P0C00 Drive Motor A Current Low

Check engine lightOn
EmissionsRelevant
Drive cycleNot required
Limp modePossible

P0C00 reports that the current of drive motor A is lower than the controller expects for the commanded torque, the counterpart of P0C01 (current high). No manufacturer documents this exact code publicly; GM and Stellantis use only P0C01 from this group. CARB requires hybrids to monitor electric motor performance. Too little current points to a high-resistance three-phase joint, an open winding path or an inverter that cannot drive the phases. GM checks a missing phase separately as P0C05. The driver usually notices weak electric drive and a warning lamp; the vehicle may switch to engine-only or limp mode.

Likely causes

High-resistance or loose three-phase connection at motor A or the inverter
Inverter power stage for motor A not delivering current
Open or damaged winding in drive motor A

Symptoms

  • Weak or missing electric drive torque
  • Malfunction indicator lamp or hybrid system warning
  • Vehicle runs on the engine only or in limp mode
