Possible Causes
Faulty PLC modem on Andersen main control PCB, Electrical noise on line conductors, EV onboard charger communication fault, Damaged Type 2 cable affecting PLC signal
How to Fix / Troubleshooting
Safety first: PLC is a low‑voltage communication over the power lines; treat the charger as live until isolated.
User steps:
- Unplug the EV and inspect the Type 2 plug and socket for damage or contamination.
- Power cycle the charger and the EV (lock/unlock car, or follow vehicle reboot procedure).
- Try a different Type 2 cable if available.
- Test with another EV if possible to determine if the issue is vehicle‑specific.
If E19 occurs with multiple vehicles and cables:
- The PLC modem or associated circuitry in the Andersen charger may be faulty.
- A technician should test the PLC module on the main control PCB and replace the PCB if necessary.
