SYMPTOM/CONDITION:
When the driver exits the vehicle, in some instances the Easy-Exit feature does not function. When the Ignition status is in transition from Run to Lock using the Keyless Go option, the Easy-Exit feature may be inhibited. Updated software for the MSMD will address this issue.

REPAIR PROCEDURE:
NOTE:
This flash will clear all existing memory positions. After the flash is completed, recall positions 1 & 2 will need to be reset.
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.

If this flash process is interrupted/aborted, the flash should be restarted.
CAUTION:
If this flash process is interrupted/aborted, and MSMD appears to be nonresponsive, red on the wiTECH ECU topology screen, cycle the ignition to lock and perform a battery reset. Ensure the battery remain disconnected for 20 seconds or more to allow for a full system shutdown. Once the battery is reconnected cycle the ignition to the run position and restart the flash.
