Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Entering Security Code
The navigation system and audio unit have a coded theft protection circuit. Be sure to get the customer's anti-theft security codes number before;
- Disconnecting the battery
- Disconnecting the navigation unit 8P connector
- Removing the No. 7 (7.5 A) fuse from the under-dash fuse/relay box
After service, reconnect power to the navigation unit, and turn the ignition switch ON (II). Enter the 4-digit anti-theft security code, then select "Done".
When replacing the navigation unit or audio unit, be sure to give the customer the new anti-theft security code.
