This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer found a problem with how the battery's voltage and current sensors are working together. It's like the sensors aren't agreeing on how much power the battery has.
The car's computer monitors the voltage and current from the battery pack using sensors. This code indicates a mismatch or correlation error between these sensors.
The P1C97 code is triggered when the Universal Charger Extension Control Module detects a discrepancy between the voltage sensor and the current sensor readings from the DC/DC converter and hybrid/EV battery pack. This could indicate a faulty sensor, wiring issue, or a problem with the control module itself.
• Check Engine Light on
• Reduced vehicle performance
• Battery charging issues
• Possible stalling or hesitation
• Faulty voltage sensor
• Faulty current sensor
• Wiring or connection issues
• Faulty Universal Charger Extension Control Module
DC/DC Converter: A device that converts direct current (DC) from one voltage level to another.
Hybrid/EV Battery Pack: A set of batteries used to power electric and hybrid vehicles.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections to the sensors.
• Test the voltage and current sensors for proper operation.
• Check the Universal Charger Extension Control Module for faults.
• Replace faulty voltage or current sensor.
• Repair or replace damaged wiring or connectors.
• Replace the Universal Charger Extension Control Module if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Volt
• Toyota Prius
• Nissan Leaf
• Regular maintenance of battery and sensors.
• Ensure proper connections and wiring integrity.
• Update vehicle software as recommended by the manufacturer.
Sensor Issue
• Avoid driving the vehicle until the issue is resolved to prevent further damage.
• Consult with a certified mechanic for a thorough inspection.
Check with the vehicle manufacturer for warranty coverage on hybrid/EV components.
This code has become more common with the increasing use of hybrid and electric vehicles, as they rely heavily on accurate sensor data.
Moderate – It is important to address this issue to ensure the vehicle operates efficiently and safely.
Driving with this code may lead to reduced vehicle performance and efficiency. It is advisable to have the issue diagnosed and repaired promptly.
• Vehicle must be in 'Ready' mode.
• Battery pack should be charged to at least 50%.
The sensors and control module are typically located near the battery pack, often under the vehicle or in the trunk area for hybrid/EV models.
Q: What happens if I ignore this code?
A: Ignoring this code can lead to reduced vehicle performance and potential damage to the battery or charging system.
Q: Can I fix this issue myself?
A: If you have experience with automotive electronics and the right tools, you may be able to diagnose and repair the issue. Otherwise, it's best to consult a professional.
