DESCRIPTION
The power window regulator motor is driven by operating the power window regulator switch. The power window regulator motor consists of the motor, regulator and ECU.
This DTC is stored when the power window regulator motor has a malfunction, or the ECU built into the power window regulator motor determines that the fully closed window position has deviated approximately 20 mm (0.787 in.) or more from the normal position.
HINT
This DTC may be stored for all the windows.
Note. When the power window regulator motor is reinstalled or replaced, the power window control system must be initialized. After a door glass or a door glass run has been replaced, the jam protection function may operate unexpectedly when the auto up function is used. In such cases, the auto up function can be resumed by repeating the following operation at least 5 times: Close the power window by fully pulling up the power window switch and holding it in the auto up position. Open the power window by fully pushing down the switch.

The power window regulator motor assembly is driven by operating the power window switch. The power window regulator motor assembly has motor, regulator and ECU functions.
When the ECU determines that the power window regulator motor has not been initialized, DTC B2313 is stored.
HINT
This DTC may be stored for all the windows.
Note. When the power window regulator motor is reinstalled or replaced, the power window control system must be initialized. After a door glass or a door glass run has been replaced, the jam protection function may operate unexpectedly when the auto up function is used. In such cases, the auto up function can be resumed by repeating the following operation at least 5 times: Close the power window by fully pulling up the power window switch and holding it in the auto up position.

When the engine switch is on (IG) and window lock switch is off, the multiplex network master switch sends remote up/down signals to each power window regulator motor via the LIN communication line.

- If the manual up/down function does not operate, there may be a malfunction in the multiplex network master switch, power window regulator motor, harness or connector.
Scheme 125
- If the manual up/down function does not operate, there may be a malfunction in the power window regulator switch, front power window regulator motor RH, harness or connector.
Scheme 126

- The Hall-IC in the power window regulator motor has a malfunction.
- There is an open or short in the wiring between the power window regulator switch and the front power window regulator motor.
Scheme 129
- If the auto up/down function does not operate, the cause may be one or more of the following
- The ECU in the power window regulator motor determines that the power window regulator motor has not been initialized.
- The power window regulator switch has a malfunction.
- The Hall-IC in the power window regulator motor has a malfunction.
- There is an open or short in the wiring between the rear power window regulator switch and the rear power window regulator motor.
Scheme 130
- If the auto up/down function does not operate, the cause may be one or more of the following
- The ECU in the power window regulator motor determines that the power window regulator motor has not been initialized.
- The power window regulator switch has a malfunction.
- The Hall-IC in the power window regulator motor has a malfunction.
- There is an open or short in the wiring between the rear power window regulator switch and the rear power window regulator motor.
Scheme 131
- When a transmitter switch is pushed, the following occurs: 1) the door control receiver receives the transmitter signal; 2) the door control receiver sends a signal to the main body ECU; 3) the main body ECU sends the operation permission signal to the power window regulator motors; and 4) the power window motors are activated.
- When the driver door key cylinder (key linked switch) is turned, the following occurs: 1) the door lock motor receives the signal; 2) the door lock motor sends the signal to the main body ECU; 3) the main body ECU sends the signal to the power window regulator motors; and 4) the power window motors are activated.
- When the front doors are closed, each power window regulator motor can control its power window operation for approximately 45 seconds after the engine switch is turned from on (IG) to off by receiving operation permission signals from the main body ECU.
- However, when approximately 45 seconds have elapsed, or the driver side door or front passenger side door is opened within approximately 45 seconds of the engine switch being turned off, the power window regulator motor stops operating.
- During the auto function operation, when 45 seconds have passed and key-off operation is prohibited, the window operation stops immediately.
- The front passenger side power window and the rear power windows cannot be operated when the window lock switch is on.
- This symptom may occur to all door windows.
- If the door glass or the power window regulator motor does not operate smoothly, the jam protection function may be triggered automatically, resulting in the auto up function being unable to fully close the window.
- This symptom may occur to all door windows. The jam protection function operates within a specified range during the manual up or auto up operation.
When an entry lock switch is pressed and held for approximately 3 seconds: 1) the main body ECU transmits a signal to all the power window regulator motors, and 2) all the power window motors are activated to close the windows.
