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 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

1. 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.

   3. 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.

   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.

4. STEP 4. Measure the voltage at combination meter connector C-04 in order to power supply circuit to combination meter (IG1 power supply). 
   1. Disconnect combination meter connector C-04, and measure at the wiring harness side.
   2. Turn the ignition switch to "ON" position.

   3. 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.

   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:  Retest the system.

   NO:  Repair the wiring harness. Check that the combination meter is normally.

   2. 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.
