P2D60 Battery Charging System Positive Contactor C Control Circuit Low

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

P2D60 is logged when the coil feed of positive charging contactor C reads lower than commanded – usually the wire has found ground or the driver output is dragged low. Where the driver switches the supply side, the coil then gets too little current and the contactor stays open, or the driver shuts itself off for protection. No manufacturer documents P2D60 publicly. GM's table for the contactor A twin (P0D0A) on the Volt states that its open-load test is blind to a ground short, so a low fault needs a separate check. CARB lets makers report open, shorted-low and shorted-high output faults under one code, so some systems may never set this one. Typical finds: insulation rubbed through at the battery housing, water in a plug. P2D61 is the high case, P2D67 the minus side.

Likely causes

Coil feed wire shorted to ground
Moisture or corrosion in the contactor plug
Shorted turns in the coil of contactor C

Symptoms

  • Affected charging mode refused
  • Fault may appear only in wet weather
