ECM SPECIFICATIONS:

REPROGRAMMING PROCEDURE:

CAUTION
Conduct reprogramming with the ignition key in the "ON" position. 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.

^ Do not start the engine during reprogramming.

^ Do not turn the ignition key OFF during reprogramming.

^ When the reprogramming is completed, turn OFF the ignition key for 20 seconds before starting the engine.

Notes:

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

To prepare for reprogramming in case of an error, write down the old and new ECM IDs displayed on the Hi-Scan Pro screen during the automatic update procedure.

The recorded ECM IDs will be used if the Hi-Scan Pro fails to automatically download the new ECM software.

AUTOMATIC UPDATE PROCEDURE:





1. Attach the Data Link Connector (DLC) cable to the Hi-Scan Pro main body and tighten the two (2) bolts securely.

2. Remove any software cards from the Hi-Scan Pro and insert the new reprogramming card into the Hi-Scan Pro top slot. Use the most current reprogramming software.





3. Connect the Hi-Scan Pro to the vehicle OBDII connector under the dash on the driver's side of the vehicle.





4. Turn the ignition to the ON position.

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

6. Select Option "18. MS 2.7 03/04MY Zr 02 SENSOR" and press ENTER.





7. Select Option "01. MS 2.7 03/04 MY Zr 02 SENSOR [AUTO]" and press ENTER.





8. Enter "0525" as the password for the automatic update mode and press ENTER.





9. The Hi-Scan Pro will reprogram the ECM automatically.

Notes:
The current ECM ID will be replaced by the new ECM ID.

If the Hi-Scan Pro does not download the program properly, use the manual update procedure following this section.

WARNING
Do not interrupt the reprogramming at any time. The ECM may be rendered inoperative if the reprogram does not download completely.





10. When the "REPROGRAMMING COMPLETED" message is displayed, 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 SPECIFICATIONS" in this TSB for the ECM ID listing. Turn the Hi-Scan Pro OFF and the process is complete.

11. When the reprogramming is completed successfully, turn the ignition switch to the OFF position for 20 seconds. Start the engine and check for proper engine operation.

12. Check for DTC using the Hi-Scan Pro with system software card and erase any DTC.

MANUAL UPDATE PROCEDURE:

Notes:

In the event menu Option "01. MS 2.7 03/04MY Zr 02 SENSOR [AUTO]" fails to download the new program, Option "02. MS 2.7 03/04MY Zr 02 SENSOR [ERROR]" must be used.

Confirm all connections are established as shown in the "AUTOMATIC UPDATE PROCEDURE" before continuing.





1. Turn the ignition to the ON position.

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

3. Select Option "18. MS 2.7 03/04MY Zr 02 SENSOR" and press ENTER.





4. Select Option "02. MS 2.7 03104MY Zr 02 SENSOR [ERROR]" and press ENTER.





5. Choose the correct vehicle year for your vehicle.








6. From the chart below, select and enter the correct password for the manual update mode, then press ENTER.





7. Wait until the reprogramming is completed. Hi-Scan Pro will reprogram the ECM manually.

Notes:
The program will take approximately 7 minutes to download completely.

The Hi-Scan Pro displays the new ECM ID on the screen.

WARNING
Do not interrupt the reprogramming at any time. The ECM may be rendered inoperative if the reprogram does not download completely.





8. When the "REPROGRAMMING COMPLETED" message is displayed, 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 SPECIFICATIONS on page 1 of this TSB for the ECM ID listing. Turn the Hi-Scan Pro OFF and the process is complete.

9. When the reprogramming is completed successfully, turn the ignition switch to the OFF position for 20 seconds. Start the engine and check for proper engine operation.

10. Check for DTC using the Hi-Scan Pro with system software card and erase any DTC.

TROUBLESHOOTING:

1. "INVALID PASSWORD" enter the correct password for the automatic update mode again (0525).

2. "REPROGRAMMING ERROR PLEASE WAIT FOR RETRY" an error occurred during reprogramming, the Hi-Scan Pro will retry the reprogramming automatically.

3. "THIS ECM IS DIFFERENT TYPE" the ECM on this vehicle is not the type subject to this reprogramming procedure.

4. "ALREADY REPROGRAMMED" the reprogramming has previously been done on this vehicle.

5. "REPROGRAM ERROR PLEASE CHECK SYSTEM" in this case, you must reprogram manually by selecting menu Option "02. MS 2.7 03/04MY Zr 02 SENSOR [ERROR]".
