ELECTRONICALLY RETRIEVING AUDIO UNIT SERIAL NUMBERS

ACURA SERVICE NEWS

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) 

1. Turn the ignition switch to ON (II).
2. 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.
3. Turn off the audio unit.
4. 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.
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) 

1. Turn the ignition switch to ACC (I).
2. 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.
3. Turn off the audio unit.
4. 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.
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.
6. 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.
