Anti-theft Feature
The navigation system has a coded theft protection circuit. Be sure to get the customer's 4-digit anti-theft security code before;
- Disconnecting the battery
- Disconnecting the navigation unit 8P connector
- Removing the INTR LIGHT (10 A) fuse from the passenger's under-dash fuse/relay box
After service, reconnect the power to the navigation unit, and turn the ignition switch ON (II). Enter the 4-digit anti-theft security code, then select "Done".
If you cannot find the 4-digit anti-theft code, you must look it up using the Interactive Network (iN). To do this select Service, Vehicle Information, Anti-Theft Code Inquiry, and then select the "Navigation" choice from the "Product" dropdown box. You can obtain the navigation unit serial number from the diagnostic screen "Navi ECU", found under the navigation diagnostic menu item "Unit Check" (see NAVI SYSTEM LINK ). Alternately, the serial number can be found on the underside of the navigation unit located under the passenger seat.
When replacing the navigation unit, be sure to give the customer the new anti-theft security code.
