Picture Diagnosis

Start-up procedure
1. Turn the ignition switch to ACC (I), and then press the MENU key on the display. The main menu screen appears.
2. Press and hold the keys in this order: (1) MENU key, (2) MAP/GUIDE key, (3) CANCEL key, and keep them pushed simultaneously. The display changes to the diagnosis menu screen.




SYSTEM LINKS
- During diagnosis, all of the communication lines connecting the components are shown in yellow.
- If the system is OK, all of the communication lines connecting the components will change to green, the screen will indicate "OK", and a tone will sound.
- If there is a problem in the system, the faulty communication line will change to red, the screen will indicate "NG", and a tone will sound.
- The indication on the screen will not change until the ignition switch is cycled. After repairing the system, turn the ignition switch OFF to reset the system, then return to the Diagnosis Menu screen, and run System Links again.




TIRE-CALIBRATE
- The "AUTO TUNING" is factory-set to "ON", and it should remain on. If you find it has been turned OFF, turn it back ON.
- The "TIRE-CAL TUNING" can be used, but it is not recommended. The AUTO TUNING function keeps the system in better tune.
- When you touch "TIRE CHANGE," the display will change to the TIRE SIZE screen. This screen is rarely used because only the standard tire size is listed.




TIRE SIZE
- If the tire-cal factor has been reset, touching the tire size will return the tuning value to the standard value.
