FRONT WIPER AND WASHER SYSTEM WW-5 C D E F G H I J L M A B WW 2006 Pathfinder LOW SPEED WIPER OPERATION When the ignition switch is in the ON or START position, and the front wiper switch is turned to the low posi- ● from BCM terminals 39 and 40 ● to IPDM E/R terminals 39 and 40. When IPDM E/R receives front wiper (low) request signal, it supplies ground to energize the front wiper relay. ● through front wiper relay ● to front wiper high relay ● through IPDM E/R terminal 32 ● to front wiper motor terminal 1. With power and ground supplied, the front wiper motor operates at low speed. HI SPEED WIPER OPERATION When the ignition switch is in the ON or START position, and the front wiper switch is turned to the high posi- ● from BCM terminals 39 and 40 ● to IPDM E/R terminals 39 and 40. When the IPDM E/R receives a front wiper (high) request signal, it supplies ground to energize the front wiper ● through front wiper relay ● to front wiper high relay ● through IPDM E/R terminal 35 ● to front wiper motor terminal 4. With power and ground supplied, the front wiper motor operates at high speed. INTERMITTENT OPERATION Wiper intermittent operation delay interval is determined from the combination of the intermittent wiper dial ● from BCM terminals 39 and 40 ● to IPDM E/R terminals 39 and 40. When the BCM determines that combination switch status is front wiper intermittent ON, it performs the follow- ● BCM detects ON/OFF status of intermittent wiper dial position. ● BCM calculates operation interval from wiper dial position and vehicle speed signal received through CAN ● BCM sends front wiper request signal (INT) to IPDM E/R at calculated operation interval. When the IPDM E/R receives a front wiper request signal (INT), it supplies ground to energize the front wiper AUTO STOP OPERATION When the wiper arms are not located at the base of the windshield, and the wiper switch is turned OFF, the |
