DISPLAY DOES NOT SHOW RANGE ON TRIP MODULE

With the key ON, the fuel consumption gauge on the display (one of the displays on the TRIP COMPUTER module) is not operational.

The fuel consumption readings are processed by the instrument panel node on the basis of information received from the body computer node (mileage) and the engine control node (litre of fuel consumed) made available to the instrument panel node via the B-CAN and C-CAN networks respectively. This data is then adjusted proportionally according to the tank capacity programmed at the end of the line.

In the absence of speed information (from the Brake Node) or instantaneous fuel consumption data (from the Engine Control Node), the fuel consumption data will be replaced by the reading "----"

0	PRELIMINARY CHECKS	All OK	Problems encountered	Operation
		Test results
	Interview the customer to check that the TRIP function has not been recently reset	Move on to Step 1	The display reading will be "----" until sufficient distance has been covered to allow fuel consumption to be evaluated: if the figure is not displayed after a few kilometres this means that one of the TRIP COMPUTER functions has been reset	Move on to Step 1
1	CAN CHECKS	All OK	Problems encountered	Operation
	Connect an EXAMINER and check the following on CAN NETWORK INFORMATION: No control units inactive No faulty control units No control units with faulty CAN line	Move on to Step 2	Fault on CAN network	Continue following the instructions given by the diagnostic equipment
		Move on to Step 2	Communication with the Body Computer impossible	Move on to Step 9
2	CHECK USING DIAGNOSTIC EQUIPMENT.	All OK	Problems encountered	Operation
	Keeping the diagnostic instrument connected, check the following on the BRAKE NODE: No system/component errors No CAN faults	Move on to Step 3	System/components faulty	Continue following the instructions given by the diagnostic equipment
		Move on to Step 3	Fault on C-CAN network	Move on to Step 11
3	CHECK USING DIAGNOSTIC EQUIPMENT	All OK	Problems encountered	Operation
	Keeping the diagnostic instrument connected, check the following on the ENGINE CONTROL NODE: No system/component errors No CAN faults	Move on to Step 4	System/components faulty	Continue following the instructions given by the diagnostic equipment
		Move on to Step 4	Fault on C-CAN network	Move on to Step 11
4	CHECK USING DIAGNOSTIC EQUIPMENT	All OK	Problems encountered	Operation
	Keeping the diagnostic instrument connected, check the following on the INSTRUMENT PANEL NODE: No system/component errors No CAN faults	Move on to Step 12	System/components faulty	Continue following the instructions given by the diagnostic equipment
		Move on to Step 12	Fault on C-CAN network	Move on to Step 11
5	ACTIVE DIAGNOSIS CHECK	All OK	Problems encountered	Operation
	With the Examiner in Instrument Panel Node mode check that all segments of the LCD module are correctly activated in Active Diagnosis.	Move on to Step 8	One or more segments do not activate	Replace the instrument panel Op. 5560B10 CONTROL PANEL - R+R
		Move on to Step 8	Communication with the instrument panel impossible	Move on to Step 6
6	ELECTRICAL POWER SUPPLY CHECK	All OK	Problems encountered	Operation
	Check the electricity supply to the Instrument Panel Node is correct.	Move on to Step 7	Fault in positive electrical supply and/or earth	Replace defective component (in the case of a fuse, find out what caused it to blow)
7	ELECTRICAL CONNECTIONS CHECK	All OK	Problems encountered	Operation
	Check the wiring between the Body Computer and the Instrument Panel. In particular, check that each individual pin is properly connected.	Move on to Step 5	Electrical connections not operational	Renew the damaged electrical connections
8	CHECK USING DIAGNOSTIC EQUIPMENT	All OK	Problems encountered	Operation
	Using an Examiner check, in Body Computer Node mode, that there are no errors.	Move on to Step 11	Impossible to connect to the Body Computer control unit	Move on to Step 9
		Move on to Step 11	Presence of errors	Continue by following the instructions on the diagnostic instrument
9	ELECTRICAL POWER SUPPLY CHECK	All OK	Problems encountered	Operation
	Check the electricity supply to the Body Computer Node is correct.	Move on to Step 10	Fault in positive electrical supply and/or earth.	Replace defective component (in the case of a fuse, find out what caused it to blow).
10	CHECK USING DIAGNOSTIC EQUIPMENT	All OK	Problems encountered	Operation
	Use an Examiner to check the possibility of connection to the Body Computer Node	Move on to Step 8	Impossible to connect to the Body Computer control unit.	Replace Body Computer Op. 5505A35 MAIN BODY COMPUTER/JUNCTION UNIT - R.R.
11	CORRECT OPERATION CHECK	All OK	Problems encountered	Operation
	Check that the fault is no longer present	End of diagnosis	The fault persists	Replace Body Computer Op. 5505A35 MAIN BODY COMPUTER/JUNCTION UNIT - R.R.
12	CORRECT OPERATION CHECK	All OK	Problems encountered	Operation
	Check that the fault is no longer present	End of diagnosis	Fault persists	Replace the instrument panel Op. 5560B10 CONTROL PANEL - R+R
