Auto Stop Operation
WARNING: This page is about a different car, the 2003 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.
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
- to the front wiper motor terminal E
- through body grounds E15 and E24.
Ground is also supplied
- through terminal 38 of the IPDM E/R
- to front wiper motor terminal P
- through terminal E of the front wiper motor and
- through body grounds E15 and E24.
When wiper arms reach base of windshield, front wiper motor terminals P and E are no longer connected. Then the IPDM E/R sends auto stop operation signal to BCM with CAN communication line.
When 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.
