Right Front ABS Outlet Solenoid B Circuit Malfunction
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
The ABS module has detected an electrical fault in the secondary outlet solenoid for the right front wheel. ABS and stability control are disabled while the fault is active.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
