System Description: Notes

• 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.
