P2D34Hybrid/EV Battery Inductive Charger Control Circuit Range/Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- P2D34 points at the control line of the inductive charger, the wired path over which a vehicle controller wakes, enables or commands the charger module. The circuit is not open or shorted, but its level or duty cycle lies outside the expected window or does not follow the command. No manufacturer documents P2D34 publicly, and which signal the line carries depends on the design. Wireless systems need such coordination because the vehicle side sets how much power it takes: the Magne Charge paddle used an infrared link to report the demand of the on-board charge controller, and a Hyundai patent (US10245962B2) has the vehicle assembly controller read coil current and battery data before it drives its active rectifier. CARB requires charger faults that block or slow charging to be found. Check connectors, ground and software first.
- What you may notice
- Inductive charging is not offered or ends without a clear reason
- Charging works intermittently depending on vibration or temperature
- Likely causes
- LikelyCorroded or loose connector raising the resistance of the control line
- PossibleSoftware levels of charger module and commanding controller that do not match
- RareFaulty output or input stage in one of the two modules
- Repair
- Hard · Usually a job for a workshop.Typical cost: €80 – €1,500
