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 proxy configuration process.

1. Using wiTECH, restore vehicle configuration. This routine is available under the ’Guided
Diagnostics’ tab found on the home, ’Vehicle View’ page of wiTECH.
2. Perform vehicle bus system sleep session. Turn off the vehicle, unplug the wiTECH and open and
close the driver door. Let all modules go to sleep (this should take approximately one minute).
3. Reconnect wiTECH and clear any DTCs which may have been set during the reconfiguration
procedure.
4. Clear all DTCs that may have been set in any module due to reconfigure. The wiTECH application
will automatically present all DTCs and allow them to be cleared.
