MODEL:
Optima (MG)
Rondo (UN)

DATE: December 2007

SUBJECT:
2.7L (MU) OPTIMA (MG) AND RONDO (UN) P0110 REPROGRAM

This service bulletin provides information related to the powertrain control module (PCM) upgrade for all 2.7L (Mu) powertrain control modules. This PCM reprogramming is applicable to all 2006.5 - 2007 Optima (MG) models produced between 12/09/2005 - 06/05/2007 and 2007 Rondo (UN) models produced between 09/06/2006 - 07/05/2007. Some vehicles with a 2.7L engine may experience a malfunction indicator lamp (MIL) illumination with DTC P0110 (Intake Air Temperature Circuit Malfunction), even though no actual circuit malfunction exists. To correct this condition, the PCM should be reprogrammed using the GDS download as described in this bulletin before attempting to repair this concern.





Note:
Global Diagnostic System (GDS) users should access the "Notice" function from the GDS Main Screen for instructions regarding ECU upgrade events.

*NOTICE:
^ A fully charged battery is necessary before PCM upgrade can take place. DO NOT connect a battery charger to the vehicle during PCM upgrade. Make sure the blower motor is "OFF" during PCM upgrade.

^ All PCM upgrades must be done with the ignition key in the "ON" position.

^ Be careful not to disconnect any cables connected to the vehicle or GDS during the PCM upgrade procedure.

^ DO NOT start the engine during PCM upgrade.

^ DO NOT turn the ignition key "OFF" or interrupt the power supply during PCM upgrade.

^ When the PCM upgrade is completed, turn the ignition key "OFF" and wait 20 seconds before starting the engine.

^ ONLY use approved PCM upgrade software designated for the correct model, year and engine size. Failure to do so may create other driveability issues due to the use of the incorrect PCM calibration.





ROM ID INFORMATION TABLE

1. Connect the power supply cable to the GDS tool.

*NOTICE:
If attempting to perform the PCM upgrade with the power supply cable disconnected from the GDS tool, be sure to check that the GDS tool is fully charged before PCM upgrade. If the GDS tool is not fully charged, failure to perform the PCM upgrade may occur. Therefore, it is strongly recommended that the power supply connector be connected to the GDS tool.

2. Connect the USB cable between the Vehicle Communications Interface (VCI) and the GDS tool.

*NOTICE:
When performing the PCM upgrade using the GDS tool, wireless communication between the VCI and GDS tool is not available. Therefore, be sure to connect the USB cable between the VCI and the GDS tool.

3. Connect the Main 16-pin DLC cable (GHDM - 241000) to the VCI.





4. Connect the Main 16-pin DLC cable (GHDM - 241000) to the OBD-II connector, located under the driver's side of the instrument panel.

5. With the ignition key ON, turn ON the VCI and GDS tool. Access the GDS vehicle identification number (VIN) screen and configure the vehicle using the VIN AUTO DETECT Function.

6. At the GDS Main Screen, select ECU UPGRADE from the menu buttons located on the bottom of the screen Next, select Auto Mode, Engine.

7. Perform the PCM upgrade in accordance with normal GDS tool PCM upgrade procedures.

Note:
Global Diagnostic System (GDS) users should access the "Notice" function from the GDS Main Screen for instructions regarding ECU upgrade events.





* NOTICE:
Do NOT attempt to perform a Manual Mode PCM upgrade unless Auto Mode fails. Always follow the instructions given on the GDS tool in either Auto or Manual mode. Refer to table above for Manual Mode passwords.

8. When the GDS tool reports that the PCM upgrade has been successfully completed, click OK, turn OFF the ignition key, and wait at least 20 seconds before attempting to start the engine.

9. Check for Diagnostic Trouble Codes using the GDS and erase any DTCs stored in the Engine and Transaxle control modules.

10. Confirm proper shift points of A/T units after reprogramming to reduce customer complaints of excessive shift shock and improper shift points.

AFFECTED PRODUCTION RANGE:
2.7L - equipped 2006.5 - 2007 Optima (MG) models produced between 12/09/2005 - 06/05/2007 and 2007 Rondo (UN) models produced between 09/06/2006 - 07/05/2007
