System Description INFOID:0000000004306905
• Front wiper relays (front wiper relay, front wiper hi gh relay) are located in the IPDM E/R (intelligent power
distribution module engine room).
• Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input terminals.
Terminal combination status is read by BCM (body control module) when switch is turned ON.
• BCM controls front wiper LO, HI, and INT (intermittent) operation.
• IPDM E/R operates wiper motor accordi ng to CAN communication signals from BCM.
OUTLINE
Power is supplied at all times
• to ignition relay, located in IPDM E/R, from battery directly,
• through 40A fusible link (letter g, located in fuse and fusible link box)
• to BCM terminal 70,
• through 30A fuse (No. 39, located in IPDM E/R)
• to front wiper relay located in IPDM E/R
• through 15A fuse (No. 52, located in IPDM E/R), and
• through 20A fuse (No. 53, located in IPDM E/R)
• to CPU located in IPDM E/R.
When ignition switch is in ON or START position, power is supplied
• through ignition relay (located in IPDM E/R)
• to front wiper relay (located in IPDM E/R), and 1. IPDM E/R E45, E46 and E48 2. BCM M18 and M20 (view with glove
