INSPECTION PROCEDURE
Connect the i-HDS and check for DTCs.
* If DTC U3000-49, FCW/LDW Camera Unit Malfunction, is visible then clear the DTC and proceed to the Repair
Procedure and update the ACC/CMBS software.
+ If the DTC does not clear, continue with normal troubleshooting.
REPAIR PROCEDURE
+ 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.
