1	Cruise control main switch is not turned to ON. (CRUISE indicator light does not illuminate.) Or cruise control is cancelled without operating the cruise control command switch.	(1) Read the cancel code of the ECM.	Perform the diagnosis according to displayed cancel code. < Refer to ECM , LIST, List of Cancel Code. > If not displayed, go to (2).
		(2) Perform the real-time diagnosis. Check the input signal of cruise control system.	< Refer to REAL-TIME DIAGNOSIS . > When normal, go to (4). When abnormal, go to (3).
		(3) Check the cruise control command switch.	< Refer to CHECK CRUISE CONTROL COMMAND SWITCH , Diagnostics with Phenomenon. >
		(4) Check the CRUISE indicator.	< Refer to CHECK CRUISE INDICATOR LIGHT AND CRUISE SET INDICATOR LIGHT , Diagnostics with Phenomenon. >
2	Cruise control cannot be set. Or cruise control is cancelled without releasing operation. NOTE: Do not turn the ignition switch to OFF after the cruise control is deactivated. Do not operate the cruise control command switch after the cruise control is deactivated. If the above is performed, the cancel code the ECM will be cleared.	(1) Read the cancel code of the ECM.	Perform the diagnosis according to displayed cancel code. < Refer to LIST OF CANCEL CODE . > If not displayed, go to (2).
		(2) Perform the real-time diagnosis. Check the input signal of cruise control system.	< Refer to REAL-TIME DIAGNOSIS . > When normal, go to (6). When abnormal, go to the relevant items for (3), (4), (5).
		(3) Check the cruise control command switch.	< Refer to CHECK CRUISE CONTROL COMMAND SWITCH , Diagnostics with Phenomenon. >
		(4) Check stop light switch and brake switch.	< Refer to BRAKE PEDAL . > < Refer to 12 , Diagnostic Procedure with Cancel Code. >
		(5) Check the neutral position switch.	< Refer to 14 , Diagnostic Procedure with Cancel Code. > < Refer to 62 , Diagnostic Procedure with Cancel Code. >
		(6) Check vehicle speed sensor.	< Refer to 22 , Diagnostic Procedure with Cancel Code. >
3	SET indicator does not illuminate.	Check the SET indicator.	< Refer to CHECK CRUISE INDICATOR LIGHT AND CRUISE SET INDICATOR LIGHT , Diagnostics with Phenomenon. >
4	Vehicle speed is not held within set speed ±3 km/h (±2 MPH) on a level road.	Check the vehicle speed sensor.	< Refer to 22 , Diagnostic Procedure with Cancel Code. >
5	Vehicle speed does not increase or does not return to set speed after RES/+ switch has been pressed.	(1) Perform the real-time diagnosis. Check the input signal of cruise control system.	< Refer to REAL-TIME DIAGNOSIS . > When abnormal, go to (2).
5		(2) Check the RES/+ switch.	< Refer to CHECK CRUISE CONTROL COMMAND SWITCH , Diagnostics with Phenomenon. >
6	Vehicle speed does not decrease after SET/- switch has been pressed.	(1) Perform the real-time diagnosis. Check the input signal of cruise control system.	< Refer to REAL-TIME DIAGNOSIS . > When abnormal, go to (2).
6		(2) Check the SET/- switch.	< Refer to CHECK CRUISE CONTROL COMMAND SWITCH , Diagnostics with Phenomenon. >
7	Cruise control is not released after CANCEL switch has been pressed.	(1) Perform the real-time diagnosis. Check the input signal of cruise control system.	< Refer to REAL-TIME DIAGNOSIS . > When abnormal, go to (2).
7		(2) Check the CANCEL switch.	< Refer to CHECK CRUISE CONTROL COMMAND SWITCH , Diagnostics with Phenomenon. >
8	Cruise control is not released after brake pedal has been depressed.	(1) Perform the real-time diagnosis. Check the input signal of cruise control system.	< Refer to REAL-TIME DIAGNOSIS . > When abnormal, go to (2).
8		(2) Check stop light switch and brake switch.	< Refer to 12 , Diagnostic Procedure with Cancel Code. > < Refer to INSTALLATION , Stop Light Switch. >
9	Cruise control is not released after shifting to the neutral position.	(1) Perform the real-time diagnosis. Check the input signal of cruise control system.	< Refer to REAL-TIME DIAGNOSIS . > When abnormal, go to (2).
9		(2) Check the neutral position switch.	< Refer to 14 , Diagnostic Procedure with Cancel Code. >
10	Acceleration or deceleration does not occur according to the preceding vehicle. The preceding vehicle is difficult to be detected. Braking force is weaker than usual. Alarm for requiring more brake pedal force does not sound.	(1) Using CHECK LIST (ADAPTIVE CRUISE CONTROL), check the condition and respond to it. Is this applied to the condition that the use of adaptive cruise control is not desired? Is this applied to the object or condition that is hard to be recognized by the stereo camera? Is this applied to the driving condition that the preceding vehicle cannot be recognized or the vehicle on the next lane or the object on the roadside may be recognized by mistake? Is this applied to the condition that brake force may become poor? Is this applied to the condition that the alarm for requiring more brake pedal force does not sound even in a short vehicle distance?	< Refer to CHECK LIST (ADAPTIVE CRUISE CONTROL) , DIAGNOSTIC PROCEDURE WITH PHENOMENON, Diagnostics with Phenomenon. > When there is a relevant item in the check list, it can be the cause of malfunction. Eliminate the cause, and check that the malfunction has been improved. If not solved, go to (2).
		(2) Check the windshield glass and dashboard.	< Refer to WINDSHIELD GLASS AND DASHBOARD , INSPECTION, General Description. > When normal, go to (3).
		(3) Check the front wiper.	< Refer to FRONT WIPER , INSPECTION, General Description. > When normal, go to (4).
		(4) Check the stereo camera.	< Refer to STEREO CAMERA , INSPECTION, General Description. > When normal, go to (5).
		(5) Bleed air from brake system.	< Refer to BRAKE LINE , PROCEDURE, Air Bleeding. > When normal, go to (6).
		(6) Check the optical axis of the stereo camera.	Adjust the optical axis of the stereo camera. < Refer to PROCEDURE , Camera Adjustment, Inspection. >
