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, 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 msec, but less than 1/2 second, 1 wipe cycle in low speed mode will be provided.

Wipe After Wash Mode
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 provide intermittent operation. The low and high speed are run directly from the multifunction switch. The BCM controls the intermittent relay to change the wiper delay as the multifunction switch input changes. The BCM uses vehicle speed input to double the usual delay times below 10 MPH.

The diagnostic trouble codes associated with the wiper relay are set based on the resistance and current flow in the relay control circuit.
