This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected that the power going to the part of the car that controls the electric motor is too high. It's like if you plugged a lamp into a socket and the electricity was too strong for the lamp.
The drive motor control module is receiving a higher voltage than expected from the 12V power supply circuit.
The P1DC0 code indicates that the drive motor 'A' control module is experiencing a voltage that is higher than the specified range from its 12V power supply circuit. This could be due to a malfunction in the power supply, wiring issues, or a fault within the control module itself.
• Check Engine Light is on
• Reduced vehicle performance
• Vehicle may not start or drive properly
• Faulty drive motor control module
• Wiring issues such as short circuits or poor connections
• Defective 12V power supply
Drive Motor: The electric motor that powers the vehicle.
Control Module: A computer that manages specific functions in the vehicle.
• Check for any other related codes and address them first.
• Inspect the wiring and connections to the drive motor control module.
• Measure the voltage at the control module to ensure it is within the specified range.
• Repair or replace any damaged wiring or connectors.
• Replace the drive motor control module if it is found to be faulty.
• Ensure the 12V power supply is functioning correctly.
• Multimeter

Electrical Circuit Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if you notice any performance issues.
Check with your vehicle manufacturer for warranty coverage on electrical components.
This code is commonly associated with hybrid and electric vehicles due to their complex electrical systems.
Moderate – Addressing this issue promptly can prevent further damage to the vehicle's electrical system.
Driving with this error code may not be safe as it can affect vehicle performance. Consult a professional mechanic.
• Vehicle must be in a safe, stable condition.
• Ensure the vehicle is off and the battery is disconnected before inspecting wiring.
The drive motor control module is typically located near the electric motor or in the engine bay.
