Subject:
INOPERATIVE RKE TRANSMITTER (KEY FOB)/DISCHARGED KEY FOB BATTERY

APPLICABLE MODEL(S)/VINS
2008 B-Series vehicles with VINs produced between June 4, 2007 and December 14, 2007

DESCRIPTION

Some 2008 vehicles equipped with a remote keyless entry (RKE) may exhibit an inoperative RKE transmitter (key fob) due to a discharged battery in the key fob. This may be caused by an internal issue with the key fob software.

Customers having this concern should have their vehicle repaired using the following repair procedure.

REPAIR PROCEDURE

1. Verify customer concern.

NOTE:
Performing this procedure will have no effect on key fob range.

2. Refer to APPLICABLE MODELS for build date range.

^ If the vehicle was built within the date range, continue with this Service Bulletin.

^ If the vehicle was NOT built within the date range, continue normal diagnostics using the Workshop Manual.





3. Look at the back of the key fob.

^ If the part number for the key fob (3 button) is 8L3T-15K601-AA, continue with this Service Bulletin.

^ If the part number for the key fob (3 button) is NOT 8L3T-15K601-AA, continue normal diagnostics using the Workshop Manual.





4. Using a thin coin, open the key fob and check the manufacturer's date code sticker. The first three digits are the day of the year and the last digit is the year.

^ If the first three digits are equal to or between 005 and 306 (5th day through 306th day) and the last digit is 7 (year), continue with this Service Bulletin.

^ If the number is outside the specified range, continue normal diagnostics using the Workshop Manual.

5. Check if the battery in the key fob is discharged. If it is, replace the key fob and program the new RKE transmitter using the IDS RKE Transmitter Programming Procedure. If all remotes for the vehicle are present, refer to MS3 online instructions or Workshop Manual section 09-14 REMOTE KEYLESS ENTRY (RKE) TRANSMITTER PROGRAMMING to program the remotes without using IDS.

NOTE:
Key fobs replaced under Warranty will be requested for analysis and verification of the date code.

6. Verify repair.
