This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer found a problem with the power supply to the electric motor's control module. It's like when a toy doesn't work because the batteries are running low.
The P1A95 code is triggered when the vehicle's control module detects that the 5V power supply to the drive motor 'A' control module is lower than expected.
The drive motor control module requires a stable 5V power supply to function correctly. If this voltage drops below a certain threshold, it can cause the module to malfunction, leading to potential issues with the electric motor's performance.
• Reduced vehicle performance
• Warning light on the dashboard
• Electric motor not functioning properly
• Faulty drive motor control module
• Wiring issues or poor connections
• Defective power supply components
Control Module: A device that manages the operations of a vehicle's system.
5V Power Supply: A voltage supply that provides 5 volts of electricity.
• Check for any loose or damaged wiring to the control module.
• Measure the voltage at the control module to ensure it is receiving the correct 5V supply.
• Inspect the drive motor control module for any signs of damage or failure.
• Repair or replace any damaged wiring or connectors.
• Replace the drive motor control module if it is found to be faulty.
• Ensure the power supply components are functioning correctly and replace if necessary.
• Multimeter
• OBD-II scanner
• Basic hand tools

Moderate
• Chevrolet Volt
• Nissan Leaf
• Toyota Prius
• Regularly check and maintain electrical connections.
• Ensure the vehicle's battery and charging system are in good condition.
• Perform routine diagnostics to catch issues early.
Electrical System Issue
• Do not ignore the warning light; get the vehicle checked as soon as possible.
• Avoid driving the vehicle if you notice significant performance issues.
Check with the vehicle manufacturer to see if the control module is covered under warranty.
This code is more common in hybrid and electric vehicles due to their reliance on electric drive systems.
Moderate – It is important to address this issue to prevent further damage to the vehicle's electric drive system.
Driving with this issue may not be safe, as it can affect the vehicle's performance. Always address warning lights promptly.
• Vehicle must be in a safe location for testing.
• Ensure the battery is fully charged before starting diagnostics.
The drive motor control module is typically located near the vehicle's electric motor or within the engine compartment.
Q: Can I drive my car with a P1A95 code?
A: It's not recommended to drive with this code active, as it can affect the vehicle's performance and safety.
Q: How do I reset the P1A95 code?
A: After repairing the issue, you can reset the code using an OBD-II scanner. However, ensure the problem is fixed first.
