Service
Procedure:
Update the software of the thermal management control unit (diagnosis address C5) with the software version
management (SVM) according to the following table. Observe the action code.
Note:
If the software is already at 0108 this bulletin does not apply, further diagnosis is required.
Tip:
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.
Note:
Prior to launching ODIS application and starting control module update process, confirm tester screen
saver and power settings in accordance with Special Tools and Equipment - Service Information Circular
# VVT-12-02. Failure to do so may result in the tester entering power save mode during data transfer, and
subsequent control module failure.
• To perform the software update, after the full vehicle scan, click on the “Special Functions” tab and then select
“Adapting Software”.
• Follow the on screen prompts to update the Thermal Management Control Unit using the SVM Unit code as
listed in the tables below:

Technical Bulletin
• 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
connection (diagnostic tool) the software update may fail.
• A cable connection between the ODIS tester and your workshop network must be used. When using a 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.
The SVM flash procedure can be found in GFF under Functions/ Component Selection, Software Version
Management, Adapting Software.
WARNING:
Radiator Fan(s) may cycle ON high speed during the update process! There is a serious risk that personal
injury may result if contact is made with spinning fan blades. Keep hands and all objects away from
Radiator Fan(s) during Update Process!
• After the update is complete check and erase all DTCs.
Tip:
After the software update an initial run of the compressor must be carried out according to the Guided Functions.
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 or action is carried
out that is not explicitly stated in the Technical Bulletin.
