C146E 2015 Toyota RAV4 Code - Open In ABS Solenoid Relay Circuit

C146E indicates an "Open in ABS Solenoid Relay Circuit," meaning there may be an electrical issue with the Anti-lock Braking System (ABS) solenoid relay or its circuit.

Common symptoms include the ABS warning light being illuminated, traction control system deactivation, and potential loss of ABS functionality during braking.

Causes include a faulty ABS solenoid relay, an open or damaged wiring harness, corroded or loose electrical connections, or, less commonly, a malfunctioning ABS control module.

Yes, you can drive the vehicle, but the ABS and traction control systems may not function properly, increasing the risk of wheel lock-up during hard braking or loss of traction in slippery conditions.

Use an OBDII scanner to confirm the code, then inspect the ABS solenoid relay, wiring, and connectors for damage or corrosion. Check for continuity in the circuit and ensure the relay is functioning.

Repairs may involve replacing a faulty ABS solenoid relay, repairing or replacing damaged wiring, cleaning corroded connections, or, in rare cases, replacing the ABS control module.

The repair cost depends on the issue. Replacing an ABS solenoid relay typically costs $50–$150 for parts, plus labor. Wiring repairs or ABS control module replacement may cost more.

Yes, a weak or low battery can cause voltage issues that may trigger the C146E code. Ensure the battery is fully charged and functioning correctly before further diagnosis.

Yes, after completing the necessary repairs, use an OBDII scanner to clear the code and verify that it does not return during a test drive.

Yes, a faulty ABS solenoid relay can impact the traction control system and stability control, as these systems rely on the ABS to function correctly.
