NOTE: Refer to Description and Operation, Intelligent Access (IA) with Push Button Start in ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) to review the procedures for achieving the various ignition states (ignition in accessory, ignition on, ignition start, ignition off) on vehicles with this feature.

SYMPTOM CHART

Condition	Possible Sources	Action
The cruise control is inoperative (without adaptive cruise control)	Wiring, terminals and connectors PCM not configured for cruise control Cruise control switch Digital Transmission Range (TR) sensor Vehicle speed signal PCM Stoplamp switch	GO to Pinpoint Test A .
The cruise control is inoperative (with adaptive cruise control)	Wiring, terminals and connectors PCM not configured for cruise control Cruise control switch Digital TR sensor Vehicle speed signal PCM Stoplamp switch Cruise-Control Module (C-CM) ABS module Instrument Panel Cluster (IPC)	GO to Pinpoint Test A .
The cruise control cannot set above 130 km/h (80 mph)	A MyKey™ restricted key is in use and MyKey™ max speed limiter is turned ON	VERIFY if a MyKey™ restricted key is in use. REFER to ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) . With an admin key, VERIFY if MyKey™ max speed limiter is on. REFER to the Owner's Literature. If necessary, VERIFY cruise control normal operation with an admin key.
The cruise control indicator lamp is never/always on	Wiring, terminals and connectors PCM IPC	REFER to INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES .
The cruise control switch is inoperative/does not operate correctly	Wiring, terminals and connectors Cruise control switch Clockspring PCM	GO to Pinpoint Test C .
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)	The C-CM 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)	C-CM Blockage or obstruction Front bumper cover C-CM foam	GO to Pinpoint Test F .
Unexpected adaptive cruise control braking (if equipped with adaptive cruise control)	C-CM Front bumper cover C-CM foam	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 C-CM, front bumper cover and foam for damage. RETEST the adaptive cruise control system.
Lack of adaptive cruise control braking (if equipped with adaptive cruise control)	C-CM Front bumper cover C-CM foam	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, front bumper 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.
The stoplamps do not operate during an adaptive cruise control braking event	Adaptive cruise (stoplamps) relay	INSTALL a new adaptive cruise control (stoplamps) relay. TEST the system for normal operation.
