Auto Stop Operation

With wiper switch turned OFF, wiper motor will continue to operate until wiper arms reach windshield base.

When wiper arms are not located at base of windshield with wiper switch OFF, ground is provided

• from IPDM E/R terminal 21
• to front wiper motor terminal 1, in order to continue wiper motor operation at low speed.

When wiper arms reach base of windshield, front wiper motor terminals 5 and 2 are connected, and Ground is supplied

• to IPDM E/R terminal 32
• through front wiper motor terminals 5 and 2
• through grounds E21, E50 and E51.

Then the IPDM E/R sends auto stop operation signal to BCM through CAN communication.

When the BCM receives auto-stop operation signal, BCM sends wiper stop signal to IPDM E/R through CAN communication.

IPDM E/R stops wiper motor. Wiper motor will then stop wiper arms at the STOP position.
