B2311
WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: B2311: Power Window Motor Malfunction
B2311 - Power Window Motor Malfunction
DESCRIPTION
The power window regulator motor is operated by the multiplex network master switch assembly, power window regulator switch assembly or rear power window regulator switch assembly. The power window regulator motor assembly has motor, regulator and ECU functions.
This DTC is output when the power window regulator motor assembly has a malfunction, or the ECU built into the power window regulator motor assembly determines that the fully closed window position has deviated approximately 20 mm (0.787 in.) or more from the normal position.
D-Door Motor (Power Window Regulator Motor Assembly (for Driver Side))
P-Door Motor (Power Window Regulator Motor Assembly (for Front Passenger Side))
RL-Door Motor (Power Window Regulator Motor Assembly (for Rear LH Side))
RR-Door Motor (Power Window Regulator Motor Assembly (for Rear RH Side))
INSPECTION PROCEDURE
NOTICE:
* DTC B2311 can be stored in each power window regulator motor assembly (power window ECU).
* If a power window regulator motor assembly has been replaced with a new one, initialize the power window control system Initialization.
* If a power window regulator motor assembly and door window regulator sub-assembly have been removed and installed, or if a power window regulator motor assembly was reused when a door glass or door glass run was replaced, initialize the power window control system Initialization.
PROCEDURE
1. PERFORM ACTIVE TEST USING TECHSTREAM (APPLICABLE LOCATION)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / (desired system) / Active Test.
HINT
Perform the Active Test for the power window regulator motor assembly that has DTC B2311 stored in its ECU.
(e) Perform the Active Test according to the display on the Techstream.
CAUTION:
Be careful to avoid injuries as this test causes vehicle parts to move. During the Active Test, the jam protection function will not operate.
D-Door Motor (Power Window Regulator Motor Assembly (for Driver Side))
P-Door Motor (Power Window Regulator Motor Assembly (for Front Passenger Side))
RL-Door Motor (Power Window Regulator Motor Assembly (for Rear LH Side))
RR-Door Motor (Power Window Regulator Motor Assembly (for Rear RH Side))
OK:
Each power window motor operates.
Result:
C -- REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Rear LH Side or Rear RH Side) Removal
B -- REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Driver Side or Front Passenger Side) Removal
A -- Continue to next step.
2. PERFORM INITIALIZATION (APPLICABLE LOCATION)
(a) Initialize the power window regulator motor assembly Initialization.
HINT
Initialize the power window regulator motor assembly that has DTC B2311 stored in its ECU.
NEXT -- Continue to next step.
3. CHECK POWER WINDOW CONTROL SYSTEM (APPLICABLE LOCATION)
(a) Check that the power window operates normally by opening and closing the window Operation Check.
HINT
Check the power window operation of the window where DTC B2311 has been stored.
OK:
Each power window operates normally.
Result:
C -- REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Rear LH Side or Rear RH Side) Removal
B -- REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Driver Side or Front Passenger Side) Removal
A -- Continue to next step.
4. CHECK WHETHER PARTS HAVE BEEN INSTALLED CORRECTLY
(a) Check that the power window components are installed correctly.
OK:
Power window components are installed correctly.
HINT
When the power window components are installed correctly, the problem has occurred because the auxiliary battery is disconnected while the power switch is on (IG), the power window components are installed improperly or the motor is overheated.
NG -- INSTALL PARTS CORRECTLY
OK -- END
