Personalization Without Previously Saved FBS4 Data from the Original Module Coming for the Latest CRD3 MFA ECU Software Versions

The next ABRITES software update will expand support for CRD3 MFA ECUs, used in Mercedes-Benz vehicles adding personalization for the latest software versions without previously saved FBS4 data from the original module.

What’s New?

With MN034 DAS4/FBS4 Personalization Expert, technicians will be able to perform:

• Setting a replacement ECU to virgin state
• Personalization without previously saved FBS4 data from the original ECU
• Adaptation of the replacement ECU

This is particularly useful when the original ECU is damaged, inaccessible or its FBS4 data cannot be retrieved.
Personalization when FBS4 data from the original module is available can be done using the DAS Manager for FBS4 cars license (MN032).

Supported Mercedes-Benz Applications

CRD3 MFA ECUs can be found in Mercedes-Benz diesel applications including:

• Mercedes-Benz A-Class W176
• Mercedes-Benz A-Class W177
• Mercedes-Benz B-Class W246
• Mercedes-Benz W156

Replace the ECU with a Second-Hand Unit

One of the biggest advantages of this functionality is the possibility to use a compatible second-hand ECU as a replacement, even when previously saved FBS4 data from the original module is not available.
For the technician, this means a faster and more cost-effective repair, with greater flexibility when sourcing replacement modules.
The customer benefits too: using a compatible second-hand ECU can significantly reduce the cost of the replacement compared with purchasing a new control unit, while the more efficient workshop procedure can save valuable service time.
With the upcoming CRD3 MFA expansion, MN034 gives Mercedes-Benz specialists a practical solution for more ECU replacement scenarios while helping both workshops and their customers save time and money.
