Inspection Procedure 1: Power Supply Circuit System Check.
Inspection Procedure 2: Odometer and Trip Meter is not Displayed.
Inspection Procedure 3: All the Needle Meters do not Work.
Inspection Procedure 4: If the Ignition Switch is Turned to the ON Position, the Indicator and Warning Lamps do not Illuminate.






COMMENTS ON TROUBLE SYMPTOM


If the odometer and trip meter is not displayed or all the meter needles doesn’t move, power supply to the combination meter, or the combination meter itself may be defective.

PROBABLE CAUSES



  • Damaged harness wires and connectors
  • Malfunction of the combination meter

DIAGNOSIS PROCEDURE


STEP 1. Connector check: Combination meter connector C-111, C-112 and C-113.




Q. Is the check result normal?

Go to Step 2.

Repair the defective connector.

STEP 2. Voltage measurement at combination meter connector C-112.




Disconnect the connector, and measure at the wiring harness side.


  • Ignition switch: "LOCK" (OFF) position.
  • Voltage between combination meter connector C-112 terminal No.42 and body earth.
OK: System voltage

Q. Is the check result normal?

Go to Step 4.

Go to Step 3.

STEP 3. Check the harness wire between the battery (fusible link No.20) and combination meter connector C-112 (terminal No.42).









note Prior to the wiring harness inspection, check joint connector C-132 and junction block connectors C-209 and C-213, and repair if necessary.

Q. Is the wiring harness between the battery (fusible link No.20) and combination meter connector C-112 (terminal No.42) in good condition?

Retest the system.

Repair the wiring harness.

STEP 4. Voltage measurement at combination meter connector C-112.




Disconnect the connector, and measure at the wiring harness side.


  • Ignition switch: ON position.
  • Voltage between combination meter connector C-112 terminal No.36 and body earth.
OK: System voltage

Q. Is the check result normal?

Go to Step 6

Go to Step 5

STEP 5. Check the harness wire between the ignition switch (IG1) and combination meter connector C-112 (terminal No.36).








note Prior to the wiring harness inspection, check joint connector C-132 and junction block connectors C-207 and C-209, and repair if necessary.

Q. Is the wiring harness between the ignition switch (IG1) and combination meter connector C-112 (terminal No.36) in good condition?

Retest the system.

Repair the wiring harness.

STEP 6. Resistance measurement at combination meter connector C-111 and C-113.






  • Disconnect the connector, and measure at the wiring harness side.
  • Resistance between combination meter connector C-113 terminal No.13 and body earth.
OK: Continuity exists (2 Ω or less)


  • Resistance between combination meter connector C-111 terminal No.57 and body earth.
OK: Continuity exists (2 Ω or less)

Q. Is the check result normal?

Go to Step 8

Go to Step 7

STEP 7. Check the harness between combination meter connector C-111 (terminal No.57), C-113 (terminal No.13) and body earth.




Q. Is the wiring harness between the combination meter connector C-111 (terminal No.57), C-113 (terminal No.13) and body earth in good condition?

Retest the system.

Repair the wiring harness.

STEP 8. Retest the system.


Q. Is the check result normal?

The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
Replace the combination meter.
