IMPORTANT:
DEALERS MUST PERFORM THIS CAMPAIGN ON ALL AFFECTED VEHICLES PRIOR TO CUSTOMER RETAIL DELIVERY AND WHENEVER AN AFFECTED VEHICLE IS IN THE SHOP FOR ANY MAINTENANCE OR REPAIR.

IMPORTANT:

DESCRIPTION:

The Electronic Stability Control (ESC) of some 2006 Sonata vehicles equipped with 3.3 Liter engines may be programmed to be too sensitive, causing inadvertent brake application on banked curves.

To correct this condition, the ESC ECU may be reprogrammed using the Hi-Scan Pro as described in this bulletin.

VEHICLES AFFECTED:

^ Model: 2006 SONATA 3.3L vehicles with ESC

^ Affected vehicle production date range:

^ Produced from May 5, 2005 through June 10, 2005





ESC ECU SPECIFICATIONS:

CAUTIONS BEFORE REPROGRAMMING:

1. Perform reprogramming with the ignition key in the "ON" position.

2. Be careful not to disconnect any cables connected to the vehicle or Hi-Scan Pro during reprogramming.

WARNING:

^ When reprogramming the SONATA ESC ECU, the manual reprogramming mode [error mode] is not available.

^ If ESC ECU reprogramming is interrupted during the "ESC ECU software data download" process as a result of cable disconnection, power interruption or battery discharge, the ESC ECU must be replaced.

3. Do not start the engine during reprogramming.

4. Do not turn the ignition key OFF during reprogramming.

5. When the reprogramming is completed, wait for about 20 seconds and then start the engine to confirm proper operation of the vehicle.

ESC ECU REPROGRAMMING:

NOTE:
Verify that the vehicle was manufactured within the affected production date range and the campaign is open per the DCS interactive screen.

1. Attach the Data Link Connector (DLC) cable to the Hi-Scan Pro main body and securely tighten the two bolts.

2. Remove the system software card from the Hi-Scan Pro and insert the reprogramming software card with the new ECU program into the Hi-Scan top slot.





3. Plug the DLC cable from the Hi-Scan Pro into the data link connector (16-pin connector) under the instrument panel on the driver's side.

4. Turn the ignition switch to the ON position. (Do not start the engine).

5. Turn the Hi-Scan Pro ON and press ENTER.





6. Select option "61. SONATA ESP LOGIC IMPROVEMENT" and press ENTER.





7. Select option "01. SONATA ESP LOGIC [AUTO MODE]" and press ENTER.

8. Enter "1229" as the password for automatic reprogramming mode and press ENTER.

9. The Hi-Scan Pro will establish communication, check the ESC ECU ID and reprogram the ESC ECU automatically.

CAUTION:
IF "ALREADY REPROGRAMMED. PRESS ANY KEY" is displayed on the Hi-Scan Pro screen in step 9, exit the ESC ECU reprogramming procedure by pressing any key. The ESC ECU reprogramming has previously been completed on this vehicle.

10. Turn the ignition key OFF and ON. Press ENTER.





WARNING:
Be careful not to interrupt the reprogramming.

^ If the reprogramming is interrupted during the "BASIC AND FUNCTION DOWNLOAD" process, repeat the reprogramming procedure again.

^ If the reprogramming is interrupted during the "ECU SW DATA DOWNLOAD" process, the ESC ECU must be replaced.





NOTE:

^ The Hi-Scan Pro detects the current ESC ECU ID, assigns the new ESC ECU ID and displays them on the Hi-Scan Pro screen.

^ Check the ESC ECU ID displayed on the Hi-Scan Pro screen to verify that the correct ESC ECU software is being downloaded. Refer to the "ESC ECU SPECIFICATIONS TABLE" in this TSB.

11. Turn the ignition key OFF and ON. Press ENTER.

12. When the reprogramming is completed successfully, turn the ignition key to the OFF position for about 20 seconds and start the engine to confirm proper operation of the vehicle.

13. Check for diagnostic trouble codes using the Hi-Scan Pro with the system software card and erase any trouble codes.

EXPLANATION OF ERROR MESSAGE:

1. "INVALID PASSWORD": Please enter the exact password again.

2. "ALREADY REPROGRAMMED" or "INCORRECT TARGET ID": This reprogramming has previously been completed on this vehicle or the ESC ECU is not subject to this reprogramming procedure.

3. "COMMUNICATION ERROR, PLEASE CHECK THE SYSTEM": In this case, the ESC ECU must be replaced.
