STEP 8. Check the wiring harness between combination 
meter connector C-101 (terminal 13) and fuel level sensor 
(sub) connector D-17 (terminal 2).

NOTE: Also check intermediate connectors C-28 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the 
connector. If intermediate connector C-28 is damaged, repair or 
replace the connector as described in GROUP 00E, Harness 
Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between combination meter 

connector C-101 (terminal 13) and fuel level sensor 
(sub) connector D-17 (terminal 2) in good condition?
YES : 
Go to Step 9.
NO :  Repair the wiring harness. The range to empty display 

should now operate normally.

STEP 9. Check fuel pump module connector D-18 and fuel 
level sensor (sub) connector D-17 for loose, corroded or 
damaged terminals, or terminals pushed back in the 
connector.
Q: Is fuel pump module connector D-18 and fuel level 

sensor (sub) connector D-17 in good condition?
YES : 
Go to Step 10.
NO :  Repair or replace the component(s). Refer to GROUP 

00E, Harness Connector Inspection 

P.00E-2

. The 

range to empty display should now operate normally.

STEP 10. Check the wiring harness between fuel pump 
module connector D-18 (terminal 2) and fuel level sensor 
(sub) connector D-17 (terminal 1).
Q: Is the wiring harness between fuel pump module 

connector D-18 (terminal 2) and fuel level sensor (sub) 
connector D-17 (terminal 1) in good condition?
YES : 
Go to Step 11.
NO :  Repair the wiring harness. The range to empty display 

should now operate normally.

STEP11. Retest the system.
 Check that the range to empty display works normally.

Q: Is the Range to empty display reading normal?

YES : The procedure is complete. (If no malfunctions are 

found in all steps, an intermittent malfunction is 
suspected. Refer to GROUP 00, How to Use 
Troubleshooting/Inspection Service Points 

− How to 

Cope with Intermittent Malfunction 

P.00-14

).

NO :  Replace the combination meter.

INSPECTION PROCEDURE 3: Total fuel used does not operate (increase). INSPECTION PROCEDURE 
4: Total fuel used diplays abnormally low/high value. INSPECTION PROCEDURE 5: Average fuel 
always displays "0.1" litres/ 100km. INSPECTION PROCEDURE 6: Average fuel displays abnormally 
low/high value.INSPECTION PROCEDURE 7: Instant fuel always displays "0.1" litres/ 100km. 
INJECTOR PROCEDURE 8: Instant fuel displays abnormally low/high result.

.

CIRCUIT OPERATION

• The injector power is supplied from the MPI relay 

(terminal No. 4).

• The ENGINE-ECU controls the injectors by turn-

ing the power transistor in the ECU "ON" and 
"OFF".

• The injectors sends a signal to the Engine-ECU 

which in turn sends a signal to the combination 
meter via the CAN bus line (every 0.5 of a sec-
ond).

.

TECHNICAL DESCRIPTION

• The amount of fuel injected by the injectors is 

controlled by the amount of continuity time the 
coil is grounded by the ECU.

• A surge voltage is generated when the injectors 

are driven and the current flowing to the injector 
coil is shut off.

• The ENGINE-ECU checks this surge voltage.
