ECM REPROGRAMMING INSTRUCTIONS FOR P0139 & P0159 AND REPROGRAMMING FOR SMOOTHER FEELING INITIAL ACCELERATION

TECHNICAL SERVICE BULLETIN

Reference Number(s): 02-36-032-1, Date of Issue:  December, 2002
HYUNDAI: 2001 XG300; 2002 XG350
GROUP: 36 - Engine Electrical
Superceded Bulletin(s): 02-36-032
NOTE: This TSB supercedes 02-36-032. The ECM ID has been updated.

DESCRIPTION

(1) CHECK ENGINE LIGHT ON - DTC P0139 & P0159:

Some 2001-2002 XG300/350 vehicles may turn on the "Check Engine" light and have the diagnostic trouble codes P0139 and P0159 stored in the ECM.

These diagnostic trouble codes can be set incorrectly under certain driving conditions.

If the codes are set erroneously (the front O2 sensors function normally when diagnosed using the Hi-Scan Pro), perform the ECM software reprogramming procedure using the Hi-Scan Pro as outlined below.

(2) SMOOTHER FEELING ACCELERATION:

The initial acceleration characteristics of some 2002 XG350 vehicles may not feel as smooth as some customers desire.

A previous TSB and ECM reprogramming addressed this condition (TSB # 02-36-007 ECM REPROGRAMMING FOR SMOOTHER FEELING ACCELERATION).

This TSB and the accompanying ECM reprogramming makes an ADDITIONAL improvement above and beyond the previous TSB, as well as a correction for the CHECK ENGINE LIGHT ON - DTC P0139 & P0159 condition.

VEHICLES AFFECTED

CAUTIONS BEFORE REPROGRAMMING

  1. Conduct 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: If reprogramming is interrupted, the manual update procedure must be used.
  3. Do not start the engine during reprogramming.
  4. Do not turn the ignition key off during reprogramming.

ECM REPROGRAMMING PROCEDURE

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

AUTOMATIC UPDATE PROCEDURE

  1. Remove the current system software card from the Hi-Scan Pro and insert the reprogramming software card into the Hi-Scan Pro top slot.
    Fig 1: Hi-Scan Pro and Accessories
    G00314524
  2. Connect the reprogramming adapter to the Hi-Scan Pro.
  3. Connect the red 10-pin connector to the reprogramming adapter.
  4. Connect power to the Hi-Scan Pro from the cigarette power adapter.
  5. Insert the power cable from the reprogramming adapter into the cigarette power adapter.
  6. Connect the cigarette power adapter into the vehicle cigarette power socket.
    Fig 2: Connecting the Hi-Scan Pro
    G00314525
  7. Connect the red 10-pin connector from the reprogramming adapter into the white connector below and behind the Data Link Connector (DLC).

    Location: Under the instrument panel above the driver's right foot.

  8. Turn the ignition to the ON position.
  9. Turn the Hi-Scan Pro ON.
  10. Select option "24. XG300/350 REAR O2 SENSOR " and press ENTER.
    Fig 3: Selecting "XG300/500 REAR O2 SENSOR"
    G00314526
  11. Select option "01. XG300/350 REAR O2 SENSOR [AUTO] and press ENTER.
    Fig 4: Selecting "[Automatic]"
    G00314527
  12. Enter "1229" as the password and press ENTER.
    Fig 5: Entering Password
    G00314528
  13. The Hi-Scan Pro will establish communication, check the ECM ID, and reprogram the ECM automatically.

    G00314529
    Fig 7: Re-Programming ECM
    G00314530
    NOTE: The Hi-Scan Pro detects the current ECM ID and displays it for about 1 second.
    Fig 8: Hi-Scan Pro Displaying ECM ID
    G00314531
  14. The boot program will download first, then the main program and the interrupt vector program.
    Fig 9: Download Screen
    G00314532
    NOTE:
    • If the Hi-Scan Pro does not download the program properly, use the Manual Update Procedure following this section.
    • After the boot program download, it may go back to the chksum screen twice. This is considered normal during the reprogramming process.
      WARNING: Do not interrupt the reprogramming at any time. The ECM will be rendered inoperative if the program does not download completely.
  15. The Hi-Scan Pro establishes communication. See Fig 6 .
  16. When the REPROGRAMMING COMPLETED message is displayed, the ECM reprogramming process is complete.
    Fig 10: Re-Programming Completed
    G00314533
    NOTE:
    • The new ECM ID is displayed when the new ECM software download process is complete.
    • 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" above for the ECM ID listing.
  17. Turn the Hi-Scan Pro off and turn the ignition key to the off position for 10 seconds. Then start the engine to check for proper operation.

MANUAL UPDATE PROCEDURE

NOTE:
  • In the event menu option "01. XG300/350 REAR O2 SENSOR [AUTO]" fails to download the new ECM program, option "02. XG300/350 REAR O2 SENSOR [ERROR]" must be used.
