Key Programming With Delphi Ds150e | Reliable - 2025 |

| Problem | Likely Cause | Solution | |---------|--------------|----------| | CAN errors on high-speed vehicles (e.g., BMW) | Bus load too high due to inefficient polling | Implement sleep(10) between request loops; use CAN filtering | | K-line no response | Missing pull-up resistor on OBD pin 7 | DS150E hardware: check R32 (1kΩ) on PCB. In software: enable KLINE_5V_PULLUP flag | | Scripts not executing | Security restrictions in Delphi 2016+ | Set HKLM\Software\Delphi\DS150E\Scripting\Enabled = 1 | | USB disconnects under heavy load | FTDI chip overheating | Replace electrolytic capacitor C19 (100µF) on DS150E board |
