Update the software of the Thermal Management control unit (Address C5) with the software version
management (SVM) according to the following table. Observe the SVM unit code.

Note:
If the software of the address C5 Thermal Management is already at is at 0109 this bulletin does not
apply, further diagnosis is required.

Tip:
 ODIS tester: The ODIS tester patch version 2.2.3 and the baseline version 2.20.0 or higher must be installed.
 Make sure that a battery charger is connected 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
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.
NOTE:
During the software flash process, it is normal for the sound generator to output a loud continuous noise.
This sound will stop once the flash process is complete.

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.

NOTE:
After the software update an initial run of the compressor must be carried out according to the Guided
Functions. The start switch must be ON, brake pedal depressed and electric motor indicator in the
instrument panel in READY status (Figure 1). The initial run of the compressor will not complete without
READY status illuminated.
All other DTCs must be erased before performing the first run procedure.
