The connection board for advanced IMMO bench work.
The X-PROG3-MCU3 PCA Board is an accessory for a compatible IMMO programmer. It provides the connection path required by selected bench procedures for control units and immobiliser components. The board does not read keys, clone ECUs or activate software on its own: those operations depend on the programmer, licensed functions, vehicle and correct connection diagram.
At a glance
Accessory, not a scanner
Used alongside the supported programming hardware and software, not as a standalone diagnostic device.
Bench connection
Provides an adapter interface for specified off-vehicle ECU/TCU and immobiliser procedures.
Clear identity
SmartSafe dealer catalogue article 605010056; confirm the exact board revision and connector set on the delivered part.
Functions in the workshop
What the board does
It adapts the programmer’s connection for supported MCU and module work. The programming device supplies the control interface; the vehicle-specific application determines pinout, power and any resistor or supplementary lead.
Typical bench tasks
The referenced X-PROG3 workflow describes ECU/TCU read or clone procedures and certain key/immobiliser cases. This is a description of the supported system context, not a claim that every task works with this accessory alone.
Power and connection
Follow the wiring diagram for the selected module. The reference material shows examples involving a 120 Ω termination or a 12 V supply, but they are alternatives for particular bench arrangements, not universal instructions.
Mercedes-Benz examples
The counterpart documentation discusses selected all-keys-lost workflows with compatible programming systems. Coverage depends on model, year, firmware, authorisation, cable set and licensed function.
Before first use
Match the board revision to the SmartSafe programmer and the software menu. Verify the pin assignment and power before connecting an ECU, TCU, key or immobiliser module.
Scope of delivery
This listing refers to the MCU3 adapter board. A programmer, diagnostic tablet, vehicle-specific cables and activation are separate unless expressly included in the commercial offer.
Suggested workflow
- Identify the controller and exact supported function in the SmartSafe programmer’s current software.
- Check MCU3 board revision, cables, pinout, power and any specified termination in the service diagram.
- Connect only with power off, then run the guided bench operation on the compatible programmer.
- Verify the saved data and module behaviour according to the vehicle manufacturer’s procedure.

Before ordering and use
Compatibility of this specific SmartSafe article with IMMO G3 and each desired vehicle/function must be confirmed from the current SmartSafe coverage and the supplied board revision. Third-party examples describe a related X-PROG3 system; they do not establish that LAUNCH and SmartSafe boards or software are interchangeable.
