Intermittent (D)
When intermittent wiping is selected on the wiper stalk-switch the CIM (703) transmits a "Windscreen wiper, stalk-switch, position INTERMITTENT" message on the bus. The message is processed by the UEC (342) which activates relay 83 and the wiper motor (62F) is connected to the voltage supply. The UEC (342) supplies B+ on pin 30 which is connected to pin 4 on the wiper motor (62F). Pin 3 on the wiper motor is connected to ground. If the ignition is switched off when the wiper blades are not in the parking position the UEC (342) continues to run the motor until the parking position is reached. The intermittent wiping interval can be set to between 2 and 15 seconds.
