# Service bulletin LI54.10\-P\-080881

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Complaint AC and DC charging are not possible. The white LED on the charging inlet completely goes OFF after plugging in the charging cable. Related DTCs in quick test: There are no related fault codes \(DTCs\) stored in relevant control units. CPC3 \- N127 \(Drivetrain control unit\) OBL223\_GEN4 \- N83/11 \(Alternating current charger for high\-voltage battery\) DCB223 \- N116/5 \- Direct current charge connection unit \(DCCU\) Cause Control pilot \(CP\) circuit in DCB \(N116/5: Direct current charge connection unit\) might be not functional due to electrical overstress from EVSE \(Electric Vehicle Supply Equipment \| Charging Station\). Remedy Refer to the charging cable actual values in DCB \(N116/5\). The actual value “Charging cable at charging station” and “status of pilot function” shows “Charging cable NOT PLUGGED IN” \& “CP not connected” respectively, even though the charging cable is connected on both sides. This confirms a possible breakdown of Control Pilot \(CP\) circuit inside the DCB. Measurement of the resistance of Proximity Pilot \(PP\) and Control Pilot \(CP\) at the charging socket \(G10\) \(see Annex “Resistance measurement Proximity Pilot \(CP\) and Control Pilot \(CP\)”\)
