Front Wiper Auto Operation
WARNING: This page is about a different car, the 2018 Nissan Titan XD and 2018 Nissan Titan. However, it is still accessible from the selected car via links, so may be relevant.
Rain Detection
Rain level and sensor conditions are detected by rain sensor.
- BCM transmits the vehicle conditions (vehicle speed, front wiper condition, rain sensor sensitivity setting, etc.) to the rain sensor via the rain sensor serial link.
- Rain sensor judges a wiping speed for front wiper by rain condition and the vehicle conditions. It transmits the wiping speed request signal to the BCM via the rain sensor serial link.
Auto Wiping Operation
- BCM receives the wiping speed request signal from the rain sensor via the rain sensor serial link.
- BCM controls front wiper operation according to the wiping speed request signals. It transmits the front wiper request signals (LO or HI) to the IPDM E/R via CAN communication line.
Front wiper AUTO operating condition
- Ignition switch ON
- Front wiper switch AUTO
NOTE:
- When the front wiper switch is turned to AUTO position, the front wiper operates once regardless of rainy conditions.
- Factory setting of the front wiper AUTO operation is the operation linked with rain sensor. Front wiper AUTO operation can be set to operation linked or not linked with rain sensor using CONSULT. Refer to CONSULT Function (BCM - WIPER) .
Rain Sensor Sensitivity Setting
BCM determines rain sensor sensitivity according to wiper volume dial position.
|
Wiper volume dial position |
Sensitivity |
|
1 |
High sensitivity |
|
2 |
Medium-high sensitivity |
|
3 |
Low-medium sensitivity |
|
4 |
Low sensitivity |
NOTE:
When the wiper volume dial position is turned up by 1 level under front wiper AUTO operating condition, the front wiper operates once.
Splash mode operation
The front wiper is operated at HI regardless of the wiper volume adjustment position when water drops are instantaneously sprayed over the windshield glass due to water splash from oncoming vehicles or other causes. After that, AUTO operation is performed depending on the amount of water drops.
SPLASH MODE OPERATION CONDITIONS
- Front wiper switch AUTO
- Ignition switch ON
NOTE:
Splash mode is not operated and auto wiping operation is performed while the vehicle is stopped.
