INSPECTION PROCEDURE 11: Combination meter does not work (the instruments do not work). <L.H. drive vehicles>
TECHNICAL DESCRIPTION (COMMENT) The cause is thought to be malfunction of the power, earth circuitry or combination meter.
TROUBLESHOOTING HINTS Malfunction of the combination meter Damaged wiring harness or connectors
| DIAGNOSIS PROCEDURE
| STEP 1. Measure the voltage at combination meter connector C-04 in order to check the battery circuit of power supply system to the combination meter. Disconnect the combination meter connector C-04 and measure the voltage at combination meter connector C-04 component side. Measure the voltage between terminal 35 and earth. OK: Battery positive voltage Q: IS the check result normal? YES: Go to Step 4. NO: Go to Step 2.
| STEP 2. Connector check: combination meter connector C-04. Q: Is combination meter connector C-04 in good condition? YES: Go to Step 3. NO: Repair or replace the connector. Check to see that all meters operate.
| STEP 3. Check the wiring harness between combination meter connector C-04 (terminal 35) and battery. NOTE: Prior to the wiring harness inspection, check intermediate connectors C-116 and joint connector (3) C-02, and repair if necessary. Q: Are the wiring harness between combination meter connector C-04 (terminal 35) and battery in good condition? YES: There is no action to be taken. NO: Repair or replace the wiring harness. Check to see that all meters operate.
| STEP 4. Measure the voltage at combination meter connector C-04 to check the battery circuit of power supply system to the combination meter. Measure at combination meter connector C-04 without disconnecting the connector. Turn the ignition switch to "ON" position. Measure the voltage between terminal 42 and earth. OK: Battery positive voltage Q: Is the check result normal? YES: Go to Step 7. NO: Go to Step 5.
| STEP 5. Connector check: Combination meter connector C-04. Q: Is combination meter connector C-04 in good condition? YES: Go to Step 6. NO: Repair or replace the connector. Check to see that all meters operate.
| STEP 6. Check the wiring harness between combination meter connector C-04 (terminal 42) and ignition switch (IG1). NOTE: Prior to the wiring harness inspection, check Junction block connectors C-203 and C-205, and repair if necessary. Q: Are the wiring harness between combination meter connector C-04 (terminal 42) and ignition switch (IG1) in good condition? YES: There is no action to be taken. NO: Repair or replace the wiring harness. Check to see that all meters operate.
| STEP 7. Measure the resistance at combination meter connector C-04 to check the earth circuit to the combination meter. Disconnect the combination meter connector C-04 and measure the resistance at combination meter connector C-04. Measure the resistance between terminal 40 and earth. OK: 2 ohms or less Measure the resistance between terminal 41 and earth. OK: 2 ohms or less Q: Is the check result normal? YES: Repair or replace the connector. NO: Go to Step 8.
| STEP 8. Connector check: Combination meter connector C-04 for damage. Q: Is combination meter connector C-04 in good condition? YES: Go to Step 9. NO: Repair or replace the wiring harness. Check to see that all meters operate.
| STEP 9. Check the wiring harness between combination meter connector C-04 (terminal 40 and 41) and earth. Q: Are the wiring harness between combination meter connector C-04 (terminal 40 and 41) and earth in good condition? YES: This procedure is complete. NO: Repair or replace the wiring harness. Check to see that all meters operate.
