Int (Intermittent) Operation
Wiper intermittent operation delay interval is determined from the intermittent wiper dial position inputs. During each intermittent operation delay interval, the BCM sends a front wiper request signal to the IPDM E/R to operate the wipers.
When the ignition switch is in the ON or START position, and the front wiper switch is turned to the intermittent position, the BCM detects a front wiper (intermittent) ON signal by means of the BCM wiper switch reading function.
BCM then sends front wiper (intermittent) request signal through the CAN communication lines
- From BCM terminals 39 and 40
- To IPDM E/R terminals 40 and 41.
When BCM determines that combination switch status is front wiper intermittent ON, it performs the following operations.
- BCM detects ON/OFF status of intermittent wiper dial position
- BCM calculates operation interval from wiper dial position.
- BCM sends a front wiper request signal (INT) to IPDM E/R at calculated operation interval.
When IPDM E/R receives the front wiper request signal (INT), it supplies ground to energize the front wiper relay. It then sends auto-stop signal to the BCM and conducts intermittent front wiper motor operation.
