This summary uses the existing diagnostic information shown in full below.
This code means that the computer in your car has detected a problem with the power supply to the electric motor's control module. It's like when your toy stops working because the batteries are too strong.
The control module for the drive motor is receiving a higher voltage than expected, which can affect its performance.
The P1A96 code indicates that the drive motor 'A' control module is detecting a higher than normal voltage in its 5V power supply circuit. This can be due to a malfunctioning voltage regulator or a short circuit within the control module or associated wiring.
• Check Engine Light is on
• Reduced vehicle performance
• Unusual noises from the motor
• Faulty voltage regulator
• Short circuit in the wiring
• Defective control module
Control Module: A computer in the vehicle that controls various functions.
Voltage Regulator: A device that maintains a constant voltage level.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the voltage regulator and control module.
• Replace the voltage regulator if faulty.
• Repair or replace damaged wiring.
• Replace the control module if necessary.
• OBD-II Scanner
• Multimeter
• Screwdriver set

Moderate
• Chevrolet Volt
• Nissan Leaf
• Toyota Prius
• Regularly inspect electrical connections.
• Keep the vehicle's software updated.
• Perform routine maintenance checks.
Electrical Issue
• Do not ignore the Check Engine Light.
• Consult a professional mechanic for diagnosis.
• Avoid driving the vehicle until repaired.
Check if the vehicle's powertrain warranty covers the control module.
This code is more common in hybrid and electric vehicles due to their reliance on electric drive systems.
High – Driving with this issue can lead to further damage to the vehicle's electrical system.
Driving with a malfunctioning control module can be unsafe and may not comply with emissions regulations.
• Vehicle in 'ON' position
• Battery fully charged
The drive motor control module is typically located near the vehicle's electric drive motor, often in the engine bay or under the vehicle.
Q: Can I drive my car with a P1A96 code?
A: It's not recommended as it can lead to further damage and potential safety issues.
Q: Will the P1A96 code clear itself?
A: The code may clear temporarily, but the underlying issue needs to be fixed to prevent it from returning.
