P2E32 Battery Charger A Module Forced Shutdown Voltage Performance

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

P2E32 belongs to the forced shutdown input of on-board charger A, a hardwired signal with which another module can switch the charger off regardless of bus messages. The code means this signal does not behave as expected although its level is in range, for instance the charger keeps converting power after a shutdown request, or the line reports shutdown while none was commanded. No manufacturer documents P2E32 or the circuit behind it publicly. Watt & Well's EVCC charging controller offers a comparable supplier example: its hardwired emergency stop halts charging when the loop current drops to zero. CARB obliges plug-in hybrids to detect charger faults that disable or degrade charging. Low and high levels are P2E33/P2E34, charger B's twin is P2E3E. Charging is usually blocked.

Likely causes

Contact resistance or partly corroded terminal in the shutdown line
Shutdown input stage inside charger A not responding correctly
Fault or software issue in the module driving the shutdown signal

Symptoms

  • Plug-in charging refused or ended unexpectedly
  • Charging system warning message
