What P0CC3 means
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.
P0CC3 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 P0CC3
- Check-engine lamp after two trips
- Pump running constantly or not at all
- Reduced electric assist
Common causes of P0CC3
- Most likelyChafed control wire touching ground
- PossibleInternal short in the pump
- Less likelyFaulty output stage in the control module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0CC3 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. |
| C3 | The exact fault in that area. |
What to do next
- Note P0CC3 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 P0CC3
What does P0CC3 mean?
P0CC3 means "Drive Motor A Coolant Pump Control Circuit Low". P0CC3 indicates that the control line of the drive motor A coolant pump is pulled to ground. It is a generic code, so it means the same on every make.
Is it safe to drive with P0CC3?
Drive gently and only to a workshop. With P0CC3 the car can go into limp mode (reduced power) to protect itself.
Will P0CC3 fail an emissions test?
Yes, it can. P0CC3 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 P0CC3 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. This is a job for a workshop.
Will P0CC3 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.
