Front wiper on relay

The front wiper switch is a direct input to the BCM. The BCM sends a PCI Bus message to the IPM informing it to turn on the front wiper on relay. This relay is electronically controlled and continuously monitored for malfunctions. The front wiper on relay is turned on internally by the IPM as soon as the IPM receives the message from the BCM.
