Using tools like the software, a technician can read the EEPROM data from both the WSP and the ECU. The software "re-syncs" these files, which are then written back to the chips. This "marries" the units back together. 3. Immobilizer Bypass (Immo-Off)
There are several reasons why you may be experiencing the Error 13 Skacat issue on your Mercedes Sprinter or Vito. Some of the most common causes include:
If the hardware is fine, the data is likely corrupted. Technicians typically: Remove the WSP (Immobilizer) box and the ECU. mercedes sprinter vito start error 13 skacat
: The RFID chip embedded in the mechanical key loses its cryptographic pairing matrix.
: Technicians can install a physical electronic bypass board inside the engine bay. This emulator actively simulates the missing "handshake" authorization payload required by the engine computer during every key turn. Using tools like the software, a technician can
: A sudden surge from a jump start can sometimes scramble the modules' synchronized files. Key Issues
In Mercedes Sprinter/Vito (W638), the EDC ECU is usually located under the dashboard on the passenger side or under the hood near the cowl, often in a black plastic box. 2. Identify the EDC1 Plug (13-Pin Connector) Technicians typically: Remove the WSP (Immobilizer) box and

By carefully following the steps outlined in this guide, you'll be well on your way to clearing that dreaded "Start Error" and getting your Mercedes back on the road safely and reliably.
The software is designed to fix the synchronization issue between the ECU and the immobilizer. However, as noted above, this approach is not without risks. It requires reading the EEPROM data from the vehicle's modules with a programmer, running the software to correct the data, and then writing the corrected data back. Any mistake in this process can brick the ECU, leaving you with a much more serious problem.
If you are a DIY mechanic with diagnostic skills, here is the verified workflow to fix Error 13.
