C146F 2017 Toyota RAV4 Code - Short in ABS Solenoid Relay Circuit

The code C146F indicates a "Short in ABS Solenoid Relay Circuit," meaning there is a problem with the electrical circuit controlling the ABS solenoid relay.

Symptoms may include the ABS warning light illuminating, reduced braking performance, and the ABS system not functioning properly.

Common causes include a short circuit in the ABS solenoid relay wiring, a faulty ABS solenoid relay, damaged connectors, or a malfunctioning ABS control module.

While the vehicle may still be drivable, the ABS system may not function correctly, which can affect your ability to brake safely in certain conditions.

Diagnosis typically involves inspecting the ABS solenoid relay, checking for damaged or shorted wiring, testing the relay itself, and possibly scanning the ABS control module for additional faults.

You may need a diagnostic scan tool, a multimeter to test circuits, and wiring diagrams for the ABS system.

Repairs may involve replacing the ABS solenoid relay, repairing or replacing damaged wiring, cleaning or securing connectors, or replacing the ABS control module if necessary.

The ABS solenoid relay controls power to the solenoids that manage brake fluid pressure during ABS operation, ensuring proper anti-lock braking function.

Repair costs vary but typically range from $100 to $500, depending on whether the issue is a simple wiring repair or a more complex component replacement.

A low battery is unlikely to directly cause the C146F code, but electrical issues related to a weak battery or poor connections could contribute to similar problems.
