PULSE FAILURE OR DISPLACEMENT OF NON-DETECTION RANGE TO THE OPENING DIRECTION
If the pulse sensor built into the power window regulator motor malfunctions, the power window control system enters fail-safe mode.
| Power Window Operation | Condition | ||
|---|---|---|---|
| Power switch on (IG) | Power switch off (Key-off operation permitted) |
Power 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 at 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 switch 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 | ||
|---|---|---|---|
| Power switch on (IG) | Power switch off (Key-off operation permitted) |
Power switch off (Key-off operation prohibited) |

*: Operates in manual mode without jam protection
Fail-safe deactivation condition
Initialize the front door window regulator assembly (for driver door).
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 |
|---|---|
| Power switch on (IG) | |
| Manual up | ○* |
| Manual down | ○ |
| Auto up (hold switch at auto up position) | ○* |
| Auto up | ○* |
| Auto down | ○ |
Tech Tips
○: Operates
X: Operation prohibited
*: 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 at auto up position) | X |
| Auto up | X |
| Auto down | X |
Tech Tips
○: Operates
X: Operation prohibited
When the jam protection function does not operate due to the 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 at 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.
