DTC		CONSULT screen terms		DTC detection condition
DTC		(Trouble diagnosis content)	[Malfunction type]	DTC detection condition
B1F72	00	Heated steering wheel output sig [The output for the steering wheel heater voltage supply and the 'steering wheel' vibration motor has a malfunction.]	[NO SUBTYPE INFORMATION]	1	Diagnosis condition	Ignition switch ON battery voltage is between 7.2 - 16.2V Operational voltage in range between 7.5 - 17.5V +-10%
					Signal (terminal)	-
					Threshold	2 seconds after the shut down of the steering wheel vibration there are still flowing more than 0.5 A to power the steering actuators.
					Diagnosis delay time	2 seconds
B1F72	00	Heated steering wheel output sig [The output for the steering wheel heater voltage supply and the 'steering wheel' vibration motor has a malfunction.]	[NO SUBTYPE INFORMATION]	2	Diagnosis condition	Ignition switch ON battery voltage is between 7.2 - 16.2V Operational voltage in range between 7.5 - 17.5V +-10%
					Signal (terminal)	-
					Threshold	It is flowing more than 8 A to power the steering actuators.
					Diagnosis delay time	0.05 seconds
B1F72	00	Heated steering wheel output sig [The output for the steering wheel heater voltage supply and the 'steering wheel' vibration motor has a malfunction.]	[NO SUBTYPE INFORMATION]	3	Diagnosis condition	Ignition switch ON battery voltage is between 7.2 - 16.2V Operational voltage in range between 7.5 - 17.5V +-10%
					Signal (terminal)	-
					Threshold	Depending on the environment temperature and the SLA-consumer current a prediction of the WFK-Temperature will be calculated. If this temperature exceeds 90°C, then the current supply will be shut down.
					Diagnosis delay time	Immediately

					Signal (terminal)	-
					Threshold	Internal calibration value is not plausible.
					Diagnosis delay time	Immediately
B1F72	00	Heated steering wheel output sig [The output for the steering wheel heater voltage supply and the 'steering wheel' vibration motor has a malfunction.]	[NO SUBTYPE INFORMATION]	5	Diagnosis condition	Ignition switch ON battery voltage is between 7.2 - 16.2V Operational voltage in range between 7.5 - 17.5V +-10%
					Signal (terminal)	-
					Threshold	CRC (cyclic redundancy check) of the internal calibration value is not valid.
					Diagnosis delay time	Immediately

					Signal (terminal)	-
					Threshold	The internal calibration value cannot be punctually loaded.
					Diagnosis delay time	1 second
B1F72	00	Heated steering wheel output sig [The output for the steering wheel heater voltage supply and the 'steering wheel' vibration motor has a malfunction.]	[NO SUBTYPE INFORMATION]	7	Diagnosis condition	Ignition switch ON battery voltage is between 7.2 - 16.2V Operational voltage in range between 7.5 - 17.5V +-10%
					Signal (terminal)	-
					Threshold	The hardware to measure the current could not be requested.
					Diagnosis delay time	Immediately
