This summary uses the existing diagnostic information shown in full below.
This code means that there's a problem with the electrical system that turns off the hybrid or electric car's battery. It's like a switch that isn't working right.
The P2C97 code indicates that the circuit responsible for disabling the hybrid or EV battery is experiencing low voltage, which can affect the vehicle's ability to manage its battery safely.
The P2C97 diagnostic trouble code is set when the vehicle's powertrain control module (PCM) detects a low voltage condition in the hybrid or electric vehicle's battery disable circuit. This circuit is crucial for safely disconnecting the high-voltage battery during certain conditions, such as maintenance or a crash.
• Check engine light is on
• Vehicle may not start
• Reduced performance in hybrid/EV mode
• Faulty battery disable switch
• Wiring issues in the battery disable circuit
• Malfunctioning powertrain control module (PCM)
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the battery disable switch and related wiring for damage.
• Check the PCM for any faults or updates.
• Replace or repair the battery disable switch.
• Fix any damaged wiring in the circuit.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Wiring repair tools

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regularly inspect the battery disable circuit.
• Ensure all software updates are applied to the PCM.
• Avoid tampering with high-voltage components.
Electrical Circuit Issue
• Do not attempt to repair high-voltage components yourself.
• Consult a certified hybrid/EV technician for repairs.
Repairs may be covered under the vehicle's powertrain or hybrid/EV warranty.
This code has become more common with the rise of hybrid and electric vehicles as they rely on complex electrical systems.
High – This issue can affect vehicle safety and performance.
Handling high-voltage systems can be dangerous. Always follow safety guidelines and consult professionals.
• Vehicle must be in a safe, stationary position.
• Ensure the vehicle's battery is charged.
The battery disable circuit is typically located near the vehicle's high-voltage battery pack.
Q: Can I drive my car with this code?
A: It's not recommended to drive the vehicle with this code, as it can affect the safety and performance of the hybrid/EV system.
Q: Is this a common issue?
A: It can occur in hybrid and electric vehicles due to the complexity of their electrical systems.
