P0CC3Drive Motor A Coolant Pump Control Circuit Low
- 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
- P0CC3 indicates that the control line of the drive motor A coolant pump is pulled to ground. GM lists it for the 2013 eAssist cars in table 13OBDG05C: the hardware status of the output driver signals a low-circuit fault, and 20 of 25 samples at 250 ms with the pump commanded off and the vehicle in run/crank fail the test, Type B, so the MIL is lit after the second trip. Typical are chafed insulation where the harness passes brackets or the engine, or a pump with an internal short. Depending on how the driver stage is built, a grounded line can also leave the pump running permanently or stop it, so either constant pump noise or missing cooling is possible. Compared with the open-circuit code P0CC1 and the short-to-voltage code P0CC4, the repair focuses on finding the point of ground contact.
