SERVICE INFORMATION
If you remove power from an audio unit with theft protection, you've got to enter a unique five-digit antitheft code into the unit or it doesn't work. This anti-theft code and the audio unit's eight-digit serial number are listed on the anti-theft ID card that comes with the vehicle. If this card gets lost, you need to get the anti-theft code from the iN. In order to do that, you first need to get the audio unit serial number. Some Acura models let you do that electronically. Here's how:
Method 1 (all applicable models except '04-07 TSXs with the navigation system)
- Turn the ignition switch to ON (II).
- Turn on the audio unit, and make sure you see COdE in the display. If you don't see this message, pull the backup fuse for 1 minute , and then go back to step 1.
- Turn off the audio unit.
- Press and hold the 1 and 6 preset buttons, then turn on the audio unit. The display toggles between two screens. The first screen displays a U and the first four digits of the serial number (for example, U2200 ). The second screen displays an L and the last four digits of the serial number (for example, L0055 ). Ignore the U and L , and write down all eight digits. Then go to step 5.
- Enter the eight-digit serial number into the iN to get the anti-theft code.
- From the main menu, click on SERVICE .
- Click on Vehicle Information .
- Click on Anti-Theft Code Inquiry .
- Select RADIO/CD from the Product list, enter the serial number from the audio unit display in the Serial Number field, and click on Submit . Youll see the five-digit anti-theft code for that audio unit.
- Enter the anti-theft code into the audio unit. Refer to the applicable O/M for details.
Method 2 ('04-07 TSXs with the navigation system)
- Turn the ignition switch to ACC (I).
- Turn on the audio unit, and make sure you see COdE in the upper display. If you dont see this message, pull the backup fuse for 1 minute , and then go back to step 1.
- Turn off the audio unit.
- Press and hold the top halves of the SEEK/SKIP and CH/DISC bars, and then press and release the PWR/VOL knob. This display toggles between two screens. The first screen displays a U and the first four digits of the serial number (for example, U2200 ). The second screen displays an L and the last four digits of the serial number (for example, L0055 ). Ignore the U and L , and write down all eight digits. Then go to step 5.
- Enter the eight-digit serial number into the iN to get the five-digit anti-theft code.
- From the main menu, click on SERVICE .
- Click on Vehicle Information .
- Click on Anti-Theft Code Inquiry .
- Select RADIO/CD from the Product list, enter the serial number from the audio unit display in the Serial Number field, and click on Submit . Youll see the five-digit anti-theft code for that audio unit.
- Use the TUNE knob to enter the first four digits of the anti-theft code into the audio unit. When you turn the TUNE knob, COdE disappears, and a single digit is displayed. Turn the knob left or right to select each of the anti-theft code digits. When you press the TUNE knob, the system beeps and accepts each digit as it spells out COdE on the display.
