P2D80: Charging Start Switch Circuit Low

Standardized SAE J2012 code · P2Dxx codes

What does P2D80 mean?

The charging start switch reports a circuit low condition. Charging initiation cannot be reliably commanded by the operator.

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

Common causes

  • High Signal wire shorted to ground
  • Medium Switch stuck off
  • Low Connector pins corroded - high contact resistance

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

Add your car to see reports of P2D80 on the same make and model first.
