DTC B2313: Driver Side Glass Position Initialization Incomplete; DTC B2316: Passenger Side Glass Position Initialization Incomplete [06/2016 - ]: Procedure

1. Turn the ignition switch to ON.
2. Initialize the power window regulator master switch assembly or power window regulator switch assembly (Refer to INITIALIZATION [06/2016 - ] ).

Result: 

NEXT 

See step  2

1. Clear the DTCs (Refer to DTC CHECK / CLEAR [06/2016 - ] ).
2. Check for DTCs (Refer to DTC CHECK / CLEAR [06/2016 - ] ).

   HINT: 

   Check for DTCs for the power window regulator master switch assembly or power window regulator switch assembly that has DTC B2313 or B2316 stored in its ECU.

   OK

   DTC B2313 or B2316 is not output.

Result: 

A 

See step  4

1. Disconnect the E8 power window regulator master switch assembly connector.
2. Disconnect the E5 power window regulator motor assembly connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance (Check for Open)

   Tester Connection	Condition	Specified Condition
   E8-8 (SN1) - E5-6 (SN1)	Always	Below 1 Ω
   E8-1 (SN2) - E5-2 (SN2)	Always	Below 1 Ω

   Standard Resistance (Check for Short):

   Tester Connection	Condition	Specified Condition
   E8-8 (SN1) or E5-6 (SN1) - Body ground	Always	10 kΩ or higher
   E8-1 (SN2) or E5-2 (SN2) - Body ground	Always	10 kΩ or higher

Result: 

OK
