STEP 3. Check the wiring harness between 
combination meter connector C-04 (terminal 43) 
and fuel gauge unit connector D-15 (terminal 1) 
<2WD> or fuel pump and gauge unit (main) 
connector D-16 (terminal 2) <4WD>.

NOTE: 

Prior to the wiring harness inspection, check fuel 
gauge unit (sub) connector D-12, intermediate 
connector C-117, D-24, and repair if necessary.

Q: Is the wiring harness between fuel gauge unit 

connector D-15 (terminal 2) <2WD> and fuel pump 
and gauge unit connector D-16 (terminal 1) <4WD> 
and earth in good condition?

YES : 

Go to Step 7.

NO : 

Repair or replace the damaged 
component(s).

STEP 7. Retest the system.

Q: Is the fuel gauge normal?

YES : 

The procedure is complete. (If no

).

NO : 

Carry out the troubleshooting again.

STEP 8. Check the fuel gauge circuit.
(1) Disconnect D-15 <2WD> fuel gauge unit 

connector or D-16 <4WD> fuel pump and gauge 
unit (main) connector.

(2) Connect a test lamp (12 V 

−

 3.4 W) via special 

tool test harness (MB991219) between the wiring 
harness connector terminals 1 and 2.

(3) Turn the ignition switch to the "ON" position.

Q: Does the fuel gauge in the combination meter 

fluctuate about half of it full scale?

YES : 

Replace the fuel gauge unit.

NO : 

Go to Step 9.

STEP 9. Retest the system.

Q: Is the fuel gauge normal?

YES : 

The procedure is complete. (If no 

malfunctions are found in all steps, an

INSPECTION PROCEDURE 5: Engine Coolant Temperature Gauge does not Work. (the other meters 
work.) 

TECHNICAL DESCRIPTION (COMMENT)
If only the engine coolant temperature gauge does 
not operate, the combination meter, the wiring 
harness or its connector may be defective.

TROUBLESHOOTING HINTS

•

Malfunction of the engine coolant temperature 
gauge unit

•

The wiring harness or connectors may have 
loose, corroded, or damaged terminals, or 
terminals pushed back in the connector.

•

Malfunction of the combination meter.

DIAGNOSIS PROCEDURE 

STEP 1. Check the engine coolant temperature 
gauge circuit.
(1) Disconnect the B-109 engine coolant 

temperature gauge unit connector.

(2) Connect a test lamp (12 V 

−

 3.4 W to 12 V 

−

 7.0 

W) to the wiring harness side connector.

(3) Ignition switch: ON

Q: Does the test lamp illuminate?

YES : 

Go to Step 5.

NO : 

Go to Step 2.
