WARNING: This page is about a different car, the 2011 Suzuki Equator. However, it is still accessible from the selected car via links, so may be relevant.

DTC CHART

DTC	SDT	Diagnostic item is detected when...	Reference
[P1801]	INITIAL START	Due to removal of battery which cuts off power supply to transfer control unit, self-diagnosis memory function is suspended.	P1801, P1811 Power Supply Circuit for Transfer Control Unit
[P1802]	CONTROL UNIT (1, 2, 3)	Malfunction is detected in the memory (RAM) system of transfer control unit.	P1802 - P1804, P1809 Transfer Control Unit
[P1803]		Malfunction is detected in the memory (ROM) system of transfer control unit.
[P1804]		Malfunction is detected in the memory (EEPROM) system of transfer control unit.
[P1807]	VHCL SPEED SEN.AT	Malfunction is detected in output shaft revolution signal that is output from TCM through CAN communication. Improper signal is input while driving.	P1807 Vehicle Speed Sensor (A/T)
[P1808]	VHCL SPEED SEN.ABS	Malfunction is detected in vehicle speed signal that is output from ABS actuator and electric unit (control unit) through CAN communication. Improper signal is input while driving.	P1808 Vehicle Speed Sensor (ABS)
[P1809]	CONTROL UNIT 4	AD converter system of transfer control unit is malfunctioning.	P1802 - P1804, P1809 Transfer Control Unit
[P1810]	4L POSI SW TF	Improper signal from 4LO switch is input due to open or short circuit.	P1810 4 LO Switch
[P1811]	BATTERY VOLTAGE	Power supply voltage for transfer control unit is abnormally low while driving.	P1801, P1811 Power Supply Circuit for Transfer Control Unit
[P1813]	4WD MODE SW	More than two switch inputs are simultaneously detected due to short circuit of 4WD shift switch.	P1813 4WD Shift Switch
[P1814]	4WD DETECT SWITCH	Improper signal from wait detection switch is input due to open or short circuit.	P1814 Wait Detection Switch
[P1816]	PNP SW/CIRC	When PNP switch signal is malfunctioning.	P1816 PNP Switch (A/T) (A/T models), P1816 PNP Switch (M/T) (M/T models)
[P1817]	SHIFT ACTUATOR	Motor does not operate properly due to open or short circuit in actuator motor. Malfunction is detected in the actuator motor. (When 4WD shift switch is operated and actuator motor is not operated) Malfunction is detected in transfer shift high relay or transfer shift low relay.	P1817 Actuator Motor
[P1818]	SHIFT ACT POSI SW	Improper signal from actuator position switch is input due to open or short circuit. Malfunction is detected in actuator position switch.	P1818 Actuator Position Switch
[P1819]	SHIFT ACT CIR	Malfunction is detected in transfer shut off relay 1 and transfer shut off relay 2. Malfunction occurs in transfer control device drive circuit.	P1819 Transfer Control Device
[P1820]	ENGINE SPEED SIG	Malfunction is detected in engine speed signal that is output from ECM through CAN communication. Improper signal is input while driving.	P1820 Engine Speed Signal
[U1010]	CONTROL UNIT (CAN)	Detecting error during the initial diagnosis of CAN controller of transfer control unit.	U1010 Control Unit (CAN)

NOTE: If "SHIFT ACT POSI SW [P1818]" or "SHIFT ACT CIR [P1819]" is displayed, first erase DTC. ("SHIFT ACT POSI SW [P1818]" or "SHIFT ACT CIR [P1819]" may be displayed after installing transfer control unit or transfer assembly.)
