Bulletin No.: 01-030/08Last Issued: 06/23/08
Subject:
PRECAUTIONS FOR MODULE REPROGRAMMING
APPLICABLE MODEL(S)/VINs
DESCRIPTION
This Service Bulletin provides precautions for module reprogramming and actions to take when problems occur during reprogramming.
ACTIONS RECOMMENDED
1. Preparation for Reprogramming.
a. Perform regular maintenance of the PC to keep it stable. You should defrag the hard disc drive (HDD) [relocate the the split files (fragmentation) to sequential files] of the laptop PC unless it has been defragged regularly. To defrag the computer:
NOTE:
Close all other applications before defragging and DO NOT operate, resume, or turn (shut) off the PC while defragging.
- Select "Start," "Accessories," "System Tools," then "Disk Defragmenter." The Disk Defrag screen appears.
- Select "C drive," then click "Analyze."
^ When defrag is necessary, a message appears on the screen - click "Defragment."
^ When defrag is not necessary, a message appears on the screen - click "Close."
b. Do not run other applications.
c. Use the A/C power adaptor for the laptop PC (IDS). For the pocket PC (PDS), make sure the battery is fully charge in advance.
d. Make sure the vehicle side connector and the DLC cable are firmly connected. DO NOT touch the DLC cable anymore after verifying this.
e. Connect a battery charger to the vehicle. Only start reprogramming after making sure the battery voltage is normal.
f. Save the session when the vehicle identification is done. This way, if reprogramming fails, you may resume the reprogramming session from the saved session.
g. Perform the self-test and verify no CMDTCs are detected before or after reprogramming single or multiple modules.
2. Handling problems during reprogramming.
a. Symptom 1: During reprogramming, the screen suddenly returns to the initial screen, then reprogramming stops and cannot continue.
- Make sure the VCM mark appears on the IDS screen. If it does not appear on the screen, check the DLC connection for poor connection.
- Check the battery voltage to see if it is normal. If the battery voltage is low, check the booster cable for poor connection.
- Confirm the error message on the IDS screen. If you continue the session, the message "Do you wish to retry?" appears. Click "Yes."
- After reprogramming again, make sure the session has finished without fail.
^ If the session failed, perform reprogramming another 3-5 times.
^ If the session keeps failing no matter how many times you have tried, delete the session and close it.
- Open the session which was saved before reprogramming and start another session.
b. Symptom 2: PC screen freezes while reprogramming.
- Press the "Start" button in the lower left hand corner to see if the menu screen appears.
^ If the menu screen appears, the IDS has frozen.
^ If the menu screen does not appears, the PC has frozen.
- If the IDS has frozen:
1. Press "Crtl," "Alt," "Delete" keys at the same time to open Windows Task Manager.
2. Choose End Task to finish IDS.
3. Reboot the IDS and perform the vehicle identification again, then start another reprogramming session.
- If the PC has frozen:
1. Press "Crtl," "Alt," "Delete" keys at the same time to open Windows Task Manager.
2. Choose End Task to finish IDS. If there is no response, then press "Esc" several times. If there is still no response, press the power button for several seconds to shut down the PC.
3. Reboot the IDS and perform the vehicle identification again, then start another reprogramming session. If the vehicle identification cannot be performed, open the session that was saved before reprogramming, then start another reprogramming session.
