U2007ABS valve calibration or signal check failed

• Ford code · ABS / stability control
• Lights a warning lamp

How the car detects it

The ABS module's check of its own valves failed (calibration memory or a signal comparison). Ford puts it down to an internal ABS module fault or a calibration mismatch with the hydraulic unit: clear the code and, if it returns, replace the ABS module/HCU assembly. Ford's ABS module and hydraulic unit (HCU) are serviced as one assembly. While the fault is active, ABS and stability control may be switched off; normal braking still works.
