Inspection Procedure

1. Check for LIN communication system DTCs related to the power window control system (See DTC CHECK/CLEAR ).

   OK: LIN communication system DTCs are not output. 

NG: GO TO LIN COMMUNICATION SYSTEM  (See DIAGNOSTIC TROUBLE CODE CHART )

OK: Go to Next Step 

1. Check if DTC B2312 is output (See DTC B2312 POWER WINDOW SWITCH MALFUNCTION  ).

   OK: DTC B2312 is not output. 

NG: GO TO DTC B2312  (See DTC B2312  )

OK: Go to Next Step 

1. Use the Data List to check if the power window regulator motor is functioning properly (See DATA LIST/ACTIVE TEST  ).
