Rain Sensing Wiper (For CANADA Only)
In IGN2 ON state, if auto switch input (LIN communication) is ON then both wiper low relay and wiper high relay outputs are controlled by the rain sensor input signal 1.
When the wiper switch is moved to auto position and the Ignition switch is in IGN2 position, the Rain sensor is considered to be in "automatic" mode
- If the wiper switch has been left in automatic mode with the vehicle ignition OFF, and then the vehicle ignition switch is turned on, a single wipe will be performed.
- A single wipe will be performed whenever rain has been detected (Rain Detected signal from Rain sensor) and the wiper switch is moved to the AUTO position. But a single wipe will not be performed when the wiper switch is moved to the AUTO position and OFF signal is being received from Rain sensor. But if the wiper switch is moved to AUTO position for the first time since vehicle ignition switch is turned on then a single wipe will be performed regardless of rain detected or OFF signal.
- Sensitivity Adjustment Function (Instant Wipe Function)
The drive may adjust the rain sensor performance by adjusting the sensitivity input. When in AUTOMATIC mode, the BCM will perform a single wipe each time the sensitivity is adjusted upward to a more sensitive setting (downward more then one step). This single wipe will only be performed if Rain Detected signal is being received from the Rain sensor. If the sensitivity adjustment is adjusted upward more than one sensitivity, the BCM will only perform a single wipe unless the time between increases is more than 2 seconds.
