What does P2D68 mean?

The negative contactor C of the battery charging system reports a control circuit high condition. HV charging path cannot be commanded reliably.

The code tells you which monitor failed, not which part is broken. Test before replacing parts.

Common causes

  • High Control wire shorted to B+
  • Medium Open contactor coil
  • Low Connector pins corroded - high contact resistance

Likelihood is a general estimate across vehicles; your make and model may differ.
