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 test lamp illuminate?

YES : 

Go to Step 7.

NO : 

Go to Step 2.

STEP 2. Connector check: Combination meter 
connector C-113 and fuel gauge unit connector 
F-09.

Q: Is combination meter connector C-113 and fuel 

gauge unit connector F-09 in good condition?
YES : 

Go to Step 3.

NO : 

Repair or replace the damaged 
component(s). 

STEP 3. Check the wiring harness between 
combination meter connector C-113 (terminal 22) 
and fuel gauge unit connector F-09 (terminal 1).
Check the input lines for open circuit and short cir-
cuit.

NOTE: 

Prior to the wiring harness inspection, check interme-
diate connector C-30 and repair if necessary.

Q: Is the wiring harness between combination meter 

connector C-113 (terminal 22) and fuel gauge unit 
connector F-09 (terminal 1) in good condition?

YES : 

Go to Step 4.

NO : 

Repair or replace the damaged 
component(s). Then go to Step 4.

STEP 4. Retest the system.

Q: Is the fuel gauge 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 Cope with 
Intermittent Malfunction ).

NO : 

Go to Step 5.

STEP 5. Check the wiring harness between fuel 
gauge unit connector F-09 (terminal 2) and earth.
Check the earth wires for open circuit.

Q: Is the wiring harness between fuel gauge unit 

connector F-09 (terminal 2) and earth in good 
condition?

YES : 

Go to Step 6.

NO : 

Repair or replace the damaged 
component(s).

STEP 6. Retest the system.

Q: Is the fuel gauge 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 Cope with 
Intermittent Malfunction ).

NO : 

Carry out the troubleshooting again.

STEP 7. Check the fuel gauge unit.
Refer to 

P.54A-88

.

Q: Is the fuel gauge normal?

YES : 

Go to Step 8.

NO : 

Replace the fuel gauge unit.

STEP 8. Retest the system.

Q: Is the fuel gauge 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 Cope with 
Intermittent Malfunction ).

NO : 

Replace combination meter.

Inspection Procedure 8: Engine coolant temperature gauge does not work (Other meters work).

COMMENTS ON TROUBLE SYMPTOM
If only the engine coolant temperature gauge does 
not operate, the engine ECU system, the combina-
tion meter, the wiring harness or its connector may 
be defective.

PROBABLE CAUSES

• Damaged harness wires and connectors

• Malfunction of the engine coolant temperature 

gauge unit

• Malfunction of combination meter

DIAGNOSIS PROCEDURE

STEP 1. Check the engine coolant temperature 
gauge circuit.

(1) Disconnect the A-108 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.
