FRONT WIPER AND WASHER SYSTEM WW-5 C D E F G H I J L M A B WW ● to CPU (central processing unit) located in IPDM E/R, ● through 15 A fuse (No. 71, located in IPDM E/R) ● to CPU located in IPDM E/R. With the ignition switch in the ON or START position, power is supplied ● to ignition relay, located in IPDM E/R, ● through 15 A fuse [No. 1, located in fuse block (J/B)] ● to BCM terminal 38, ● through 10 A fuse [No. 12, located in fuse block (J/B)] ● to front wiper reverse relay terminal 1, ● through 10 A fuse (No. 84, located in IPDM E/R) ● to front washer pump terminal 1 ● to front wiper motor terminal 4. Ground is supplied ● to BCM terminal 52 ● through grounds M16 and M70, ● to IPDM E/R terminals 38 and 51 ● through grounds E22 and E43, ● to combination switch terminal 12 ● through grounds M16 and M70. LOW SPEED WIPER OPERATION When wiper switch is in the LO position, BCM detects low speed wiper ON signal by BCM wiper switch read- ● from BCM terminals 39 and 40 ● to IPDM E/R terminals 49 and 50. When IPDM E/R receives front wiper request signal (LO), it turns ON front wiper low relay, located in IPDM ● through IPDM E/R terminal 23 and front wiper high relay and front wiper low relay ● to front wiper motor terminal 3. Ground is supplied ● to front wiper motor terminal 1 ● through front wiper reverse relay terminals 3 and 4 ● through grounds E22 and E43. With power and ground supplied, the front wiper motor operates at low speed. |
