REPAIR INFORMATION
NOTICE
•
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.
•
High temperature in the engine compartment might cause the VSA modulator-control unit to become too hot to run
the update. If the engine has been running before this procedure, open the hood and cool the engine compartment.
