	Activation of malfunction indicator lamp for engine diagnosis (EURO3/4) or CHECK ENGINE (MIL)	after two successive driving cycles with faults
3	Frequency of the test	continuous
4	Checked signal or status	Duty cycle for PWM-solenoid activation
5	Fault setting conditions	Duty cycle less than 5 %
	Lower limit	Duty cycle greater than 94 %
	Upper limit	approx. 1 s
	Test duration
6		Faults (line interruption and short circuit) are detected by the ETC control module and sent via the CAN data bus to the ME-SFI control module. The faults are stored and the malfunction indicator lamp is activated by the ME-SFI control module. Also read out ETC diagnostic trouble code memory, fault code 5.
