LOCATION CORRECTION”.
2. Correct direction of the vehicle mark.
3. Perform the distance correction of the CONFIRMATION/ADJUSTMENT mode.

tion. However, when a tire chain is fitted, adjustment in accordance with the tire diameter ratio must be
made.

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, 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, then drive the vehicle. After driving, insert the map DVD-ROM back

Perform test pattern 1 & 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 & 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.
