Bulletin No.: 09-018/08

Last Issued: 6/26/2008

Subject:
INTEGRATED KEYHEAD TRANSMITTER KEY (IKT) - INCOMPLETE RKE PROGRAMMING AND / OR DTC B1139

APPLICABLE MODEL(S)/VINS
2008 Tribute vehicles produced before January 18, 2008
2008 Tribute Hybrid vehicles produced before January 18, 2008

DESCRIPTION
Some 2008 Tribute and Tribute Hybrid vehicles built on or before January 18, 2008 may exhibit incomplete Remote Keyless Entry (RKE) programming of the Integrated Keyhead Transmitter key (IKT) when adding or replacing IKTs. The Passive Anti-Theft System (PATS) will program and the engine will start and run, only the RKE transmitter function will be inoperative. Diagnostic trouble code (DTC) B1139 may be set.

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

REPAIR PROCEDURE
1. Reboot the IDS to clear memory before reprogramming.

2. Using IDS B55.4 or later software, reprogram the Instrument Cluster (IC) to the latest calibration (refer to "Calibration Information" table shown below) by following the "Module Reprogramming" procedure.
NOTE:
^ Always update the IDS tool first, then follow on-screen instructions to download the needed calibration file for IC reprogramming.
^ It is not necessary to remove any fuses or relays during IC reprogramming when the IDS screen prompts you to do so. You may accidentally stop power to one of the IC terminals and cause the IC to be blanked, or you may receive error messages during the IDS reprogramming procedure.
^ IDS shows the calibration part numbers after programming the IC.
^ Please be aware that IC calibration part numbers and file names listed in any Service Bulletin may change due to future releases of IDS software, and additional revisions made to those calibrations for service related concerns.
^ When reprogramming a IC, IDS will always display the "latest" calibration P/N available for that vehicle. If any calibration has been revised/updated to contain new information for a new service concern/issue, it will also contain all previously released calibrations.
^ When performing this procedure, we recommend that a battery charger be installed on the vehicle battery and turned ON to a maximum charge of no more than 20 AMPS to keep the vehicle battery up to capacity. If you exceed 20 AMPS, it could damage the VCM.

3. Install the IKT that has inoperative RKE function into the ignition and turn to the RUN position for 6 seconds to program the RKE function.

4. Remove the IKT from the ignition and verify RKE buttons function properly.

5. After performing the IC reprogramming procedure, verify the repair by starting the engine and making sure there are no MIL illumination or abnormal warning lights present.
NOTE:
If any DTCs should remain after performing DTC erase, diagnose the DTCs according to the appropriate Troubleshooting section of the Workshop Manual.
