			Test results
1	COMPONENT CONCERNED	CONNECTIONS CHECK	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Connectors	Check that all the connectors are correctly attached to the counterparts and that the CPA, if there are any, are closed (see fig. 1) (The figures can be viewed in the diagnosis in text format).	Go to Step 2	There are loose connections or breaks in continuity	Restore the correct connections or the correct continuity. Close the relative open CPA
2	COMPONENT CONCERNED	CHECK THE EARTH RING TERMINALS	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Earth ring terminals	Check that the earth ring terminals are attached and the nuts tightened. Check for the yellow point indicating the torque is closed	Go to Step 3	Earth rings not properly tightened	Tighten the nuts with the dynamometer spanner, entering indication that the torque is closed
3	COMPONENT CONCERNED	CHECK TERMINAL ATTACHMENT	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Terminals	Check the continuity of the internal wiring to the tabs. Check that the male tabs are aligned (see fig. 2) (The figures can be viewed in the diagnosis in text format). Using the probe kit, check the continuity or presence of loose connections inside the female tabs	Go to Step 4	1.Male tabs not aligned 2. Female tabs not correctly connected	1. Push the wire into the cavity until the terminals realign. 2. Perform a traction test to be sure that they do not move (primary lock damaged). In case they move, replace the wire. In case they do not move, repeat the diagnosis to confirm that the fault has been eliminated
4	COMPONENT CONCERNED	VISUAL CHECK ON CABLE BUNDLE WIRE	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Cable bundle wire	Check that there are no apparent cuts on the cable bundle, sheared wires or electrical jumper connections (see fig. 3) (The figures can be viewed in the diagnosis in text format).	Go to Step 5	Wiring with signs of cuts on the cable bundle, sheared cables or electrical jumpers	Replace the wiring
5	COMPONENT CONCERNED	CHECK CABLE BUNDLE WIRE	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Cable bundle wire	Check the continuity and insulation of the wiring with a tester, being careful not to insert the points into the terminals. Also check the electrical continuity on the operation involved in the fault by slightly moving the part of the wire concerned.	Go to Step 6	Interruption in the continuity or incorrect wiring insulation	Restore the correct continuity or insulation of the wiring. Also check that the involved circuit terminals are correctly positioned and that there are no inversions on them. IN the case of terminal inversions, restore the correct positioning and repeat the diagnosis. Replace the wiring if the fault is reconfirmed
6	COMPONENT CONCERNED	FOREIGN BODIES CHECK	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Connectors	Disconnect all the connectors involved in the fault on the entire connection line concerned and check for foreign bodies, grease or dust (see fig. 4)	Go to Step 7	Presence of foreign bodies, grease or dust	Remove the foreign bodies or clean the connection. Repeat the diagnosis to confirm the elimination of the fault
7	COMPONENT CONCERNED	VISUAL CHECK OF TERMINALS AND UTILITIES CONNECTORS	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Terminals and utilities connectors	Check that the terminal wiring connections are not deformed (see fig. 5) (The figures can be viewed in the diagnosis in text format). Also check that the utilities connectors the terminals are connected to are not deformed	Go to Step 8	Presence of deformed terminals	Replace the wiring if there are deformations on the terminals. Replace the utilities that show deformities on the connectors
8	COMPONENT CONCERNED	CHECK THE ENGINE UTILITY OPERATION	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	E utilities	Check the engine utilities connected to the wiring are working properly	End of diagnosis	At least one of the utilities is not working properly	Replace the improperly functioning utilities
