• Traction control or stability system fault messages tied to wheel speed input
• Brake system communication issues caused by sensor wear or connector damage
• Service replacement for a damaged rear right sensor harness or connector

Installation Notes

Confirm rear right position, connector style, and harness length before installation. Inspect the wheel hub area, wiring path, and connector terminals for corrosion or damage before connecting the new sensor. Follow the included instruction sheet and verify proper routing to avoid harness strain or contact with moving suspension components.
