		Test results
1	MODE PARAMETERS CHECK	All OK	Problems encountered	Operation
	Select the following control unit at the diagnostic equipment: Marelli Diesel Injection 6F3 EOBD CAN (EP engine 1.3 JTD).Check the value of the following parameters:- Battery voltage    See Test 5530BB BATTERY VOLTAGE CHECK- Accelerator position 1 AD/C- Accelerator 2 position AD/C    See Test 1068AC ACCELERATOR PEDAL CHECKS- Coolant temperature    See Test 1060OE ENGINE COOLANT TEMPERATURE SENSOR OPERATION CHECK- Diesel temperature    See Test 1060EA DIESEL TEMPERATURE CHECK	Move on to Step 2
2	INTAKE AND SUPPLY CIRCUITS CHECK	All OK	Problems encountered	Operation
	Check that the air intake/vacuum circuit is working properly    See Test 1048OA AIR INTAKE/VACUUM CIRCUIT CHECKCheck the condition of the fuel supply circuit and make sure that it is working properly    See Test 1040OA FUEL SUPPLY CIRCUIT CHECK	Move on to Step 3
3	CONFIGURATION TESTS	All OK	Problems encountered	Operation
	Select the following control unit at the diagnostic equipment: Marelli Diesel Injection 6F3 EOBD CAN (EP engine 1.3 JTD).Check in the Configurations section whether the replacement of any of the following components is followed by their subsequent configuration:- injectorIn this case, carry out the configuration, checking that the outcome is positive	Move on to Step 6	The outcome of the configuration is not positive	Move on to Step 4
4	ERROR CHECK	All OK	Problems encountered	Operation
	Check whether any of the following errors are present using the diagnostic equipment:- P1301- U0001- U0426- U1700	Move on to Step 6	1. Error P1301 is present2. Error U0001 is present3. Error U0426 is present4. Error U1700 is present	1. Move on to Step 52. Continue as indicated    See table U0001 CAN line error3. Memorise the CODE. If it is not possible, replace the engine control unit    Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - R.R 4. Continue as indicated    See table U1700 CAN network (NCM - NBC)
5	IMA CLASSIFICATION	All OK	Problems encountered	Operation
	In the Configurations section on the diagnostic tester, rerun the IMA classification and ensure it is successful	End of diagnosis	The classification is unsuccessful	Replace the engine management control unit    Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - R.R
6	MODE PARAMETERS CHECK	All OK	Problems encountered	Operation
	Select the following control unit at the diagnostic equipment: Marelli Diesel Injection 6F3 EOBD CAN (EP engine 1.3 JTD).Check the value of the following parameters:- Measured Diesel pressure    See Test 1060GH DIESEL PRESSURE CHECK- Pressure regulator opening (MPROP)    See Test 1060GR CHECK OPERATION OF FUEL PRESSURE SENSOR ON RAIL- Engine rpm    See Test 1060GI CHECK ENGINE SPEED	End of diagnosis
