Campaign SC073 - PCM Update for SCAN Tool Communication
Model: Optima(MG)Group: Fuel System(14)
Number: KT2007073101
Date: Friday, August 03, 2007
Area: N. America
Subject:
2006.5MY Optima (MG) 2.4L Calibration Verification Number/Powertrain Control Module Reprogram (SC073)
Description
This service bulletin provides information related to the powertrain control module (PCM) upgrade for 2006.5 MY Optima models produced between 09/29/05 - 9/06/06. Some 2006.5 MY Optima vehicles with a 2.4L engine may experience a delay or communication errors when requesting the Calibration Verification Number (CVN) from the PCM with J1699 protocol devices or generic scantools (non-KMA scantools). During routine emission testing, the vehicle is connected to the emissions testing device and OBDII data is extracted from the vehicle's PCM. If the computer is unable to generate the CVN when prompted, the lack of communication would prevent a successful emissions report.
In order to provide consumer satisfaction, the PCM should be reprogrammed using the GDS download as described in this bulletin.
NOTICE:
^ A fully charged battery is necessary before ECU upgrade can take place. DO NOT connect a battery charger to the vehicle during ECU upgrade. Make sure the blower motor is "OFF" during ECU upgrade.
^ All ECU 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 ECU upgrade procedure.
^ DO NOT start the engine during ECU upgrade.
^ DO NOT turn the ignition key to "OFF" or interrupt the power supply during ECU upgrade.
^ When the ECU upgrade is completed, turn the ignition key "OFF" and wait 20 seconds before starting the engine.
^ ONLY use approved ECU 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 ECM/PCM calibration.

Vehicles Affected:
2006.5 Optima (MG) vehicles produced from September 29, 2005 to September 6, 2006
Service Procedure
1. Connect the power supply cable to the GDS tool.
NOTICE:
If attempting to perform the ECU upgrade with the power supply cable disconnect from the GDS tool, be sure to check that the GDS tool is fully charged before ECU upgrade. If the GDS tool is not fully charged, failure to perform the ECU 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 VCI and the GDS tool.
NOTICE:
When performing the ECU 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 tools vehicle identification number (VIN) screen and configure the vehicle using the VIN AUTO DETECT Function.
6. Once back at the GDS Main Screen, select ECU upgrade from the bottom right-hand corner. Next select Auto Mode, Engine. Perform the ECU upgrade in accordance with normal GDS tool ECU upgrade procedures. This reprogram event will take approximately 18 minutes to complete.
NOTICE:
DO NOT attempt to perform a Manual Mode ECU upgrade unless Auto Mode fails. Always follow instructions given on the GDS tool in either Auto or Manual mode. See table for Manual Mode passwords.
7. When the GDS tool reports that the ECU upgrade has been successfully completed, click OK, turn OFF the ignition key, and wait at least 20 seconds before attempting to start the engine.
8. Check for Diagnostic Trouble Codes using the GDS and erase any DTCs stored in the Engine and Transaxle control modules. Confirm proper shift points of A/T units after reprogramming to reduce customer complaints of excessive shift shock and improper shift points.
