Intermittent Operation
WARNING: This page is about a different car, the 2003 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.
Power is supplied at all times
- from BCM (input 2) terminal 49
- to combination switch terminal 2.
When the ignition switch is in ON or START position, and the front wiper switch is turned to INT position, the front wiper INT contact in the combination switch comes ON, and Power is supplied
- from combination switch terminal 6
- to BCM (output 1) terminal 47.
When BCM determines that combination switch status is front wiper INT ON, it performs the following operations.
- When BCM detects ON/OFF status of intermittent operation dial positions 1, 2, and 3 (in same way as wiper INT), it determines wiper dial position status.
- BCM calculates operation interval from wiper dial position and vehicle speed signal received from combination meter through CAN communications.
- BCM sends front wiper request signal (INT) to IPDM E/R at calculated operation interval.
When IPDM E/R receives front wiper request signal (INT), it turns ON internal front wiper relay. It then sends auto-stop signal to BCM, and conducts intermittent front wiper motor operation.
