How To Proceed With Troubleshooting

HINT:

• Use these procedures to troubleshoot the meter / gauge system.
• *: Use Techstream.

1. VEHICLE BROUGHT TO WORKSHOP 
2. INSPECT BATTERY VOLTAGE 

   Standard voltage: 

   11 to 14 V 

   If the voltage is below 11V, recharge or replace the battery before proceeding.

3. CHECK FOR DTC* 
   1. Check for DTCs and note any codes that are output (see DTC CHECK/CLEAR  ).
   2. Delete the DTCs (see DTC CHECK/CLEAR  ).
   3. Recheck for DTCs. Based on the DTCs output above, try to force output of the same CAN communication system DTC or meter / gauge system DTC by simulating the symptoms indicated by the DTC.

      Result: 

      DTC RESULT REFERENCE
      
      

      Result	Proceed to
      DTC is not output	A
      CAN communication system DTC is output	B
      Meter / gauge system DTC is output	C

   B: Go to CAN COMMUNICATION SYSTEM  (See CAN COMMUNICATION SYSTEM )

   C:  Go to DIAGNOSTIC TROUBLE CODE CHART 

   A: Go to next step 

4. PROBLEM SYMPTOMS TABLE 
   1. Refer to the PROBLEM SYMPTOMS TABLE  .

      Result: 

      PROBLEM SYMPTOMS RESULT REFERENCE
      
      

      Result	Proceed to
      Fault is not listed in problem symptoms table	A
      Fault is listed in problem symptoms table	B

   B:  Go to step  6

   A: Go to next step 

5. OVERALL ANALYSIS AND TROUBLESHOOTING* 
   1. Terminals of ECU (see TERMINALS OF ECU  )
   2. DATA LIST / ACTIVE TEST (see DATA LIST / ACTIVE TEST  )
   3. Operation check (see OPERATION CHECK  )
6. REPAIR OR REPLACE 
7. CONFIRMATION TEST
