ECM REPROGRAMMING FOR ENGINE HESITATION IN THE MORNING AND DIAGNOSTIC TROUBLE CODE P0139

TECHNICAL SERVICE BULLETIN

Reference Number(s): 03-36-019, Date of Issue: August, 2003

HYUNDAI:	1999-2002 Sonata
GROUP:	36 - Engine Electrical

Superceded Bulletin(s): 02-36-037

NOTE: This TSB updates TSB 02-36-037, to include information on the correct reprogramming adaptor connector for 1999 & 2000 Model Year cars.

DESCRIPTION

This bulletin describes how to reprogram the ECM (Engine Control Module) in the 1999-2002 SONATA 2.4L I4 using the Hi-Scan Pro.

The SONATA I4 reprogramming affects the following:

Infrequent minor engine hesitation after an initial cold start (typically the first start in the morning).
DTC P0139 (O2 Sensor Circuit Slow Response (Bank 1, Sensor 2)) check engine light illumination diagnosis revised. If this code is set and the rear O2 sensor is diagnosed to be functioning normally, perform this ECM reprogramming procedure.

VEHICLES AFFECTED

Model: 1999-2002 Model Year (MY) SONATA with 2.4L DOHC engine
Affected vehicle production date range: Produced through July 7, 2002
Affected VIN range: Produced through KMHWF25S32A713157

ECM REPROGRAMMING PROCEDURE

CAUTIONS BEFORE REPROGRAMMING

Conduct reprogramming with the ignition key in the ON position.
Be careful not to disconnect the Hi-Scan Pro cables during reprogramming.
WARNING: If reprogramming is interrupted, the manual update procedure must be used.
Do not start the engine during reprogramming.
Do not turn the ignition key OFF during reprogramming.
When the reprogramming is completed, turn the ignition key OFF for 20 seconds before starting the engine.

AUTOMATED UPDATE PROCEDURE

NOTE: Verify that the vehicle is affected by identifying the vehicle production date and VIN.

Remove the Data Link Connector (DLC) cable from the Hi-Scan Pro and attach the Hi-Scan Reprogramming adapter (Fig 3 ).

Fig 3: Hi-Scan Pro and Accessories
On 2001 & 2002 MY cars, connect the RED 10-pin connector to the reprogramming adapter. On 1999 & 2000 MY cars, connect the RED 8-pin connector to the reprogramming adapter.
Remove the current software card from the Hi-Scan Pro and insert the reprogramming software card (32MB, Red label) into the Hi-Scan Pro top slot.
Insert the cigarette power adapter into the Hi-Scan Pro. (Fig 4 )

Fig 4: Power Adapter in the Hi-Scan Pro
Plug the power connector from the reprogramming adapter into the cigarette adapter.
Plug the power connector from the cigarette adapter into the Hi-Scan Pro. (Fig 5 )

Fig 5: Cigarette Adapter
Connect the RED 10-pin connector from the reprogramming adapter into the white connector near the Data Link Connector (DLC). On 1999 & 2000 MY vehicles, use the 8-pin RED connector. (Fig 6 )

Fig 6: Connected to 10-pin Connector

NOTE: Location of DLC is under the right side of instrument panel above driver's right foot. (Fig 7 )

Fig 7: DLC Location
Turn the ignition switch to the "ON" position.
Turn the Hi-Scan Pro ON and press ENTER.
Select option 25. EF 2.4D 99/00MY RR O2 SENSOR (P0139) or option 26. EF 2.4D 01/02MY RR O2 SENSOR (P0139) , depending on the vehicle by referring to the VIN and press ENTER. (Fig 8 )

Fig 8: VIN and Campaign Selection
Select option "[AUTO MODE]" and press ENTER (Fig 9 ). This option automatically detects the ECM type and downloads the correct program.

Fig 9: Select "Auto Mode"
Enter "1229" as the password for automatic update (Fig 10 ) and press ENTER.

Fig 10: Enter Password "1229"
The Hi-Scan Pro will establish communication and check the ECM ID. (Fig 11 , Fig 12 )

Fig 11: Establishing Communication

Fig 12: ECM ID Detection
The boot program will download first, then the main program and then the interrupt vector program. (Fig 13 )

Fig 13: Download Screen

NOTE: An error message may appear after the Boot Program is downloaded. The Hi-Scan Pro will automatically retry the download process. It is not necessary to do anything at this time. If the Hi-Scan Pro tries several times and does not download the program, go to Manual Update Procedure following this section.

WARNING: Do not interrupt the reprogramming at any time. The ECM will be rendered inoperative if the program does not download completely.
Hi-Scan Pro re-establishes communication (Fig 14 ).

Fig 14: Establishing Communication
When the "REPROGRAMMING COMPLETED" message is displayed, the ECM reprogramming process is complete. (Fig 15 )

Fig 15: Completion
NOTE:
- The new ECM ID is displayed when the new ECM software download process is finished.
- Before turning the Hi-Scan Pro OFF, check the new ECM ID displayed on the Hi-Scan Pro screen to verify that the correct ECM software has been downloaded. Refer to the "ECM SPECIFICATION" table shown in Fig 1 for the ECM ID listing.
Turn the Hi-Scan Pro OFF for 20 seconds and then start the engine to check for proper operation.
Check for DTC using the Hi-Scan Pro with system software card and erase any DTC.

MANUAL UPDATE PROCEDURE

NOTE:

In the event that "01. EF 2.4D 99/00MY [AUTO MODE]" or "01. EF 2.4D 01/02MY [AUTO MODE]" fails to download the new ECM program, option "02. EF 2.4D 99/00MY [ERROR MODE]" or "02. EF 2.4D 01/02MY [ERROR MODE]" must be used.
Confirm all connectors are established as shown in the "AUTOMATIC UPDATE PROCEDURE" before continuing.

Turn the ignition to the ON position.
Turn the Hi-Scan Pro ON and press ENTER.
Select option "25. EF 2.4D 99/00MY RR O2 SENSOR (P0139)" or option "26. EF 2.4D 01/02MY RR O2 SENSOR (P0139)" , depending on the vehicle and press ENTER. (See Fig 8 .)
Select option "02. [ERROR MODE]" and press ENTER. (Fig 16 )

Fig 16: Choose "[ERROR MODE]"
Choose the correct specification for your vehicle (Fig 17 ) by identifying the VIN and referring to the "ECM SPECIFICATION" table in Fig 1 .

Fig 17: Vehicle Specifications
Select the correct password for Manual Update from Fig 1 above. Enter the correct password (Fig 18 ) and press ENTER.
WARNING: If an incorrect password is used, the correct ECM software will not be downloaded.

Fig 18: Enter Appropriate Password
Wait until the reprogramming is completed. The Hi-Scan Pro will reprogram the ECM. (Fig 19 )
NOTE:
- Once the password is entered and accepted, the rest of the procedure is exactly the same as the automatic update procedure.
- An error message may appear after the Boot Program is downloaded. The Hi-Scan Pro will automatically retry the download process several times. It is not necessary to do anything at this time.
WARNING: Do not interrupt the reprogramming at any time. The ECM may be rendered inoperative if the program does not download completely.
