DIAGNOSIS PROCEDURE

Step 1. Connector check: Fuel tank pump and 
gauge unit assembly connector D-15.

Q: Is fuel tank pump and gauge unit assembly 

connector C-02 in good condition?

YES : 

Go to Step 2.

NO : 

Repair the connector, and then go to Step 
11.

Step 2. Check the fuel gauge circuit.

(1) Disconnect fuel tank pump and gauge unit 

assembly connector D-15.

(2) Use special tool MB991219 to connect a test 

lamp (12 V - 3.4 W) between the wiring harness 

connector terminals 1 and 2.

(3) Turn the Ignition switch to "ON" position.
(4) Check if the test lamp illuminates.

OK: Illuminates

Q: Is the check result satisfactory?

YES : 

Go to Step 8.

NO : 

Go to Step 3.

Step 3. Resistance measurement at fuel tank 
pump and gauge unit assembly connector D-15 
to check the earth circuit to the fuel tank pump 
and gauge unit assembly.

(1) Disconnect fuel tank pump and gauge unit 

assembly connector D-15, and measure at the 
wiring harness side.

(2) Turn the Ignition switch to "LOCK" (OFF) 

position.

(3) Disconnect the negative battery terminal.

(4) Measure the resistance value between terminal 1 

and earth.

OK: 2 ohms or less

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Go to Step 4.

Step 4. Check the wiring harness between fuel 
tank pump and gauge unit assembly connector 
D-15 (terminal 1) and earth.

NOTE: 

Also check intermediate connector D-28, C-16 for 
loose, corroded, or damaged terminals, or terminals 
pushed back in the connector. If intermediate 
connector D-28, C-16 are damaged, repair or 
replace the connector.

Q: Is the wiring harness between fuel tank pump and 

gauge unit assembly connector D-15 (terminal 1) 
and earth in good condition?

YES : 

Go to Step 11.

NO : 

Repair the harness, and then go to Step 11.

Step 5. Connector check: Combination meter 
connector C-02 and fuel tank gauge unit 
connector D-07.

Q: Is combination meter connector C-02 and fuel tank 

gauge unit connector D-07 in good condition?

YES : 

Go to Step 6.

NO : 

Repair the connector, and then go to Step 
10.
