Inpa Error 159 -

Deep dive: INPA error 159

Summary

• Error 159 in INPA typically means a CAN-bus communication fault between the control module and the diagnostic tool or between modules. It’s often logged as "Control module not responding" or "No communication (159)" in BMW INPA/EDIABAS contexts.

Software Configuration: Errors in the EDIABAS.ini file, such as an incorrect interface setting (e.g., set to STD:ADS instead of STD:OBD), will block the connection. Troubleshooting Checklist

The Hardware Hiccup: A common cause is a poorly connected or incompatible interface, such as a VXDIAG VCX SE device that isn't properly seated or configured. inpa error 159

Q: I set latency to 1ms, but Windows resets it to 16ms. Why? A: Some counterfeit chips ignore latency settings. You need to use the FTDI Prog tool to write the latency value directly to the EEPROM of the cable. Or buy a better cable. Deep dive: INPA error 159 Summary

Several factors can contribute to this error: Error 159 in INPA typically means a CAN-bus

2. Use a Native Serial Interface

USB introduces latency and voltage issues. If you have an older laptop with a physical RS-232 port, buy a native RS-232 to K-Line interface (e.g., ADS interface). These do not buffer data, so Error 159 never appears on K-Line vehicles.

: The most frequent cause is a physical connection issue between your OBDII cable (K+DCAN) and the car, or between the cable and your computer's USB port. Driver/COM Port Settings
