INSPECTION PROCEDURE 2: Power supply circuit.; INSPECTION PROCEDURE 3: Odometer and trip meter are not displayed.; INSPECTION PROCEDURE 4: No needle meters work.; INSPECTION PROCEDURE 5: When the ignition switch is turned to the ON position, the indicator and warning lights do not illuminate: Diagnosis
Required Special Tools:
- MB991223: Harness set
- MB992006: Extra Fine Probe
- STEP 1. Check combination meter connector C-04 for loose, corroded or damaged terminals, or terminals pushed back in the connector.
Q: Is combination meter connector C-04 in good condition?
- YES : Go to Step 2.
- NO : Repair or replace the component(s). Refer to HARNESS CONNECTOR INSPECTION . The combination meter works normally.
- STEP 2. Measure at combination meter connector C-04 in order to power supply circuit to combination meter (battery power supply).
- Disconnect combination meter connector C-04, and measure at the wiring harness side.
- Measure the voltage between terminal 10 and ground.
- The voltage should measure approximately 12 volts (battery positive voltage).
Q: Is the measured voltage approximately 12 volts (battery positive voltage)?
- YES : Go to Step 4.
- NO : Go to Step 3.
- STEP 3. Check the wiring harness between combination meter connector C-04 (terminal 10) and the battery.
- Check the power supply line for open circuit and short circuit.

NOTE: Also check intermediate connector C-24 for loose, corroded, or damaged terminals, or terminals pushed back in the connector. If intermediate connector C-24 is damaged, repair or replace. Refer to HARNESS CONNECTOR INSPECTION .Q: Is the wiring harness between combination meter connector C-04 (terminal 10) and the battery in good condition?
- YES : Retest the system.
- NO : Repair the wiring harness. Check that the combination meter is normally.
- STEP 4. Measure the voltage at combination meter connector C-04 in order to power supply circuit to combination meter (IG1 power supply).
- Disconnect combination meter connector C-04, and measure at the wiring harness side.
- Turn the ignition switch to "ON" position.
- Measure the voltage between terminal 11 and ground.
- The voltage should measure approximately 12 volts (battery positive voltage).
Q: Is the measured voltage approximately 12 volts (battery positive voltage)?
- YES : Go to Step 6.
- NO : Go to Step 5.
- STEP 5. Check the wiring harness between combination meter connector C-04 (terminal 11) and the ignition switch (IG1).
- Check the power supply line for open circuit and short circuit.

NOTE: Also check joint connector (2) C-01, junction block connector C-202 and C-215 for loose, corroded, or damaged terminals, or terminals pushed back in the connector. If inspecting joint connector (2) C-01 or junction block connector C-202 or C-215 is damaged, repair or replace. Refer to HARNESS CONNECTOR INSPECTION .Q: Is the wiring harness between combination meter connector C-04 (terminal 11) and the ignition switch (IG1) in good condition?
- YES : Refer to IGNITION SWITCH DIAGNOSIS .
- NO : Repair the wiring harness. Check that the combination meter is normally.
- STEP 6. Measure the resistance at combination meter connector C-04 in order to the ground circuit to the combination meter.
- Disconnect combination meter connector C-04, and measure at the wiring harness side.
- Measure the resistance value between terminal 1 and ground.
- The resistance should be 2 ohms or less.
Q: Is the measured resistance 2 ohms or less?
- YES : Go to Step 8.
- NO : Go to Step 7.
- STEP 7. Check the wiring harness between combination meter connector C-04 (terminal 1) and ground.
- Check the ground wire for open circuit.
Q: Is the wiring harness between combination meter connector C-04 (terminal 1) and ground in good condition?
- YES : Retest the system.
- NO : Repair the wiring harness. Check that the combination meter is normally.
- STEP 8. Retest the system.
Q: Is the check result satisfactory?
- YES : The procedure is complete. (If no malfunctions are found in all steps, an intermittent malfunction is suspected. Refer to HOW TO COPE WITH INTERMITTENT MALFUNCTION ).
- NO : Replace the combination meter.
