Anti-Theft Feature
Anti-Theft Feature
The audio-navigation unit has an anti-theft protection circuit. When one of the following occurs, the unit enters the anti-theft mode.
- Disconnecting the battery.
- Disconnecting audio-navigation unit connector F (18P).
- Removing the No. A1-1 (120 A) fuse, the No. A3-3 (60 A) fuse, or the No. A6 (15 A) fuse from the under-hood fuse/relay box.
After service, reconnect power to the audio-navigation unit, and press the engine start/stop button to select the ON mode. There are two ways to exit the anti-theft mode:
- While Enter PIN Code screen is displayed, press and hold the POWER (
- Enter the 5-digit anti-theft code. If the input of code fails 10 times in a row, the screen is locked for 60 minutes.
If the code is unavailable, you can get the code from the iN using the audio-navigation system serial number. The system serial number can easily be obtained without removing the audio-navigation unit. To get the serial number and the code:
- Do the System Diagnostic Mode , and select Detail Information & Setting, then select ECU Info in Unit Check menu. The audio-navigation unit serial number is displayed.
- Use the Anti-theft code inquiry option on the iN to look up the 5-digit anti-theft code. The iN may display more than one code for a given serial number. This is because serial numbers are not unique. You may have to try more than one 5-digit code. If no code is shown, or if the code(s) given do not work in the audio-navigation unit, contact the Automobile Warranty department.
Alternatively, you can find the serial number on the upper label which is located on the audio-navigation unit in the dash.
The HDD and the audio-navigation unit are mated to each other and can only be mated to a new unit. If someone tried to put a stolen HDD in another audio-navigation unit, or insert their HDD in a stolen audio-navigation unit, the two components cannot mate and a HDD read error appears on the display.
When replacing the audio-navigation unit, be sure to give the client the new anti-theft security code.
