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.
With Navigation
The audio-navigation unit has a coded theft protection circuit. Make sure you have the anti-theft security code before:
- Disconnecting the 12 volt battery.
- Disconnecting audio-navigation unit connector A (24P) and C (8P).
- Removing the No. 1 (15 A) fuse from the under-dash fuse/relay box.
When the audio-navigation unit is reconnected to the power and the ignition switch is turned to ON (II), "CODE" will be displayed. Then, enter the 4-digit anti-theft security code.
When replacing the audio-navigation unit, be sure to give the customer the new anti-theft security code.
