UPDATING TIPS AND PRECAUTIONS
^ If you're updating a control module/unit on a new vehicle, make sure all its fuses were installed at TQI.
^ To prevent control unit/module damage, do not operate anything electrical (audio system, brakes, A/C, power windows, moonroof, etc.) during
the update.
^ If the Database Update listed in the service bulletin is later than that shown by the software, please see the software installation procedure in the
following two documents in Tool Information on ISIS (go to General Publication, then Tool Information):
^ Installation Instructions for HDS PC Software
^ MVCI User Guide (see HDS MVCI Firmware Update section)
^ Do not connect an additional power supply to the MVCI when it is connected to the vehicle; power is supplied through the DLC.
^ To ensure that the control module/unit is not permanently damaged during updating, verify that the vehicles 12-volt battery is fully charged
206
before starting an update.
NOTE:
If the vehicles 12-volt battery drops below 10 volts during the update, the programming status bar may go past 100 percent, or the updating
tool may display an error message.
^ If you have a problem during an update (D4/immobilizer indicator flashes, update tool freezes, etc.), you can minimize the chances of damaging
the control unit/module by doing one or more of these actions:
- CRITICAL: Keep the ignition switch in ON (II).
- Connect a jumper battery (DO NOT connect a battery charger).
- Disconnect the updating tool from the vehicles DLC.
- Reboot the updating tool.
- Reconnect the updating tool to the vehicles DLC, and retry the updating procedure.
HOW TO CHECK IF THE MVCI IS UPDATED
Whenever there is an HDS software update, there will
be an update for the MVCI. After updating the HDS,
update the MVCI. For more information on how to
update the MVCI, refer to the Modular Vehicle
Communication Interface (MVCI) User Guide on ISIS
under General Publications > Tool Information.
To check that the MVCI has the latest database
installed, go to the iN home page and click on
SERVICE > Service Bay > Diagnostic Tools
Software Versions. The most recent version of the
database is listed under CM Update database.
Turn on the MVCI, then press the ENTER button on the
MVCI to see the User Config menu. Select CM Update
Mode, then select Reprogramming.
The current database update version is listed under
Database Update.
If the Database Update version is not the same as the
most recent version listed on ISIS, update the MVCI.
Unnecessary or incorrect repairs resulting from a
failure to update the HDS or MVCI are not covered
under warranty.
