P0C01Drive Motor A Current High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0C01 is the overcurrent check of drive motor A, meant to protect the inverter's IGBTs. GM sets it when any phase current exceeds 725 A on the 2011 Volt, 600 A on the 2012 two-mode trucks and in the 2016 to 2019 tables, or 396 A on eAssist; since 2016 a too negative d-axis current (about -540 to -310 A, depending on stator temperature) also counts. A fast and a slow counter catch sudden and intermittent faults; Type A, one trip. GM PIP5246 links it on Volt and ELR to a damaged motor 1 stator. Stellantis lists it on the 2018/19 Wrangler eTorque (motor generator unit) and on the 2026 Wagoneer S and Cherokee, there caused by cross-threaded three-phase cable bolts. Expect limp mode.
- What you may notice
- Limp mode with warning lamp
- Reduced propulsion or engine unavailable message
- Rough running or loud noise from the motor generator
- Likely causes
- LikelyDamaged or improperly torqued three-phase cable joints (Stellantis S2608000006)
- PossibleDamaged stator winding of motor A (GM PIP5246)
- PossibleOutdated hybrid control software (Jeep TSB 08-144-23)
- RareFailing power switch or current measurement in the inverter
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
