Code C0247 Description
The diagnostic trouble code C0247 indicates a problem with the Left Front Isolation Solenoid Circuit being shorted. The isolation solenoid is a crucial component of the vehicle's anti-lock braking system (ABS), responsible for controlling the hydraulic pressure to the left front wheel during braking. When the circuit is shorted, it means that there is an abnormal electrical connection that is disrupting the solenoid's operation. This can lead to issues with the ABS system, potentially affecting the vehicle's braking performance and stability.
Common Causes of C0247
- Damaged wiring or connectors related to the Left Front Isolation Solenoid
- Faulty isolation solenoid
- Corrosion or rust affecting the electrical connections
- Poor electrical ground connection
- Water or moisture ingress into the ABS system
Symptoms of C0247
- Illuminated ABS warning light on the dashboard
- Loss of ABS functionality
- Increased stopping distance during braking
- Uneven braking or pulling to one side
- Unusual noises coming from the ABS system during operation
How to Fix C0247
- Begin by conducting a thorough inspection of the wiring, connectors, and isolation solenoid for any visible damage or corrosion.
- Test the electrical connections using a multimeter to identify the source of the short circuit.
- Replace any damaged wiring, connectors, or the isolation solenoid as necessary.
- Clear the diagnostic trouble code from the vehicle's computer system using a scan tool.
- Perform a road test to ensure that the ABS system is functioning correctly and that the issue has been resolved.
Cost to Fix C0247
The typical repair costs for addressing a Left Front Isolation Solenoid Circuit Shorted code can range from $200 to $500, including parts and labor.
