Faulty active discharge circuit or failing internal components in the on-board charger; Charger control unit software fault or outdated calibration (model dependent); Wiring or connector fault on the charger's high-voltage or low-voltage control circuits; Low or unstable 12 V supply upsetting charger or contactor control; High-voltage contactor sticking or slow to open, or a fault in the voltage sensing; Fault in the high-voltage battery management or the DC-DC converter sharing the high-voltage bus.

D: AreaReserved
5E: FaultThe specific fault in that area

What it means

P0D5E means the control unit monitoring the on-board battery charger in a hybrid or electric vehicle saw the charger's internal high-voltage circuit take too long to discharge to a safe level. This normally follows the end of a charge session or the opening of the high-voltage contactors. The exact voltage threshold and time limit depend on the manufacturer and model.

Symptoms

Warning light on, possibly with a hybrid or EV system message
Vehicle will not charge or stops charging early
Charge port lock or charging connector may not release as expected
Reduced power or the car refusing to enter ready mode on some models
Fault appears after a charge session or when switching the car off

Possible causes

Faulty active discharge circuit or failing internal components in the on-board chargerlikely
Charger control unit software fault or outdated calibration (model dependent)possible
Wiring or connector fault on the charger's high-voltage or low-voltage control circuitspossible
Low or unstable 12 V supply upsetting charger or contactor controlpossible
High-voltage contactor sticking or slow to open, or a fault in the voltage sensingpossible
Fault in the high-voltage battery management or the DC-DC converter sharing the high-voltage busrare

How to diagnose

Read all stored and pending codes and note any related charger, contactor, isolation or 12 V codes
Review freeze frame data and note when the fault set, for example at the end of a charge or at shutdown
Check the 12 V battery condition and charging voltage, as low voltage can cause spurious charger faults
Visually inspect the charge port, the charger's connectors and the low-voltage wiring for damage, corrosion, water ingress or heat marks
Check for manufacturer service bulletins and software updates for the charger control unit on this model
Using live data, compare the charger's reported bus voltage with the battery voltage after charging stops and check how quickly it falls
Have a qualified high-voltage technician isolate the system and test the charger, contactors and high-voltage wiring following the manufacturer's procedure
Clear the code and retest with a full charge cycle to see if it returns

How to fix

Repair or replace damaged wiring or connectors in the charger control circuits
Restore the 12 V supply by charging or replacing a weak battery
Update the charger control software where an updated calibration is a known fix for this model
Replace the on-board charger if its discharge circuit or internal components are confirmed faulty
Replace a faulty high-voltage contactor or voltage sensor if testing confirms it
Retest through a full charge and drive cycle to confirm the code does not return

Can I keep driving?

Medium severity

The car may still drive, but charging may be limited or stopped, and some models reduce power. Get it checked soon, and stop driving if a red high-voltage warning appears or the car loses power. Only qualified technicians should work on high-voltage components.
