMENT mode. Note: Normally, adjustment is not necessary because this system has automatic distance correction func-
tion. However, when a tire chain is fitted, adjustment in accordance with the tire diameter ratio must be
made.
4. Are symptoms malfunctioning to the AV- 1 7 1 , "
Example of Symptoms Judged Not Malfunction" present
after driving the vehicle?
YES or NO
YES >> 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 finds the difference between the symptoms monitored with and without each sensor.
–Test pattern 1: Test method with no GPS location correction
Disconnect GPS antenna connector (GT5) connected to the NAVI control unit. Accurately adjust the cur-
rent location and the direction, and then drive the vehicle.
–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 ignition switch turned to OFF, and 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
configuration.

Sample tests
– matching or by GPS>
Perform test pattern 1.
–;
Perform test pattern 1 and 2.
Compare the track of the vehicle on the map screen and the actual road configuration. For fairly accurate
tracking, plotting shall be made every several hundred meters.
–;
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.
Correction = A/B
A: Distance shown on the screen
B: Actual distance
YES or NO
YES >>
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.
