Wiper Control Module Inputs
CIRCUIT OPERATIONThe following covers the inputs to the wiper control module from the wiper switch and the wiper motors.
Battery Feed
Circuit M1 supplies a constant battery feed to the wiper control module. The M1 circuit is protected by a 20 Amp fuse located in cavity 15 of the fuse block and HOT at all times.
Ignition Feed
Circuit V6 supplies a ignition feed input to the wiper control module. The V6 circuit is protected by a 20 Amp fuse located in cavity 18 of the fuse block. This fuse is HOT in the RUN and ACCESSORY position.
Intermittent Wiper Signal
The V7 circuit provides a variable voltage signal to the wiper control module when the operator has turned the intermittent wiper switch ON. Ground for the switch is supplied on the V17 circuit to the control module from the switch.
Low Speed Signal
Circuit V3 provides a ground path for the switch when it is in the LOW speed position to the control module.
High Speed Signal
Circuit V4 provides a ground path for the switch when it is in the HIGH speed position to the control module.
Washer Switch Signal
The V10 circuit provides a ground path for the switch when it is in the WASH position to the control module.
Motor Switch Signals (Drivers Side)
Circuits V45 and V48 provide the wiper control module with information on the position of the driver's side wiper arm. Circuit V45 is used for switch 1, and V48 is used for switch 2.
Motor Switch Signals (Passenger's Side)
Circuits V46 and V47 provide the wiper control module with information on the position of the passenger's side wiper arm. Circuit V46 is used for switch 1, and V47 is used for switch 2.
Speed Signals
Circuits V56 and V57 provide a pulse signal to the wiper control module. The pulse signal has a voltage range from 0 to 5 Volts and represents a wiper motor RPM to the wiper control module.
Circuit V56 is the input from the driver's wiper motor, and circuit V57 is the input from the passenger's wiper motor.
