SYMPTOM/CONDITION:
The driver/memory seat and or driver power seat functions can become intermittently inoperative due to a Memory Seat Module software issue. A software design change has been made to eliminated these intermittent conditions.
DIAGNOSIS:
Using a Scan Tool (StarSCAN(R)) with the appropriate Diagnostic Procedures available in TechCONNECT, verify the driver power seat system is functioning as designed. If DIG's are present record them on the repair order and repair as necessary before proceeding further with this bulletin.
If the vehicle operator describes or experiences the Symptom/Condition, perform the Repair Procedure.
SPECIAL TOOLS / EQUIPMENT REQUIRED:
REPAIR PROCEDURE - USING THE INTERNET TO RETRIEVE THE FLASH FILE:
NOTE:
Before performing this Repair Procedure, the operating software in the StarSCAN(R) must be programmed with software release level 8.05 or higher.
The software release level is visible in the blue header at the top of the StarSCAN(R) screen.
NOTE:
The StarSCAN(R) diagnostic scan tool fully supports Internet connectivity. However, to take advantage of this feature you must first configure the StarSCAN(R) for your dealership's network. Make sure the StarSCAN(R) is configured to the dealership's network before proceeding. For instruction on setting up your StarSCAN(R) for the dealer's network refer to either:
"DealerCONNECT > Service > StarSCAN and StarMOBILE tools > Online Documentation", or refer to the StarSCAN(R) Quick Start Networking Guide. The StarSCAN(R) Quick Start Networking Guide is also available on the website under the "Download Center".
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted.
1. Open the hood and install a battery charger. Using a voltmeter, verify that the charging rate provides 13.2 - 13.5 volts. Set the battery charger to continuous charge. Do not allow the charger to time out during the flash process. Remove the charger from the battery when the flash process is complete.
NOTE:
Do not allow the charging voltage to climb above 13.5 volts during the flash process.
2. Connect the CH9410 StarSCAN(R) ethernet cable to the StarSCAN(R) and the dealer's network drop.
3. Connect the CH9404D StarSCAN(R) vehicle cable to the StarSCAN(R) and the vehicle.
4. Turn the ignition switch on.
5. Power ON the StarSCAN(R).
6. Retrieve the old MSMD part number. Using the StarSCAN(R) at the "Home" screen:
a. Select "ECU View"
b. Touch the screen to highlight the MSMD in the list of modules.
c. Select "More Options
d. Select "ECU Flash".
e. Record the part number at the top of the "Flash MSMD" screen for later reference.
f. Select "Browse for New File". Follow the on screen instructions.
g. Select "Download to Scantool".
h. Select "Close" after the download is complete, then select "Back".
i. Highlight the listed calibration.
j. Select "Update Controller".
k. When the update is complete, select "OK".
7. Verify the part number at the top of the "Flash MSMD" screen has updated to the new part number.
8. **Remove any obstruction from the front of the driver seat cushion.
9. Perform MSMD Standardization using the STARScan.
10. If MSMD standardization fails repeat the standardization process with STARScan.**
NOTE:
Due to the MSMD programming procedure, a DTC may be set in other modules within the vehicle, if so equipped. Some DTC's may cause the MIL to illuminate. From the "Home" screen select "System View". Then select "All DTCs". Press "Clear All Stored DTCs" if there are any DTCs shown on the list.
