P0CC1Drive Motor A Coolant Pump Control Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P0CC1 concerns the control circuit of the electric pump that moves coolant through the loop of drive motor A, here specifically an open circuit. GM documents it for the 2013 eAssist hybrids, where the table 13OBDG05C calls the part the motor generator coolant pump: the output driver reports an open-circuit status, and 20 of 25 checks at 250 ms intervals with the vehicle in run/crank and the pump commanded off fail the test, Type B, two trips. Checking in the off state lets the driver detect a missing load without running the pump. A broken wire, a corroded pump connector or an open motor winding are typical causes. With the pump not reachable, the motor generator cannot be cooled actively, so the system is likely to limit assist and charging; the short codes P0CC3 and P0CC4 belong to the same circuit.
- What you may notice
- Check-engine lamp after two trips
- Less electric assist and regeneration
- Likely causes

- PossibleCorroded or unplugged pump connector
- PossibleOpen winding inside the pump motor
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
