Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. REFER to SERVICE INFORMATION , Diagnostic Methods for information regarding Ford-specific diagnostic practices.

Condition	Possible Sources	Actions
The cruise control is inoperative	Cruise control switches (part of the message center switch) Cruise control deactivator switch (integral to the stoplamp switch) Digital TR sensor Vehicle speed signal PCM Stoplamp switch SCCM	REFER to Cruise Control - Non-Adaptive, GO to Pinpoint Test A .
The cruise control switch is inoperative/does not operate correctly	Wiring, terminals and connectors Clockspring Cruise control switches (part of the message center switch) SCCM	REFER to Cruise Control - Non-Adaptive, GO to Pinpoint Test C .
The adaptive cruise control does not function in rain or snow conditions	C-CM Blockage or obstruction Front bumper cover	GO to Pinpoint Test F .
"ADAPTIVE CRUISE NOT AVAILABLE SENSOR BLOCKED" message in the IPC message center	C-CM Blockage or obstruction Front bumper cover	GO to Pinpoint Test F .
Unexpected adaptive cruise control braking	C-CM Front bumper cover	The adaptive cruise control system can occasionally detect and respond to out-of-path vehicles, especially on curves, entry/exit ramps or when changing lanes. CHECK the C-CM and front bumper cover for damage. RETEST the adaptive cruise control system.
Lack of adaptive cruise control braking	C-CM Front bumper cover	The adaptive cruise control system may not detect and respond to vehicles carrying out close cut-ins or on tight curves (especially for vehicles on the passenger side) due to limited C-CM field of view. CHECK the C-CM and front bumper cover for damage. If no damage is observed, RETEST the adaptive cruise control system.
Noise during adaptive cruise control braking	Normal operation	The driver can detect some noise at low speeds when adaptive cruise control braking occurs. This is normal operation. No repair is necessary.
The cruise control cannot set speed above 128.7 kmh (80 mph)	A MyKey® restricted key is in use and MyKey® max speed limiter is turned on	VERIFY whether a MyKey® restricted key is in use. With an admin key, VERIFY if MyKey® max speed limiter is turned on. REFER to the Owner's Literature. If necessary, VERIFY cruise control normal operation with an admin key. REFER to the Owner's Literature.
