How To Proceed With Troubleshooting

HINT:

• Use these procedures to troubleshoot the power door lock control 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 ELECTRIC POWER CONTROL 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 

      COMMUNICATION FUNCTION OF CAN COMMUNICATION SYSTEM
      
      

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

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

   A: GO TO NEXT STEP 

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

      Result 

      OMMUNICATION FUNCTION OF LIN COMMUNICATION SYSTEM
      
      

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

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

   A: GO TO NEXT STEP 

6. CHECK FOR DTC* 
   1. Check for DTCs (see DTC CHECK / CLEAR  ).
   2. Clear the DTCs (see DTC CHECK / CLEAR  ).
   3. Recheck for DTCs (see DTC CHECK / CLEAR  ).

      Result 

      RESULT REFERENCE
      
      

      Result	Proceed to
      DTC does not reoccur	A
      DTC reoccurs	B

   B:  Go to DIAGNOSTIC TROUBLE CODE CHART 

   A: GO TO NEXT STEP 

7. PROBLEM SYMPTOMS TABLE 

   Result 

   PROBLEM SYMPTOMS CHART
   
   

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

   B: Go to step   9 

   A: GO TO NEXT STEP 

8. OVERALL ANALYSIS AND TROUBLESHOOTING* 
   1. Operation Check (see OPERATION CHECK  )
   2. Data List / Active Test (see DATA LIST / ACTIVE TEST  )
   3. Terminals of ECU (see TERMINALS OF ECU  )
9. ADJUST, REPAIR OR REPLACE 
10. CONFIRMATION TEST
