DESCRIPTION
The power window regulator motor assembly LH (for driver door) is operated by the power window regulator master switch assembly. The power window regulator motor assembly LH (for driver door) has motor, regulator and ECU functions.
This DTC is stored when the power window regulator motor assembly LH (for driver door) has a malfunction, or the ECU built into the regulator motor assembly determines that the fully closed window position has deviated approximately 20 mm (0.787 in.) or more from the normal position.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| B2311 | Either condition is met: Power window regulator motor assembly is malfunctioning When ECU in power window regulator motor assembly determines that fully closed window position has deviated approx. 20 mm (0.787 in.) or more from normal position | Power window regulator motor assembly LH (for driver door) Incorrect installation of power window components Overheated power window regulator motor assembly LH (for driver door) |
The power window regulator motor assembly LH (for driver door) is operated by the power window regulator master switch assembly. The power window regulator motor assembly LH (for driver door) has motor, regulator and ECU functions.
This DTC is stored when the ECU built into the regulator motor determines that the power window regulator master switch assembly is stuck.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| B2312 | Power window regulator master switch assembly (for driver door) stuck Power window regulator master switch assembly held in same position for more than 20 seconds | Power window regulator master switch assembly Power window regulator motor assembly LH (for driver door) Wire harness or connector |
Scheme 89
The power window regulator motor assembly LH (for driver door) is operated by the power window regulator master switch assembly. The power window regulator motor assembly LH (for driver door) has motor, regulator and ECU functions.
When the ECU determines that the power window regulator motor assembly LH (for driver door) has not been initialized, DTC B2313 is stored.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| B2313 | Power window regulator motor assembly not initialized Power window regulator motor assembly is malfunctioning Auxiliary battery disconnected when ignition switch ON (IG) | Power window regulator motor assembly LH (for driver door) not initialized Power window regulator motor assembly LH (for driver door) |
With the ignition switch ON (IG), the power window regulator master switch assembly transmits remote operation signals to each power window regulator switch assembly. Then, the power window regulator switch assembly drives each power window regulator motor assembly.
Scheme 90
When the ignition switch is ON (IG), the power window regulator motor assembly LH (for driver door) is operated by the power window regulator master switch assembly. The power window regulator motor assembly LH (for driver door) has motor, regulator and ECU functions.
When the ignition switch is ON (IG), the power window regulator motor assembly RH (for front passenger door) is operated by the power window regulator switch assembly (for front passenger door).
Scheme 91
When the ignition switch is ON (IG), the power window regulator motor assembly LH (for rear LH door) is operated by the power window regulator switch assembly (for rear LH door).
Scheme 92
When the ignition switch is ON (IG), the power window regulator motor assembly RH (for rear RH door) is operated by the power window regulator switch assembly (for rear RH door).
Scheme 93
If the manual up and down functions operate normally but the auto up and down functions do not, then fail-safe mode may be functioning.
If power window initialization. Refer to INITIALIZATION [12/2013 - ] has not been performed, the auto up and down functions will not operate.
- When the front doors are closed, each power window regulator motor assembly can control its power window operation for approximately 43 seconds after the ignition switch is turned from ON (IG) to off by receiving operation permission signals from the main body ECU (multiplex network body ECU).
- However, when approximately 43 seconds have elapsed, or the driver door or front passenger door is opened within approximately 43 seconds of the ignition switch being turned off, the power window regulator motor assembly stops operating.
- During an auto operation, when 43 seconds have passed and key-off operation is prohibited, the window operation stops immediately.
If the driver door glass or the power window regulator motor assembly LH (for driver door) 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.
The jam protection function operates within a specified range during the manual up or auto up operation.
The power windows operate by using the power window regulator master switch assembly or power window regulator switch assemblies.
The power window regulator master switch assembly and each power window regulator switch assembly connect the same power supply and ground lines.
