The audio unit has a coded theft protection circuit. Make sure you have the anti-theft security code before:
- Disconnecting the 12 volt battery.
- Disconnecting audio unit connector A (24P) or audio unit connector A (17P).
- Removing the No. 1 (15 A) fuse from the under-dash fuse/relay box.
When the audio unit is reconnected to the power and the ignition switch is turned to ON (II), "ENTER CODE" is displayed. Then, enter the 4-digit or the 5-digit anti-theft security code.
When replacing the audio unit, be sure to give the customer the new anti-theft security code.
