System summarization
• Contacts of IG power supply relay will be closed when the ignition switch is turned on, and the current will flow to
main fuse F/L0 from battery, to fuse F/L4, to fuse F20, to pin No. 18 of combined switch; and make the wiper and
washer work through combined switch.
Low speed of wiper
• Turn on the ignition switch when combined switch is at low speed, contacts of IG power supply relay will be
closed, and current will flow to main fuse F/L0 from battery, to fuse F/L4, to fuse F20, to pin No. 18 of combined
switch; from pin No. 7 of combined switch to pin No. 2 of wiper motor, and ground through pin No. 3 of wiper
motor.
High speed of wiper
• Turn on the ignition switch when combined switch is at high speed, contacts of IG power supply relay will be
closed, and current will flow to main fuse F/L0 from battery, to fuse F/L4, to fuse F20, to pin No. 18 of combined
switch; from pin No. 13 of combined switch to pin No. 2 of wiper motor, and ground through pin No. 3 of wiper
motor.
Water injection shift of the wiper
• Turn on the ignition switch when combined switch is at water injection shift, contacts of IG power supply relay
will be closed, and current will flow to main fuse F/L0 from battery, to fuse F/L4, to fuse F20, to pin No. 1 of
washer motor; from pin No. 2 of washer motor to pin No. 8 of combined switch, and ground through pin No. 12 of
combined switch.
