Mercedes ISM Coding

Masters at ISM Coding

Is your Mercedes Benz displaying an error message “Drive to the workshop without changing gear” Then you have a faulty ISM. Other symptoms include car not shifting gears between P, R, N, or D. ISM in full Intelligent Servo Module’s main purpose is that it enables the system to read the selected drive position via electrical signals and to engage the drive position via a mechanical interface on the transmission. The Mercedes ISM system is located on the driver’s side on the transmission housing.

If the ISM is malfunctioning, it can cause a variety of problems, such as:

  • Difficulty shifting gears
  • Erratic steering
  • Check engine light

If you are experiencing any of the above-listed issues with your car, Carkey Masters specializes in resolving these issues through expert ISM reflashing and programming services.

What to do

In case it happens, don’t change gears when driving, as this will cause the car to instantly come to a halt given the main issue the ISM causes as we mentioned is difficulty changing gears. In the event that you can’t come to us, we offer mobile services and can send one of our technicians to your location.

At Carkey Masters, we not only have the right personnel to handle any Mercedes Benz related problems but we also have the right equipment that is the Mercedes All System scanner in our Mercedes ISM coding kit that we use to first run a diagnosis on your ISM before taking any further steps.

Solution

  • ISM Reflashing: If your ISM’s software is outdated or corrupted, we can reflash it with the latest, error-free software to restore its functionality. This process involves updating the module’s internal code using specialized tools and software.
  • ISM Coding (New or Replacement): If your ISM is damaged beyond repair, or you’re upgrading to a newer model, we can source and install a new or used (donor) ISM unit. We then perform expert coding to match the new module to your specific Mercedes model, ensuring seamless communication with other systems in your car.
