Fault or reduced output in the on-board charger unit; Poor supply from the charging point, cable or home supply, such as voltage drop or limited current; Damaged, corroded or loose connections in the charge port, charger or high-voltage wiring; High-voltage battery fault or battery management limiting the accepted charge power, for example due to extreme temperature or cell imbalance; Charger cooling fault causing the unit to reduce power through overheating; Outdated or faulty control unit software or calibration, where the manufacturer has issued an update; Internal fault in the charger current or voltage sensing.

What it means

P0D5C is a generic powertrain code meaning the on-board battery charger's output power performance is not as expected. The charger control unit compared the power it delivered to the high-voltage battery with the power it was commanded to deliver and found a mismatch, or it could not reach the requested level. The exact thresholds and monitoring strategy vary by manufacturer and model.

Symptoms

Charging is slower than normal or stops before the battery is full
Charge fault or service warning shown on the dashboard
Charging session fails to start or ends early
Reduced indicated range after charging
Malfunction indicator or EV system warning lamp on

Possible causes

Fault or reduced output in the on-board charger unitlikely
Poor supply from the charging point, cable or home supply, such as voltage drop or limited currentlikely
Damaged, corroded or loose connections in the charge port, charger or high-voltage wiringpossible
High-voltage battery fault or battery management limiting the accepted charge power, for example due to extreme temperature or cell imbalancepossible
Charger cooling fault causing the unit to reduce power through overheatingpossible
Outdated or faulty control unit software or calibration, where the manufacturer has issued an updaterare
Internal fault in the charger current or voltage sensingrare

How to diagnose

Read all stored codes and freeze frame data, noting battery temperature, state of charge and supply conditions when the code set, and check for related battery or charger codes
Try charging from a different known-good charging point and cable to rule out the supply or equipment
Inspect the charge port, pins, seals and cable for damage, moisture, corrosion or heat marks
Check the 12 V battery condition and the supply voltage to the charger control unit, as low voltage can cause performance faults
Check the charger cooling system, including coolant level, pump operation and airflow where fitted, following the manufacturer's procedure
Use live data to compare commanded and actual charger output voltage, current and power during a charge
Check the high-voltage battery data for temperature limits, cell imbalance or restricted charge acceptance
Check for applicable software updates or technical bulletins for the specific model, and only work on high-voltage components if trained and following isolation procedures

How to fix

Repair or replace damaged charge port components or wiring
Resolve supply issues by repairing the charging equipment or home supply
Restore cooling function by topping up coolant, bleeding the system or repairing the pump or hoses
Replace the on-board charger if testing confirms it cannot deliver the commanded output
Address the high-voltage battery fault found by diagnosis, as the model requires
Update the control unit software where an outdated calibration is confirmed as the cause

Can I keep driving?

Medium severity

The car can usually still be driven if it has enough charge, but the fault may reduce charging ability and leave you short of range. Have it diagnosed soon, and stop driving if a high-voltage or battery warning appears.
