TROUBLE DIAGNOSES FOR SELF-DIAGNOSTIC ITEMSABS
Wheel Sensor or Rotor (Cont'd)
BR-79

GPS signal reception conditions are good. However, the position mark does not return to its proper
position.
+The system senses the vehicle location with an error of approximately 100 m (328 ft). Due to the limita-
tion of precision, the position marker may be inaccurate even if the GPS signal reception condition is good.
+The navigation system uses GPS data to determine vehicle location. GPS data is compared with other
locational sensing data during the map matching process. The system decides which data is more pre-
cise and uses that data.
+When the vehicle is stationary, GPS data cannot be used to make system corrections.
Area designations on the map display and the BIRDVIEW
Tdisplay differ.
To prevent the display from becoming congested, alphanumeric information is abridged.
[No problem]
Correct position of your vehicle is not displayed.
Vehicle position changed after ignition key was turned to the OFF position (Vehicle is transported on car ferry,
car train, or by some other means).
[Operate vehicle for short time under GPS receiving conditions.]
The display does not change to night-time mode even though the light switch has been turned ON.
Lights have been turned on. In ªDISPLAY CHANGEº mode, night-time mode on display has been switched to
day-time mode and still is.
[Turn lights on again. Set the display to night-time mode. Refer to EL-494.]
Map does not scroll even though the position of your vehicle is changed.
Present area does not appear on the display.
[Press the ªMAPº switch.]
Vehicle position marker does not appear.
Present area does not appear on the display.
[Press the ªMAPº switch.]
The map surface precision display (GPS satellite marker) still remains gray.
Vehicle is parked inside a building or in the shadow of a large building. This intercepts the GPS signal.
[Move the vehicle to a more open position.]
GPS signal is not received because objects are placed on the rear parcel shelf.
[Remove objects from the rear parcel shelf.]
GPS satellite position is bad.
[Wait until GPS satellite position improves.]
Vehicle position precision is bad.
The map surface precision display (GPS satellite marker) still remains gray.
[Refer to ªThe map surface precision display (GPS satellite marker) still remains grayº item (Symptoms)]
Vehicle speed and elapsed distance is calculated from the vehicle speed pulse. This pulse is dependent upon
tire size. If tire chains are used on the vehicle, accuracy will be affected (pulse rate will be too fast or too slow).
The same is true if the system installed to your vehicle is removed and installed on another vehicle.
[Drive the vehicle at a speed higher than 30 km/h (19 MPH) for approximately 30 minutes. Automatic read-
justment should occur. If it does not (remains too fast or too slow), distance calibration is required. Or, drive
the vehicle for a short distance. Perform ªSPEED CALIBRATIONº (EL-488). After removing the tire chains,
sensing accuracy may recover by itself.]
Bad map data or system defect (same error consistently occurs in the same area)
ROUTE SEARCH/ROUTE GUIDENJEL0526S03+If the present location or the destination location is displayed in the avoid area, it is not possible to search
routes.
+If the avoid area is set to wide range area, it may not be possible to find appropriate routes or search for
alternate routes.
+The automatic re-route calculates a return to the original route. Because of this, it may not be possible to
search appropriate new routes. If you deviate from the original route and wish to select an appropriate new
route, touch ªRoute Calculationº.
+The automatic re-route function may sometimes require considerable time.
+Displayed route number and directional information at a highway junction may differ from the information
posted on the actual road signs.
+Displayed street name information at a highway exit may differ from the information posted on the actual
road signs.
+Street name information displayed on the enlarged intersection map may differ from the information posted
on the actual road signs.

VALVE SEATSNJEM0065S10+Before starting this check, confirm that the dimensions of valve
guides and valves are as specified.
+Apply red lead primer on contacting surfaces of valve seat and
of valve face to examine the conditions of contacting surfaces.
+Check that the paint on contacting surfaces is continuous
along the entire circumference.
+If there are abnormal indications, grind the valve and check the
contact again. If abnormal indications still persist, replace
valve seat.

REPLACING VALVE SEAT FOR SERVICE PARTSNJEM0065S111. Bore out old seat until it collapses. Boring should not continue
beyond the bottom face of the seat recess in cylinder head. Set
the machine depth stop to ensure this.
2. Ream cylinder head recess for service valve seat.
Oversize [0.5 mm (0.020 in)]:
Intake 30.500 - 30.516 mm (1.2008 - 1.2014 in)
Exhaust 29.500 - 29.516 mm (1.1614 - 1.1620 in)
Be sure to ream in circles concentric to the valve guide
center.
This will enable valve seat to fit correctly.
