REPAIR PROCEDURE:
NOTE:
Install a battery charger to ensure battery voltage does not drop below 13.2 volts. Do not allow the charging voltage to climb above 13.5 volts during the flash process.
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted.

For instructions select the "HELP" tab on upper portion of the wiTECH window, then "HELP CONTENTS." This will open the Welcome to wiTECH Help screen where help topics can be selected.
3. Is the vehicle equipped with PWR Front Windows, 1-Touch Up & Down (sales code JP3) or PWR Windows Front, 1-Touch Down (sales code JPY)?
a. Yes >>> reprogram the DDM, proceed to Step # 4.

5. **Turn off the vehicle and let the Communication Buss go to sleep, this may take over a minute before the Buss goes to sleep. This will cause all active DTC to go stored.

NOTE:
After the update has been completed the vehicle may have switched out of customer mode and goes into Abbreviated Mode. This will cause the power door lock not to operate after the vehicle goes to sleep.
