0	PRELIMINARY CHECKS	All OK	Problems met	Operation
		Results of the tests
	First check: the condition of the air filter leaks from intake manifolds after the compressor	Continue to Step 1	Filter element dirty or damaged	Replace the filter element Op. 1048A14
		Continue to Step 1	Leaks from intake manifolds	Renew the seal
1	CHECK WITH DIAGNOSTIC EQUIPMENT	All OK	Problems met	Operation
	Connect an Examiner tester to the tester connection and check the engine control node: for faults in error mode; for plausibility of all parameters in parameter mode; Check that the preheating system is working properly by carrying out active diagnosis	Continue to Step 2	Presence of one of the following errors: P0101, P1102	Continue to Step 2
			Presence of error P0400	Continue to Step 4
			An error is detected in the control unit	Continue following the instructions for the diagnostic equipment
			Unreliable parameters	Continue following the instructions for the diagnostic equipment
