The ISM module with numbers A0002703252 / 0002703252 is used in Mercedes vehicles equipped with the 7G-Tronic Plus (722.9) automatic transmission. This type of control unit requires cloning and transferring the data from the old module in order to work correctly in the vehicle.
We offer an original ISM module with numbers A0002703252 / 0002703252, used in Mercedes-Benz vehicles equipped with the 7G-Tronic Plus automatic transmission, known as the 722.9 gearbox. The ISM (Intelligent Servo Module) is responsible for gear position control, communication with the TCU, and handling safety and start-authorization functions. It is an essential component for the correct operation of the transmission.
This ISM model does not exist in a VIRGIN version, therefore proper vehicle operation requires cloning / transferring data from the old module. Without this data the module will not synchronize with the vehicle and will not allow starting or shifting the 7G-Tronic Plus transmission.
The module was widely used in Mercedes-Benz vehicles from around 2011–2018 equipped with the 722.9 Plus transmission. Common applications include:
Because Mercedes used several ISM variants depending on year and transmission version, the only reliable method is comparing the number A0002703252 with the label on your module.
The ISM (Intelligent Servo Module) is an electronic actuator and control unit responsible for gear selection. It handles:
Each ISM stores unique vehicle-specific data (identification, TCU sync, immobilizer data). Therefore data transfer is mandatory — without cloning, the vehicle will not recognize the module and the transmission will remain inactive.
Q: Can ISM A0002703252 be installed as Plug & Play?
A: No. This module requires data cloning from the old ISM. Without it, the 722.9 transmission will not operate.
Q: If the part numbers match, can the module work without cloning?
A: No. Even with identical numbers, immobilizer and configuration data must be transferred.
Q: Can the ISM be coded using Launch/Autel?
A: In most cases, no. Coding is not enough — full memory cloning is required.
Q: Can I send my old module for cloning?
A: Yes. This is the most common and recommended solution.
Q: What if the old ISM is completely dead?
A: Sometimes the data is still recoverable. If the memory is fully unreadable, advanced deep programming tools are required.
Q: Does A0002703252 fit all 722.9 transmissions?
A: No. Mercedes used several versions, so always compare A0002703252 / 0002703252 with your original module.
