SYMPTOM CHART

Condition	Possible Sources	Action
The speed control is inoperative (without adaptive cruise control)	Wiring, terminals and connectors PCM not configured for speed control Speed control switches Digital Transmission Range (TR) sensor Vehicle speed signal PCM	Go To PINPOINT TEST A .
The speed control is inoperative and the message center displays "CRUISE CONTROL NOT AVAILABLE." (with adaptive cruise control)	Wiring, terminals and connectors PCM not configured for speed control Speed control switch Speed control sensor alignment Digital TR sensor Vehicle speed signal PCM Cruise-Control Module (C-CM) ABS module	Go To PINPOINT TEST A .
The speed control indicator lamp is never/always on	Wiring, terminals and connectors PCM Instrument Panel Cluster (IPC)	REFER to INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES .
The adaptive cruise control indicator lamp is never/always on	Wiring, terminals and connectors PCM IPC	REFER to INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES .
The amber follow indicator is flashing and the adaptive cruise control does not activate (if equipped with adaptive cruise control)	The speed control sensor has not completed the horizontal alignment	Drive the vehicle until the amber follow indicator stops flashing.
The adaptive cruise control does not function in rain or snow conditions (if equipped with adaptive cruise control)	Speed control sensor fascia cover (early build) Speed control sensor fascia cover foam Front bumper cover (late build)	Go To PINPOINT TEST N .
Unexpected adaptive cruise control braking (if equipped with adaptive cruise control)	Speed control sensor Speed control sensor fascia cover (early build) Speed control sensor fascia cover foam Front bumper cover (late build)	The adaptive cruise control system may occasionally detect and respond to out-of-path vehicles, especially on curves, entry/exit ramps or when changing lanes. CHECK the speed control sensor, front fascia cover and foam for damage. RETEST the adaptive cruise control system.
Lack of adaptive cruise control braking (if equipped with adaptive cruise control)	Speed control sensor Speed control sensor fascia cover (early build) Speed control sensor fascia cover foam Front bumper cover (late build)	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 speed control sensor field of view. CHECK the speed control sensor, front fascia cover and foam for damage. If no damage is observed, RETEST the adaptive cruise control system.
Noise during adaptive cruise control braking (if equipped with adaptive cruise control)	Low speeds Brake concern	The driver may detect some noise at low speeds when adaptive cruise control braking occurs. If braking noise continues, REFER to BRAKE SYSTEM-GENERAL INFORMATION to continue diagnosis of the ABS system.
