Choosing the ISM module – A0002701652 and A2C53353106
A used, original ISM module (Siemens VDO) working with the 7G-Tronic 722.9 gearbox. This is the VIRGIN version – clean and reset, ready for programming. The bench test is done before every dispatch.
How does an ISM module failure show up?
- the gearbox goes into limp mode,
- the gearbox does not respond when D or R is selected,
- gearbox fault message.
Before you order, run a diagnosis – the selector, wiring and the gearbox control unit (VGS) can behave in a similar way.
Have a different number?
Check the other ISM modules we offer: A0002701752, A1644460310, A1644460410, A0044460310. Always compare the number on the label.
Compatibility with the car
We do not list models because we have not confirmed them for this number – this is an ISM module for the 7G-Tronic 722.9 gearbox in Mercedes-Benz cars. What matters are the codes on the label of your module: A0002701652 and A2C53353106. In the Mercedes-Benz catalogue, number A0002701652 is superseded by A0002701852 – we stock that module too: A0002701852.
How to put the module into service
First the positioner (selector) must be calibrated, and only then the ISM module adapted to the gearbox and the car. You can also ask us to clone the data from the old module – included in the price.
