🔧 Proper diagnostics go beyond fault codes.

Today at JMP Performance we’ve been carrying out electrical diagnostics on this Citroën C4 Cactus, using our oscilloscope to check the LIN Bus communication signal.

The waveform on the scope allows us to see exactly what is happening on the network and confirm whether the LIN Bus signal is healthy and communicating correctly.

✅ Checking signal integrity
✅ Confirming LIN Bus communication
✅ Testing wiring and network operation
✅ Diagnosing the cause, not simply replacing parts

Modern vehicles rely heavily on communication networks between control modules, so sometimes a fault code is only the beginning of the story.

With our TOPDON diagnostic equipment and oscilloscope, we can dig much deeper and physically see what the vehicle's electrical system is doing.
