This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected that the electric battery system is using too much power, more than it should be.
The vehicle's onboard diagnostics system has detected that the current (or flow of electricity) in the hybrid or electric vehicle's battery system is higher than the normal operating range.
The P0D37 code is triggered when the powertrain control module (PCM) or battery energy control module (BECM) detects that the current flowing through the hybrid or electric vehicle's battery system exceeds the manufacturer's specified limits. This could be due to a fault in the battery, wiring, or control systems.
• Check engine light is on
• Reduced fuel efficiency
• Possible loss of power
• Faulty battery pack
• Short circuit in the wiring
• Defective battery control module
PCM: Powertrain Control Module
BECM: Battery Energy Control Module
• Use an OBD-II scanner to confirm the code.
• Inspect the battery pack and wiring for damage.
• Test the battery control module for faults.
• Replace the faulty battery pack.
• Repair or replace damaged wiring.
• Replace the defective battery control module.
• OBD-II scanner
• Multimeter
• Insulated tools for high voltage systems

Battery System Issue
• Do not drive the vehicle until it is inspected.
• Contact a certified technician for diagnosis.
Battery-related issues may be covered under the vehicle's warranty. Check with your manufacturer.
This code has become more common with the increase in hybrid and electric vehicles, highlighting the importance of battery management systems.
High – This issue can lead to vehicle performance problems and potential safety risks.
Driving with a malfunctioning battery system can be dangerous and may violate emissions regulations.
• Vehicle in ON position
• Battery system under load
The battery system is typically located in the rear of the vehicle or under the floor in electric vehicles.
Q: Can I drive with a P0D37 code?
A: It's not recommended to drive with this code as it indicates a serious issue with the battery system.
Q: What happens if I ignore this code?
A: Ignoring this code can lead to further damage to the battery system and potential safety hazards.
