P0D22 Battery Charger A Output Current Performance

P0D22 means the on-board charger does not deliver the high-voltage current it was asked for. GM's Volt compares actual and desired current in constant-current mode against a table: 150 of 300 samples set it in 2011, One Trip Type A; from 2014 a second part also catches a charger that was switched on, with more than 201 V commanded, but never enabled its output after 6 s. Mitsubishi's Outlander PHEV stops charging when target and actual differ by 3 A or more for 3 s. GM bulletins cite P0D22 with MIL and no charge on the 2011 and 2013 Volt (HPCM2 updates) and, in PIP6048, on the Lyriq, Optiq, Blazer EV and Equinox EV during level 2 charging, where reprogramming the BECM comes first. Voltage deviations belong to P0D20/P0D21, a shorted output to P0D23.

Likely causes

Charge control software in the hybrid or battery control module (GM PIP bulletins)
Internal fault in the on-board charger
Faulty output current measurement

Symptoms

  • Vehicle does not charge or charging stops
  • MIL on after a charge session ends
  • Problem shows mainly on AC level 2 stations
