Inspection Procedure 6: The multi information display screen cannot be changed with the operation of the meter information switch: Diagnosis

Required Special Tools: 

• MB991223: Harness Set
• MB992006: Extra Fine Probe

1. STEP 1. Using scan tool MB991958, read the combination meter diagnostic trouble code. 

   Check if DTC is set in the combination meter.

   CAUTION: To prevent damage to scan tool MB991958, always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool MB991958.
   1. Connect scan tool MB991958. Refer to DIAGNOSIS  ."
   2. Turn the ignition switch to the "ON" position.
   3. Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
   4. Check if DTC is set.

   Q: Is the DTC set? 

   YES  : Troubleshoot the combination meter (Refer to DIAGNOSTIC TROUBLE CODE CHART  ).

   NO  : Go to Step 2.

2. STEP 2. Check meter information switch connector C-34 for loose, corroded or damaged terminals, or terminals pushed back in the connector. 

   Q: Is meter information switch connector C-34 in good condition? 

   YES  : Go to Step 3.

   NO  : Repair the connector.

3. STEP 3. Check the meter information switch. 

   Check the meter information switch (Refer to DISASSEMBLY AND ASSEMBLY  ).

   Q: Is the check result normal? 

   YES  : Go to Step 4.

   NO  : Replace the meter information switch.

4. STEP 4. Measure at meter information switch connector C-34 in order to the ground circuit to the meter information switch. 
   1. Disconnect meter information switch connector C-34, and measure at the wiring harness side.
   2. Measure the resistance value between terminal 4 and ground.
      • The measured value should be 2 ohm or less.

   Q: Does the measured resistance value correspond with this range? 

   YES  : Go to Step  6.

   NO  : Go to Step 5.

5. STEP 5. Check the wiring harness between meter information switch connector C-34 (terminal 4) and grounding connector C-01 (terminal 11). 
   • Check the ground wire for open circuit.
   NOTE: Also check joint connector C-108. If joint connector C-108 are damaged, repair or replace the connector as described in GROUP 00E, HARNESS CONNECTOR INSPECTION .

   Q: Is the wiring harness between fuel meter information switch connector C-34 (terminal 4) and grounding connector C-01 (terminal 11) in good condition? 

   YES  : Go to Step 6.

   NO  : Repair the wiring harness.

6. STEP 6. Check combination meter connector C-203 for loose, corroded or damaged terminals, or terminals pushed back in the connector. 

   Q: Is combination meter connector C-203 in good condition? 

   YES  : Go to Step 7.

   NO  : Repair the connector.

7. STEP 7. Check the wiring harness between meter information switch connector C-34 (terminal 1) and combination meter connector C-203 (terminal 3). 
   • Check the output line for open circuit.

   Q: Are the wiring harness between meter information switch connector C-34 (terminal 1) and combination meter connector C-203 (terminal 3) in good condition? 

   YES  : Go to Step 8.

   NO  : Repair the wiring harness.

8. STEP 8. Retest the system. 

   Check that the multi information display screen switches normally when the meter information switch is operated.

   Q: Is the check result normal? 

   YES  : The trouble can be an intermittent malfunction (Refer to HOW TO COPE WITH INTERMITTENT MALFUNCTION ).

   NO  : Replace the combination meter.
