System Description: Notes
WARNING: This page is about a different car, the 2003 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.
- All front wiper relays (HI, LO) are included in IPDM E/R.
- Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input terminals. Terminal combination status is read by BCM when switch is turned ON.
- BCM controls front wiper LO, HI, and INT (intermittent) operation.
- IPDM E/R operates wiper motor according to CAN communication signals from BCM.
Power is supplied at all times
- through 50 A fusible link (letter F, located in fusible link box) to BCM (body control module) terminal 7
- through 30 A fuse [No. 74 located in IPDM E/R (intelligent power distribution module engine room)]
- to front wiper relay [built in IPDM E/R (intelligent power distribution module engine room)]
- through 15 A fuse [No. 73 located in IPDM E/R (intelligent power distribution module engine room)]
- to CPU (central processing unit) in the IPDM E/R (intelligent power distribution module engine room).
When the ignition switch ON or START position, power is supplied
- through 10 A fuse [No. 1 located in fuse block (J/B)]
- to BCM (body control module) terminal 35
- through 10 A fuse [No. 80, located in IPDM E/R (intelligent power distribution module engine room)]
- to front wiper relay [built in IPDM E/R (intelligent power distribution module engine room)] and
- to front wiper high relay [built in IPDM E/R (intelligent power distribution module engine room)]
- to CPU (central processing unit) in the IPDM E/R (intelligent power distribution module engine room)
- through 10 A fuse [No. 87 located in IPDM E/R (intelligent power distribution module engine room)]
- through IPDM E/R (intelligent power distribution module engine room) terminal 18
- to combination switch terminal 14.
Ground is supplied
- to BCM (body control module) terminal 8
- through grounds E13, E26 and E28
- to IPDM E/R (intelligent power distribution module engine room) terminals 14 and 45
- through grounds E13, E26 and E28
- to combination switch (wiper switch) terminal 12
- through grounds M14 and M78.
