Anti-theft System=NJEL0523DESCRIPTIONNJEL0523S03The 4-digit PIN must be entered when the display shows ªenter your PINº at the time the vehicle is purchased.
RHD ModelsNJEL0523S0301By integrating the Navigation System in the vehicle's interior and linking it to the vehicle's immobilizer system,
the possibility of the Navigation unit being stolen is effectively reduced. Each time the Navigation System is
switched on, the Navigation System will start up communication with the vehicle's immobilizer control unit
(IMMU) and verify an identification code. If communication cannot be established, or the verified code is
incorrect, the Navigation System will lock up showing ªANTI-THEFT FUNCTIONº on the Navigation display.

PIN INITIALIZATION Navigation system will be locked when the vehicle's owner enters the wrong PIN five con-
secutive times.
To release the lock, use ªPIN INITIALIZATIONº.
NAVI ID INITIALIZATION In normal times regulation codes are being communicated between Navigation Control
Unit and Dongle Control Unit.
Use ªNAVI ID INITIALIZATIONº to match the codes when either one has been replaced
due to breakdown or etc.
NOTE:
When any initialization is performed, all NAVI ID and PIN pre-
viously registered will be erased and then must be registered
again.

DRIVING TEST=NJEL0525S03During the driving test, diagnose the system by checking the dif-
ference of symptoms with each sensor ON or OFF.
Test Pattern 1NJEL0525S0301Test method in which current position adjustment is not made
according to GPS data.
+Remove the GPS antenna connector from the NAVI control
unit. Drive the vehicle.
Before driving the vehicle, perform ªAdjust Current Locationº
MODE (EL-496).
Test Pattern 2NJEL0525S0302Test procedure in which map matching is not used.
+Before driving the vehicle, perform ªAdjust Current Locationº
MODE (EL-496). 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.
ExampleNJEL0525S0303
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.
display>
®Perform test patterns 1 and 2.
+Compare the map and the saved driving tracks. The precision
of the saved driving tracks is within several hundred meters.
®Perform test patterns 1 and 2.
+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
