What P0CC1 means
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.
P0CC1 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 2.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P0CC1
- Check-engine lamp after two trips
- Less electric assist and regeneration
Common causes of P0CC1
- Most likelyBroken control or supply wire to the pump
- PossibleCorroded or unplugged pump connector
- PossibleOpen winding inside the pump motor
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0CC1 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| C | Area: hybrid propulsion. |
| C1 | The exact fault in that area. |
What to do next
- Note P0CC1 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0CC1
What does P0CC1 mean?
P0CC1 means "Drive Motor A Coolant Pump Control Circuit/Open". P0CC1 concerns the control circuit of the electric pump that moves coolant through the loop of drive motor A, here specifically an open circuit. It is a generic code, so it means the same on every make.
Is it safe to drive with P0CC1?
Drive gently and only to a workshop. With P0CC1 the car can go into limp mode (reduced power) to protect itself.
Will P0CC1 fail an emissions test?
Yes, it can. P0CC1 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0CC1 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. This is a job for a workshop.
Will P0CC1 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
