C146F 2014 Toyota RAV4 Code - Short in ABS Solenoid Relay Circuit

Code C146F indicates a "Short in ABS Solenoid Relay Circuit," meaning there’s an electrical issue in the circuit controlling the ABS solenoid relay.

Common symptoms include the ABS warning light turning on, reduced or non-functional ABS, and possibly decreased braking performance.

This code is typically caused by a short circuit in the ABS solenoid relay, damaged wiring, a faulty ABS solenoid relay, or a malfunctioning ABS control module.

While the vehicle may still be drivable, it’s unsafe as the ABS may not function properly, increasing the risk of skidding or losing control during hard braking.

Diagnosis involves checking the ABS solenoid relay, inspecting wiring and connectors for damage or shorts, and testing the ABS control module for faults.

Repairs may include replacing the ABS solenoid relay, repairing or replacing damaged wiring, or, in rare cases, replacing the ABS control module.

Repair costs can range from $100 to $500 depending on whether it’s a simple relay replacement or more extensive wiring or module repairs.

A dead or weak battery alone is unlikely to cause this code but could exacerbate electrical issues that lead to it, such as voltage irregularities.

Clearing the code will reset the warning temporarily, but the underlying issue must be repaired to prevent the code and symptoms from returning.

If you have basic automotive repair skills and the correct tools, you can replace the relay yourself. However, diagnosing the issue fully is recommended to ensure it’s the root cause.
