How To Proceed With Troubleshooting

HINT:

• Use these procedures to troubleshoot the rear sunshade system.
• *: Use the intelligent tester or Techstream.

1. VEHICLE BROUGHT TO WORKSHOP 
2. INSPECT BATTERY VOLTAGE 

   Standard voltage: 11 to 14 V 

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

3. CHECK FOR DTC (ELECTRIC POWER CONTROL SYSTEM)* 
   1. Using the intelligent tester or Techstream, check if the electric power control system is functioning normally.

      Result 

      FOR DTC (ELECTRIC POWER CONTROL SYSTEM)
      
      

      Result	Proceed to
      DTC B22B3 is not output	A
      DTC B22B3 is output	B

   B: Go to ELECTRIC POWER CONTROL SYSTEM  (see DIAGNOSTIC TROUBLE CODE CHART )

   A: GO TO NEXT STEP 

4. INSPECT COMMUNICATION FUNCTION OF CAN COMMUNICATION SYSTEM* 
   1. Use the intelligent tester or Techstream to check if the CAN Communication System is functioning normally.

      Result 

      COMMUNICATION FUNCTION OF CAN COMMUNICATION SYSTEM
      
      

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

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

   A: GO TO NEXT STEP 

5. INSPECT COMMUNICATION FUNCTION OF LIN COMMUNICATION SYSTEM* 
   1. Use the intelligent tester or Techstream to check if the LIN Communication System is functioning normally.

      Result 

      COMMUNICATION FUNCTION OF LIN COMMUNICATION SYSTEM
      
      

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

   B: Go to LIN COMMUNICATION SYSTEM  (See DIAGNOSTIC TROUBLE CODE CHART )

   A: GO TO NEXT STEP 

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

      Result 

      RESULT CHART
      
      

      Result	Proceed to
      Fault not listed in problem symptoms table	A
      Fault 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 (see DATA LIST / ACTIVE TEST  )
   2. Terminals of ECU (see TERMINALS OF ECU  )
   3. Operation Check (see OPERATION CHECK  )
8. REPAIR OR REPLACE 
9. CONFIRMATION TEST
