This code means there's a problem with the electric pump that cools the car's motor. It's like if a fan that keeps your computer cool stopped working right.
The P0CC4 code indicates that the control circuit for the drive motor A coolant pump is experiencing a high voltage condition.
The P0CC4 code is triggered when the Powertrain Control Module (PCM) detects a voltage level that is higher than expected in the control circuit of the drive motor A coolant pump. This pump is responsible for circulating coolant to prevent the drive motor from overheating.
• Check Engine Light illuminated
• Overheating of the drive motor
• Reduced vehicle performance
• Faulty drive motor A coolant pump
• Wiring issues such as shorts or open circuits
• Faulty PCM or control module
PCM: Powertrain Control Module
Coolant: A fluid that absorbs heat from the engine
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the drive motor A coolant pump for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the drive motor A coolant pump if faulty.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

• Chevrolet Volt
• Nissan Leaf
• Toyota Prius
• Regular maintenance checks
• Ensure coolant levels are adequate
• Inspect wiring for wear and tear
Electrical Circuit Issue
• Do not ignore the Check Engine Light.
• Get the vehicle inspected by a professional.
• Avoid driving the vehicle until the issue is resolved.
Check if the vehicle's powertrain warranty covers electrical components.
This code is more common in hybrid and electric vehicles due to their reliance on electric drive motors.
High – This issue can lead to motor overheating and potential damage.
Driving with an overheating motor can cause severe damage and may be unsafe.
• Vehicle must be in operation
• Coolant system should be pressurized
The drive motor A coolant pump is typically located near the drive motor, often in the engine bay.
Q: Can I drive with a P0CC4 code?
A: It's not recommended to drive with this code as it may lead to overheating.
Q: How can I prevent this code from appearing?
A: Regular maintenance and inspections of the coolant system can help prevent this issue.
