What does P325A mean?
P-code P325A means "Inverter CAN Communication Error". It is a manufacturer-specific diagnostic trouble code (DTC) in the vehicle network (CAN/LIN bus). A communication failure has been detected — the module responsible for the inverter can communication error is not responding on the vehicle network. This warning should be addressed within the next few days to avoid further damage. This code applies to OBD-II compliant electric and hybrid vehicles.
Possible Causes
- CAN bus wiring fault (short, open, or termination resistor failure)
- Faulty control module not transmitting on the vehicle network
- Power supply issue preventing the module from initializing
- Software mismatch or corruption in the affected module
Recommended Actions
- 1 Avoid aggressive driving and schedule a diagnostic appointment within the next 1–3 days
- 2 Scan for all DTCs with an OBD-II scanner — note any related codes stored alongside P325A
- 3 Check CAN bus wiring for damage; verify termination resistance (should be ~120 Ω between CAN-H and CAN-L)
- 4 Verify power supply and ground connections at the affected module
- 5 Clear the DTC, road-test the vehicle, and re-scan to confirm whether the fault returns
- 6 If the fault persists after inspection and clearing, consult an EV-certified technician for component replacement
