2427551 - K44 Data not available yet

The fuel consumption indiator in the display (one of the TRIP COMPUTER module displays) does not work with te ignition ON.

The display shows two types of fuel consumption, instantaneous and average. The fuel consumption figures are processed by the instrument panel node on the basis of the information received from the body computer node (distance) and from the engine management node (litres consumed), made available to the instrument panel node via the B-CAN and the C-CAN, respectively.

If there is no speed information (from the Brake Node) or instantaneous fuel consumption (from the Engine Management Node) the consumption figure will be replaced by '----'

0	PRELIMINARY CHECKS	All OK	Problems met	Operation
		Results of the tests
	Speak to the customer to check that the TRIP functions have not just been reset	Continue to Step 1	One of the TRIP COMPUTER functions has been reset	The information displayed will be '----' until a stretch of road sufficient to evaluate the consumption is travelled along: if the value is not displayed after a few kilometresContinue to Step 1
1	CAN CHECKS	All OK	Problems met	Operation
	Connect the EXAMINER diagnostic equipment and check the CAN NETWORK INFORMATION: For inactive control units For control units with errors For control units with CAN errors	Continue to Step 2	Presence of fault in the CAN	Continue as instructed by the tester
		Continue to Step 2	Impossible to converse with the Body Computer	Continue to Step 9
2	CHECK WITH DIAGNOSTIC EQUIPMENT	All OK	Problems met	Operation

		Continue to Step 3	Presence of C-CAN faults	Continue to Step 11
3	CHECK WITH DIAGNOSTIC EQUIPMENT	All OK	Problems met	Operation
	Keeping the diagnostic equipment connected, check for the following at the ENGINE MANAGEMENT NODE: System/component faults CAN faults	Continue to Step 4	System/component faults	Continue as instructed by the tester
		Continue to Step 4	Presence of C-CAN faults	Continue to Step 11
4	CHECK WITH DIAGNOSTIC EQUIPMENT	All OK	Problems met	Operation
	Keeping the diagnostic equipment connected, check at the INSTRUMENT PANEL NODE: System/component faults CAN faults	Continue to Step 12	System/component faults	Continue as instructed by the tester
		Continue to Step 12	Presence of C-CAN faults	Continue to Step 11
5	CHECK WITH ACTIVE DIAGNOSIS	All OK	Problems met	Operation
	With the Examiner in the Instrument Panel Node ambient, check, in active diagnosis, that all the segments in the LCD module are correctly activated	Continue to Step 8	One or more segments are not activated	Replace the instrument panel Op. 5560B11
		Continue to Step 8	Impossible to converse with the instrument panel	Continue to Step 6
6	ELECTRIC POWER SUPPLY CHECK	All OK	Problems met	Operation
	Check that the Instrument Panel Node electrical power supply is correct	Continue to Step 7	Positive and/or earth electrical power supply faulty	Replace the component involved (if a fuse is involved, search for the cause of the problem)
7	CHECK ELECTRICAL CONNECTIONS	All OK	Problems met	Operation
	Check the electrical connections between the Body Computer and the Instrument Panel, in particular that each individual pin is correctly connected	Continue to Step 5	Electrical connections not working	Restore damaged electrical connections.
8	CHECK WITH DIAGNOSTIC EQUIPMENT	All OK	Problems met	Operation
	Using the Examiner check, in the Body Computer Node ambient, that there are no errors	Continue to Step 11	Impossible to connect with the Body Computer control unit	Continue to Step 9
		Continue to Step 11	There are errors	Continue in accordance with the instructions for the diagnostic equipment
9	ELECTRIC POWER SUPPLY CHECK	All OK	Problems met	Operation
	Check that the Body Computer Node electrical power supply is correct.	Continue to Step 10	Positive and/or earth electrical power supply fault.	Replace the defective component (if a fuse is involved, search for the cause of the problem).
10	CHECK WITH DIAGNOSTIC EQUIPMENT	All OK	Problems met	Operation
	Using the Examiner, check the possibility of connecting with the Body Computer Node.	Continue to Step 8	Impossible to connect with the Body Computer control unit.	Replace the Body Computer Op. 5505A32
11	CHECK ON CORRECT OPERATION	All OK	Problems met	Operation
	Check that the fault is no longer present	End of diagnosis	The fault persists	Replace the Body Computer Op. 5505A32
