Production Solution
Implemented improved catalyst and improved software at Start of Production (SOP) MY20.

Service
Note:
It is mandatory that both the catalytic converter replacement and the ECM software update are performed
together!
Tip:
Always refer to ETKA for the latest part number information.
 Remove and replace the catalytic converter with part 3QF 254 500 MX, or part 3QF 253 059 PX,
before proceeding to the ECM software update below. Refer to repair manual group 26 Exhaust
System in Elsa.
Update-Programming Procedure:
Note:
Critical Warning: : The Midtronics battery charger must be connected to the vehicle battery for the
duration of the programming, to ensure the battery state of charge remains above 12.5 volts during the
update process. If the battery drops below 12.5 volts, the programming could fail which may result in
damage to the control module. Control modules damaged by inadequate voltage will not be covered
under the warranty policy. The technician should verify the vehicle voltage prior to starting the update
process, and should monitor the voltage for the duration of the update.
WARNING:
Radiator Fan(s) may cycle ON high speed during the Update Process! There is a 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!
Note:
Prior to launching the ODIS Service diagnostic applications and starting control module update process,
confirm tester screen saver and power settings in accordance with Diagnostic Device Hardware &
Windows® - VHW-20-02 Change Power Options After Windows®10 Upgrade. Failure to do so may result
in the tester entering power save mode during data transfer, and subsequent control module failure. When
using a VAS 6150/X or 6160/X tester in conjunction with a VAS 6154 wireless transmitter head for a flash
procedure, connect a USB cable between the transmitter head and the tester. Failure to do so may lead to
errors during the flash procedure.
VAS tools must only be used with their power adapters plugged in. Under no circumstances should they
be used on battery power alone during the programming procedure.

Tip:
To Update-Programming using Software Version Management (SVM), review and follow instructions in
Technical Bulletin Instance 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 or action is carried out that is not explicitly stated in the Technical Bulletin.
Note:
For MY18 Atlas vehicles: if the software update via SVM Unit Code is not successful, ensure that vehicle
update 23X1 (if applicable to this VIN) has been successfully completed, before performing the Engine
Control Module software update described in this technical bulletin.
 Update the Engine Control Module using the SVM Unit code as listed in the table below:
