ISSUE
Some 2007 Expedition and Navigator vehicles built before 02/15/2007 may experience an ABS light on and the base brake system continuing to function normally. This may be due to corrosion in the connector of the rear wheel speed sensor.

SERVICE PROCEDURE
Follow normal Workshop Manual (WSM) diagnostics. If the diagnostics lead to replacement of the rear wheel speed sensor, follow these steps to prevent water leaking into the connector.
1. Disconnect the rear wheel speed sensor connector.
2. Inspect the female terminals, on the harness side of the connector (C440 and C426).
