C1235 on Ford
Right rear wheel speed sensor input missing (Ford)
Severity: Inspect soon
A Windstar owner reports the ABS light on and says anti-lock is not affected, but a missing wheel speed signal normally disables ABS; Ford bulletin summaries pair it with an amber ABS lamp.
It gets more serious if:
- Stop: Stop and have it checked if the red BRAKE light comes on as well as the ABS light.
