SOFTWARE UPDATE PROCEDURE
NOTE:
•

Make sure the 12-volt battery is fully charged before starting an update.

•

Connect a fully charged jumper battery to the vehicle, and leave it connected during the entire procedure to maintain
steady voltage.

•

Do not use the GR8 because the vehicle requires a steady electrical current.

•

Control module failure caused by the improper completion of a software update (early key cycle, low battery voltage,
disconnected DLC cable, etc.) is not covered by warranty.

•

If an error occurs during the update or the i-HDS freezes, do not disconnect the battery or turn the ignition to
OFF. Reboot the i-HDS, and start over.

•

To prevent control unit damage, do not operate anything electrical (headlights, audio system, brakes, A/C, power
windows, door locks, etc.) during the update.

•

Warranty reimbursement for technician labor is not allowed for routine checking/installation of any available
software update.

NOTE: This update will not require entering a service bulletin number.
