How To Proceed With Troubleshooting

Troubleshoot in accordance with the following procedures.

1. VEHICLE BROUGHT TO WORKSHOP 
2. CUSTOMER PROBLEM ANALYSIS CHECK AND SYMPTOM CHECK (See  PROBLEM SYMPTOMS TABLE  ) 
3. INSPECT COMMUNICATION FUNCTION OF LARGE-SCALE MULTIPLEX COMMUNICATION SYSTEM (BEAN) 
   1. Check that there is no abnormality in the communication system by inspecting the communication function of the multiplex communication system.
      1. (ECU communication stop, communication line abnormal) With code outputs, proceed to A.
      2. (ECU communication stop, communication line abnormal) Without code outputs, proceed to B.
   1. A : Go to Next Step 
   2. B : Go To Section Of Each System 
4. DIAGNOSTIC TROUBLE CODE CHECK (See  DIAGNOSTIC TROUBLE CODE CHART  ) 
   1. Check for DTCs and make a note of the code that is output.
   2. Delete the DTC.
   3. Check if the DTC will be output once again, when the problem symptom is simulated based on the noted code.
      1. When no code is output (symptom check and simulation is possible), proceed to A.
      2. When a code is output, proceed to B.
   1. A : Go To Next Step 
   2. B : Go to step   7 
5. PROBLEM SYMPTOMS TABLE   (See ) 
   1. Without applicable symptoms, proceed to A.
   2. With applicable symptoms, proceed to B.
   1. A : Go To Next Step 
   2. B : Go to step   7 
6. PERFORM TROUBLESHOOTING IN FOLLOWING METHOD, DEPENDING ON MALFUNCTION SYMPTOM 
   1. See PRE-CHECK 
   2. See TERMINALS OF ECU 
7. ADJUST, REPAIR OR REPLACE 
   1. END
