Original publication.

One of the following conditions is present after the vehicle was left plugged-in to an AC charging station
for an extended period of time after charging has finished:
 The vehicle cannot be started (“Ready” mode cannot be established).
 The 12 Volt battery is dead, or the vehicle requires a jump-start.
 The vehicle and/or charge socket cannot be unlocked using the remote control key.

Technical Background
Software-related deviation in the High-Voltage Battery Charging Voltage Control Module -J966-.

Production Solution
Optimized software in the High-Voltage Battery Charging Voltage Control Module -J966-.

Service
Step 1: Update Software of the High-Voltage Battery Charging Voltage Control Module -J966Note:
Prior to launching the ODIS service diagnostic applications and starting control module update process,
confirm Date/Time & Time Zone.
The Windows date/time and time zone settings are used by the diagnostic software as a component of the
diagnostic logs submitted for warranty purposes. If the date/time and time zone are incorrect on submitted
diagnostic logs, warranty claim reimbursement may be questioned and/or delayed.
Ensure date/time etc. settings are correct as follows:
1. From the Windows desktop toolbar, double click on the local time indicator (typically found in the lower
right corner of the desktop).
2. Use the tabs to ensure the current date/time, and time zone applicable to your location is set correctly.

Tip:
To Update-Programming using SVM, review and follow instructions in Technical Bulletin 2014603
“Software Version Management”.
The SVM Process must be completed in its entirety so the database receives the update confirmation
response. A warranty claim may not be reimbursed if there is no confirmation response to support the
claim.
 ODIS tester: The ODIS tester patch version 5.1.6 and the baseline version 2.39.13 or higher must be
installed.
 Connect a GRX3000VAS or MTRMSP0702 battery maintainer/charger to the vehicle battery.
 Make sure that during the software update no electro-magnetic radiation sources (for example, mobile
phones or cordless phones) are used in or near the vehicle.
 A cable connection between the ODIS tester and the vehicle must be used. When using a Bluetooth or
WIFI connection (diagnostic tool) the software update may fail.
 During the software update switch the hazard warning lights on to ensure a constant CAN data bus
activity of the vehicle.
Note:
The vehicle must not be connected to a High Voltage charger during this update.
Using software version management (SVM), update the software of the charge manager module
(diagnostic address BD).
 To perform the software update, after the full vehicle scan, click on the “Special Functions” tab and
select “Adapting Software”.
 Follow the on screen prompts using the SVM unit code as listed in the table below.
Note:
This update is only applicable to the specific part numbers and software levels listed in the table below. If
the SW level is already at the highest version shown this bulletin does not apply.
