Example: For wiper dial position 1

Using combination switch reading function, BCM detects ON/OFF status of intermittent operation dial positions 1, 2, and 3.

When combination switch status is as listed below, BCM determines that it is wiper dial position 1.

• Intermittent operation dial position 1: ON (Continuity exists between combination switch output 3 and input 1.)
• Intermittent operation dial position 2: ON (Continuity exists between combination switch output 5 and input 1.)
• Intermittent operation dial position 3: ON (Continuity exists between combination switch output 4 and input 2.)

BCM determines front wiper intermittent operation delay interval from wiper dial position 1 and vehicle speed, and sends wiper request signal (INT) to IPDM E/R.
