System Features

Speed Sensitive Intermittent Wipe Mode 

There are 6 individual delay times with a minimum delay of 1/2 second to a maximum of 18 seconds. When the vehicle speed is under 10 MPH (6 KMH), the delay time is doubled providing a range of 1 second to 36 seconds.

Pulse Wipe 

When the wiper is in the off position and the driver presses the wash button for more than 62 milliseconds, but less than 1/2 second, 2 wipe cycle in low speed mode will be provided.

Park after Ignition Off 

Because the wiper relays are powered from the battery the BCM can run the wipers to park after the ignition is turned off.

Wipe after Wash 

When the driver presses the wash button for over 1/2 second and then releases it, the wiper will continue to run for 2 additional wipe cycles.

The wiper system utilizes the BCM to control the on/off and hi/low relays for low and hi speed wiper functions, intermittent wiper delay as the switch position changes, pulse wipe, wipe after wash mode, and wiper motor park functions. The BCM uses the vehicle speed input to double the usual delay time below 10 MPH (6 KMH).
