How To Proceed With Troubleshooting

HINT:

• Use these procedures to troubleshoot the electronic shift lever system.
• ^* : Use the intelligent tester.

1. VEHICLE BROUGHT TO WORKSHOP 

   NEXT 

2. INSPECT BATTERY VOLTAGE 

   Standard voltage: 11 to 14 V 

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

   NEXT 

3. CHECK COMMUNICATION FUNCTION OF MULTIPLEX COMMUNICATION SYSTEM (BEAN) ^* 
   1. Use the intelligent tester to check if the Multiplex Communication System (MPX) is functioning normally.

      Result 

      RESULT REFERENCE
      
      

      Result	Proceed to
      MPX DTC is not output	A
      MPX DTC is output	B

   B : Go to MULTIPLEX COMMUNICATION SYSTEM 

   A : GO TO NEXT STEP 

4. CHECK COMMUNICATION FUNCTION OF CAN COMMUNICATION SYSTEM ^* 
   1. Use the intelligent tester to check if the CAN communication system is functioning normally.

      Result 

      RESULT REFERENCE
      
      

      Result	Proceed to
      CAN DTC is not output	A
      CAN DTC is output	B

   B : Go to CAN COMMUNICATION SYSTEM 

   A : GO TO NEXT STEP 

5. CHECK FOR DTC ^* 
   1. Check for DTCs and note any codes that are output.
   2. Delete the DTC.
   3. Recheck for DTCs. Based on the DTCs output above, try to force output of the electronic shift lever system DTC by simulating the operation indicated by the DTC.

      Result 

      RESULT REFERENCE
      
      

      Result	Proceed to
      DTC is not output	A
      DTC is output	B

   B : Go to step   8 

   A : GO TO NEXT STEP 

6. PROBLEM SYMPTOMS TABLE 

   Refer to the PROBLEM SYMPTOMS TABLE  .

   Result

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

   B : Go to step   8 

   A : GO TO NEXT STEP 

7. OVERALL ANALYSIS AND TROUBLESHOOTING ^* 
   1. DATA LIST / ACTIVE TEST 
   2. TERMINALS OF ECU
