How To Proceed With Troubleshooting

HINT:

• Use these procedures to troubleshoot the power window 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 11V, 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 

      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. 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 in the first step, try to force output of the same DTC by simulating the symptoms indicated by the DTC.

      Result	Proceed to
      No DTCs output	A
      B2311 is output	B
      B2312 is output	B
      B2313 is output	B
      CAN communication system DTC output reoccur	C
      LIN communication system DTC output reoccur	D

   B: GO TO  DIAGNOSTIC TROUBLE CODE CHART  

   C: GO TO CAN COMMUNICATION SYSTEM  (See CAN COMMUNICATION SYSTEM )

   D: GO TO LIN COMMUNICATION SYSTEM  (See HOW TO PROCEED WITH TROUBLESHOOTING )

   A: GO TO NEXT STEP 

5. PROBLEM SYMPTOMS TABLE

   Fault listed in problem symptoms table	B

   B: GO TO STEP   7 

   A: GO TO NEXT STEP 

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

   Result:

   Result	Proceed to
   Door window regulator and power window regulator motor assembly is not replaced or removed/installed.	A
   Door window regulator and power window regulator motor assembly is replaced or removed/installed.	B

   A: GO TO STEP   9 

   B: GO TO NEXT STEP 

8. RESET POWER WINDOW MOTOR 
   1. If the power window master switch AUTO light is blinking, reset the power window motor (see INITIALIZATION  ).
9. CONFIRMATION TEST
