Auto Stop Operation

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

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

• From IPDM E/R terminal 33
• To front wiper motor terminal 1, in order to continue wiper motor operation at low speed.

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

• To IPDM E/R terminal 38
• Through front wiper motor terminals 5 and 2
• Through grounds E9, E15 (all models) and E24 (with MR20DE).

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

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

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