Warranty Extension and Out-of-Warranty Repair: Audio-HVAC Display Is
Dim or Dark
(Supersedes 04-021, Warranty Extension: Audio-HVAC Display is Dim or Dark, dated May 7, 2008, to revise the information marked by the black bars and asterisks)
*REVISION SUMMARY
^ Under BACKGROUND, PARTS INFORMATION, and Parts Manager, information about out-of-warranty parts was added.
^ A new section, OUT-OF-WARRANTY REPAIR ORDERING AND CORE RETURN INFORMATION, was added.*
BACKGROUND
NOTE:
Because of a class action settlement, the warranty extension coverage for the audio unit display on 2004 TSXs purchased or leased between April 13, 2002, and November 7, 2006, is now 7 years or 105,000 miles, whichever occurs first. For more information, refer to Service Bulletin 06-050, Warranty Extension: Vehicle Warranty Mileage.
In some audio units, a component failure on the PCB (printed circuit board) could cause the audio display to become dark or dim and prevent the audio/HVAC panel buttons from illuminating. On vehicles with navigation systems, this condition does not affect the display, but the navigation panel buttons do not illuminate.
To ensure that clients have adequate warranty coverage for this potential problem, Acura is increasing the warranty on the audio unit display to 7 years or 100,000 miles, whichever occurs first. For other defects the standard 4 years or 50,000 miles warranty applies, whichever occurs first.
*If the warranty extension has expired, refer to PARTS INFORMATION to determine which part number you need to order. If you order a Client Contribution P/N, refer to PIB B10-0009, Client Pay POB Program:
Audio-HVAC Display Is Dim or Dark, for more information about prices, ordering, and core return.*
CLIENT NOTIFICATION
Owners of affected vehicles received a notification of this warranty extension. An example of the client notification is at the end of this service bulletin.
CORRECTIVE ACTION
If confirmed by your diagnosis, replace the PCB (printed circuit board) inside the audio unit. The PCB core must be returned for credit.
*OUT-OF-WARRANTY REPAIR ORDERING AND CORE RETURN INFORMATION
For information on how to order the PCB and return the core to Remanufactured Parts Operations, refer to PIB B10-0009, Client Pay POB Program: Audio-HVAC

PCB HANDLING PRECAUTIONS
NOTICE
Static electricity can damage the components on the PCB. Always follow proper handling procedures.
^ Handle the PCB only by the edges of the board.
^ Always use the anti-static mat and wrist strap when doing this repair.
To prevent damage to the thermal pad, don't remove the protective cover until you are instructed to do so.
REPAIR PROCEDURE A (WITHOUT NAVIGATION)
NOTE:
^ Before you replace a PCB, refer to the PCB HANDLING PRECAUTIONS.
^ To replace a PCB, you need the ESD/anti-static mat from the PCB tool kit (P/N 07AAZ-SDAA170) and a clean work surface.
^ Before you open the audio unit or handle the replacement PCB, attach the wrist strap (included in the PCB tool kit) around one of your wrists and attach the alligator clip to the ESD mat.
^ Replacement PCBs come with a new serial number label, an anti-theft code card, and two labels with the new serial number and anti-theft code. Apply the serial number label to the anti-theft card, and give the card to the client. Make sure the client knows the importance of keeping the anti-theft code card in a safe place. Advise them to discard the original anti-theft code card.
^ Check the radio and HVAC functions before you begin. Make sure you note all functions are working before you begin to prevent unnecessary troubleshooting. This repair is for illumination problems only. Other problems and repairs are not covered by this bulletin.
