Code C146E Description
The diagnostic trouble code C146E indicates an "Open in ABS Solenoid Relay Circuit" in the vehicle's anti-lock braking system (ABS). The ABS solenoid relay is a crucial component that controls the activation and deactivation of the ABS system, which helps prevent the wheels from locking up during emergency braking situations. An open circuit in the ABS solenoid relay circuit means that there is a break or interruption in the electrical connection, preventing the relay from functioning properly.
Common Causes of C146E
- Corrosion or damage to the wiring harness
- Loose or disconnected electrical connections
- Faulty ABS solenoid relay
- Water or debris intrusion in the ABS system
- Electrical short circuits in the system
Symptoms of C146E
- ABS warning light illuminated on the dashboard
- Loss of ABS functionality during braking
- Increased stopping distance
- Traction control system malfunctions
- Skidding or slipping on slippery roads
How to Fix C146E
- Diagnose the ABS system with a scan tool to retrieve the trouble code and pinpoint the location of the open circuit.
- Inspect the wiring harness and electrical connections for any damage, corrosion, or loose connections.
- Test the ABS solenoid relay for proper functionality and replace if necessary.
- Clear the trouble code from the system and perform a road test to ensure the ABS system is operating correctly.
- If the issue persists, further diagnostic testing may be required to identify any underlying electrical faults or component failures.
Cost to Fix C146E
The cost of repairing an open circuit in the ABS solenoid relay circuit can vary depending on the extent of the damage and the specific components that need to be replaced. On average, the parts for this repair can range from $100 to $300, while the labor costs can add another $100 to $200 to the total bill. Keep in mind that these are rough estimates, and actual repair costs may vary based on the vehicle make and model, as well as the shop's labor rates. It's recommended to consult with a trusted mechanic or repair shop for a more accurate cost estimate based on your specific vehicle and location.
