Wiper Dial Position Setting
WARNING: This page is about a different car, the 2008 Infiniti M45 and 2008 Infiniti M35. However, it is still accessible from the selected car via links, so may be relevant.
Front wiper intermittent operation delay interval is determined from a combination of 3 switches (intermittent operation dial position 1, 2, and 3) and vehicle speed signal.
After each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.
WIPER DIAL POSITION SETTING
| Wiper dial position | Intermittent operation interval | Combination switch | ||
|---|---|---|---|---|
| Intermittent operation dial position 1 | Intermittent operation dial position 2 | Intermittent operation dial position 3 | ||
| 1 | Short | ON | ON | ON |
| 2 | ON | ON | OFF | |
| 3 | ↑ ↓ |
ON | OFF | OFF |
| 4 | OFF | OFF | OFF | |
| 5 | Long | OFF | OFF | ON |
| 6 | OFF | ON | ON | |
| 7 | OFF | ON | OFF | |
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 and vehicle speed, and sends wiper request signal (INT) to IPDM E/R.
