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?

Go to Step 2.

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: System voltage

Q. Is the check result normal?

Go to Step 4.

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-125 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-125 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?

Retest the system.

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: System voltage

Q. Is the check result normal?

Go to Step 6.

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?

Retest the system.

Repair the wiring harness.

Step 6. Voltage measurement at combination meter connector C-02 in order to power supply circuit to combination meter (IG1 power supply).

(1)Disconnect combination meter connector C-02, and measure at the wiring harness side.
(2)Turn the ignition switch to "ON" position.

(3)Measure the voltage between terminal 39 and earth.
OK: System voltage

Q. Is the check result normal?

Go to Step 8.

Go to Step 7.

Step 7. Check the wiring harness between combination meter connector C-02 (terminal 39) and ignition switch (IG1).

note

Also check junction block connector C-202 and C-205 for loose, corroded, or damaged terminals, or terminals pushed back in the connector. If 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 39) and ignition switch (IG1) in good condition?

Retest the system.

Repair the wiring harness.

Step 8. Resistance measurement at combination meter connector C-02 in order to the earth circuit to the combination meter.

(1)Disconnect combination meter connector C-02, and measure at the wiring harness side.

(2)Measure the resistance between terminal 1 and earth.
OK: Continuity exists (2 Ω or less)

(3)Measure the resistance between terminal 21 and earth.
OK: Continuity exists (2 Ω or less)

Q. Is the check result normal?

Go to Step 10.

Go to Step 9.

Step 9. Check the wiring harness between combination meter connector C-02 (terminals 1 and 21) and earth.

Q. Are the wiring harness between combination meter connector C-02 (terminals 1 and 21) and earth in good condition?

Retest the system.

Repair the wiring harness.

Step 10. Retest the system.

Q. Is the check result satisfactory?

	Intermittent Malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions .)

	Replace the combination meter.
