Display Item List

CAUTION: When malfunctions are detected in several systems, including the "CAN COMM [U1000]" and "CONTROL UNIT (CAN) [U1010]", inspect the CAN communication system.

DTC REFERENCE CHART

DTC	Diagnostic item	Diagnostic item is detected when...
C1923	STEERING ANGLE SEN [NO CHANGE]	While driving at 60 km/h (37 MPH) or more, steering angle does not change for a while.
C1924	STEERING ANGLE SEN [NO NEUT STATE]	When driving some distance, no neutral signal (ON signal) is input.
C1915	RR ST ANGLE SENSOR [MAIN SIGNAL]	The main sensor input signal is malfunctioning for some time against the sensor power supply value.
C1916	RR ST ANGLE SENSOR [SUB SIGNAL]	When the main sensor input signal is 2.4 - 2.6 V, the sub sensor input signal is malfunctioning for some time compared to the sensor power supply value.
C1917	RR ST ANGLE SENSOR [OFFSET SIG1]	An excessive difference has occurred in the input values of main sensor and sub sensor.
C1918	RR ST ANGLE SENSOR [OFFSET SIG2]
C1914	RR ST ANGLE SENSOR [ABNORMAL VOL]	Higher or lower value compared to the standard voltage.
C1921	MOTOR OUTPUT	No engine speed is input for a certain time.
C1911	MOTOR VOLTAGE [LOW VOLTAGE]	The motor power supply voltage is lower than ignition power supply voltage with RAS motor relay ON.
C1912	MOTOR VOLTAGE [BAD OBSTRCT]	The motor power supply voltage is inputting for some time with motor power supply OFF by RAS control unit.
C1913	MOTOR OUTPUT [ABNORMAL SIG]	When the motor current value is 10 A or more, actual output is excessively low and the condition continues for some time.
C1902	MOTOR OUTPUT [REV CURRENT]	The current flows in the opposite direction when the motor current is output.
C1903	MOTOR OUTPUT [NO CURRENT]	The current flows when the motor current is not output.
C1904	MOTOR OUTPUT [OVERCURRENT]	The excessive high current flows when the motor current is output.
C1910	MOTOR OUTPUT [MOTOR LOCK]	When 17 A or more current flows to the motor, the rear wheel steering angle sensor signal does not change for some time.
C1919	VEHICLE SPEED SEN [NO SIGNAL]	No vehicle speed signal is input for some time.
C1900	CONTROL UNIT [ABNORMAL1]	Control unit malfunction
C1901	CONTROL UNIT [ABNORMAL2]
C1905	CONTROL UNIT [ABNORMAL3]

C1909	CONTROL UNIT [ABNORMAL6]
C1922	CONTROL UNIT [ABNORMAL8]
C1927	CONTROL UNIT [ABNORMAL5]
C1928	CONTROL UNIT [ABNORMAL9]
C1920	STEERING ANGLE SEN [NO SIGNAL]	No steering angle signal is input for some time.
C1926	STEERING ANGLE SEN	An unexpected signal is input. Steering angle sensor outputs the malfunction signal.
C1929	VDC	ABS actuator and electric unit (control unit) outputs the malfunction signal.
U1000	CAN COMM CIRCUIT	When a RAS control unit is not transmitting or receiving CAN communication signal 2 seconds or more.
U1010	CONTROL UNIT (CAN)	When detecting error during the initial diagnosis of CAN controller of RAS control unit.
