PULSE FAILURE OR DISPLACEMENT OF NON-DETECTION RANGE TO THE OPENING DIRECTION
If the pulse sensor built into the front power window regulator motor assembly LH (for LHD) or front power window regulator motor assembly RH (for RHD) malfunctions, the power window control system enters fail-safe mode.
| Power Window Operation | Condition | ||
|---|---|---|---|
| Ignition switch ON | Ignition switch off (Key-off operation permitted) |
Ignition switch off (Key-off operation prohibited) |
|
| Manual up (Driver door window) | X | X | - |
| Manual down (Driver door window) | ○ | X | - |
| Auto up (Driver door window) (Hold switch in auto up position) |
○* | X | - |
| Auto up (Driver door window) | X | X | - |
| Auto down (Driver door window) | X | X | - |
Tech Tips
○: Operates
X: Operation prohibited
*: Operates in manual mode without jam protection
Fail-safe deactivation condition
When the pulse sensor is normal, to deactivate fail-safe mode, pull up the power window regulator master switch assembly to the auto up position and hold it for at least 1 second to fully close the window from the fully open position. As a result, the auto up/down function will return.
INITIAL FAILURE
During initialization of the power window regulator motor ECU, when the window position or initialization complete status cannot be properly read from the EEPROM, the power window control system prohibits operation as follows.
| Power Window Operation | Condition | ||
|---|---|---|---|
| Ignition switch ON | Ignition switch off (Key-off operation permitted) |
Ignition switch off (Key-off operation prohibited) |

*: Operates in manual mode without jam protection
Fail-safe deactivation condition
Initialize the front power window regulator motor assembly LH (for LHD) or front power window regulator motor assembly RH (for RHD).
LIN COMMUNICATION FAILURE
If the LIN communication line is malfunctioning (communication stop), the power window control system prohibits operation as follows.
| Power Window Operation | Condition |
|---|---|
| Ignition switch ON | |
| Manual up | ○* |
| Manual down | ○ |
| Auto up (Hold switch in auto up position) | ○* |
| Auto up | ○* |
| Auto down | ○ |
Tech Tips
○: Operates
*: Jam protection can operate.
Fail-safe deactivation condition
Check LIN communication system.
PULSE FAILURE AND LIN COMMUNICATION FAILURE
If the LIN communication line is malfunctioning (communication stop) and the pulse sensor for the jam protection function is malfunctioning, the power window control system prohibits operation as follows.
| Power Window Operation | Condition |
|---|---|
| Always | |
| Manual up | X |
| Manual down | X |
| Auto up (Hold switch in auto up position) | X |
| Auto up | X |
| Auto down | X |
Tech Tips
X: Operation prohibited
When the jam protection function does not operate due to a LIN communication failure, the manual up and auto up functions will not operate.
DISPLACEMENT OF NON-DETECTION RANGE TO THE OPENING DIRECTION AND LIN COMMUNICATION FAILURE / INITIAL FAILURE AND LIN COMMUNICATION FAILURE
If the LIN communication line is malfunctioning (communication stop) and the window position or the learned value is abnormal, the power window control system prohibits operation as follows.
| Power Window Operation | Condition |
|---|---|
| Always | |
| Manual up | ○* |
| Manual down | ○ |
| Auto up (Hold switch in auto up position) | ○* |
| Auto up | X |
| Auto down | X |
Tech Tips
○: Operates
X: Operation prohibited
*: Jam protection can operate and window reverses upon reaching the fully closed position.
