INSPECTION PROCEDURE 2: Power Supply Circuit. INSPECTION PROCEDURE 3: Odometer and Trip 
meter are not displayed. INSPECTION PROCEDURE 4: All the needle meters do not work. 
INSPECTION PROCEDURE 5: When the ignition switch turned to the ON position, the indicator and 
warning lamps do not illuminate.

COMMENTS ON TROUBLE SYMPTOM

If the odometer and trip meter are not displayed or all 
meter needles don't move, power supply and earth 

system to the combination meter, or the combination 
meter itself may be defective.

POSSIBLE CAUSES

• Damaged harness wires and connectors

• Malfunction of combination meter

DIAGNOSTIC PROCEDURE

Step 1. Connector check: Combination meter 
connector C-02.

Q: Is combination meter connector C-02 in good 

condition?

YES : 

Go to Step 2.

NO : 

Repair the defective connector.

Step 2. Voltage measurement at combination 
meter connector C-02 in order to power supply 
circuit to combination meter (battery power 
supply).

(1) Disconnect combination meter connector C-02, 

and measure at the wiring harness side.

(2) Turn the ignition switch to "LOCK" (OFF) position.

(3) Measure the voltage between terminal 40 and 

earth.

OK: Battery voltage

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Go to Step 3.

Step 3. Check the wiring harness between 
combination meter connector C-02 (terminal 40) 
and battery (fusible link No.26).

NOTE: Also check joint connector C-32 <LH drive 
vehicles> or C-31 <RH drive vehicles> and 
intermediate connector C-128 for loose, corroded, or 
damaged terminals, or terminals pushed back in the 
connector. If joint connector C-32 <LH drive 
vehicles> or C-31 <RH drive vehicles> or 
intermediate connector C-128 is damaged, repair or 

replace the connector.

Q: Is the wiring harness between combination meter 

connector C-02 (terminal 40) and battery (fusible 
link No.26) in good condition?

YES : 

Retest the system.

NO : 

Repair the wiring harness.

Step 4. Voltage measurement at combination 
meter connector C-02 in order to power supply 
circuit to combination meter (ACC power 
supply).

(1) Disconnect combination meter connector C-02, 

and measure at the wiring harness side.

(2) Turn the ignition switch to "ACC" position.

(3) Measure the voltage between terminal 20 and 

earth. 

OK: Battery voltage

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Go to Step 5.

Step 5. Check the wiring harness between 
combination meter connector C-02 (terminal 20) 
and ignition switch (ACC).

NOTE: 

Also check joint connector C-01, junction block 
connector C-202 and C-205 for loose, corroded, or 
damaged terminals, or terminals pushed back in the 
connector. If joint connector C-01 or junction block 
connector C-202 and C-205 is damaged, repair or 
replace the connector.

Q: Is the wiring harness between combination meter 

connector C-02 (terminal 20) and ignition switch 
(ACC) in good condition?
