Automatic Update Procedure





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

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





3. Plug the DLC cable from the Hi-Scan Pro into the data link connector (16-pin connector) to the left of the steering wheel under the instrument panel.





4. Turn the ignition to the ON position.

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

6. Select option "31. LC 00~02MYCOLD STUMBLE&02MY P0116" and press ENTER.

7. Select option "01. LC 00~O2MYCOLD STUMBLE [AUTO]" and press ENTER.

This option automatically detects the ECM type and downloads the correct program.





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

9. The Hi-Scan Pro will establish communication and check the ECM ID. The Hi-Scan Pro will reprogram the BCM automatically.





NOTE

^ The Hi-Scan Pro detects the current ECM ID, assigns the new ECM ID and displays them for a short time.

^ To be prepared in case a reprogramming error occurs, write down the "NEW ECM ID" displayed on the Hi-Scan Pro screen during reprogramming.

^ It will be used during the Manual Update Procedure if the program does not download correctly.

^ If the Hi-Scan Pro does not download the program, use the Manual Update Procedure following this section.





^ Check the ECM IDs displayed on the Hi-Scan Pro screen to verify that the correct ECM software is being downloaded. Refer to the "ECM SPECIFICATION TABLE" on in this bulletin for the ECM ID listing.

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





10. When the COMPLETED message is displayed, turn the Hi-Scan Pro OFF and the process is complete.

NOTE
When reprogramming has been completed successfully, turn the ignition to the OFF position for 20 seconds and then start the engine to check for proper operation.
