: Check the physical switch on your K+DCAN cable. If your car is pre-2007, you may need to bridge pins 7 and 8 on the cable connector. For post-2007 cars, these pins must be separated.

If you own an adjustable cable, slide the manual toggle switch to the opposite side and attempt re-entry. Step 4: Refresh Outdated SP-DATEN Binary Files

INPA and the interface must know whether the ignition is ON (Terminal 15) or OFF. Some aftermarket USB cables have poor ignition sense circuits. When you select a job (e.g., reading DME error memory), the ECU expects terminal 15. If it senses ground instead, it returns an "incorrect result."

The software does not "see" that the car is on. Many cheap K+DCAN cables lack a bridge between pins 7 and 8, or the "Battery" and "Ignition" dots in INPA remain white (off) even when connected.

The market is flooded with cheap, poorly soldered K+DCAN cables. White-board cables or clones missing the genuine FTDI microchip frequently overheat or drop data packets, causing intermittent communication timeouts. Investing in a high-quality, green-board cable with an integrated switch can save hours of software troubleshooting. Summary Checklist Select Properties > Port Settings > Advanced

These models require Pin 7 and Pin 8 to be physically bridged together inside the cable plug to read both engine and chassis networks.
