• When the rear wiper relay turns on, current flows to the rear wiper motor due to a control signal from the microcomputer and the wiper operates continuously.
• When the rear wiper switch is returned to the OFF position, the auto-stop function activates and the wiper stops at the park position.

• As a result, current (2) flows at 10 s intervals causing the rear wiper to operate intermittently.
• When the rear wiper switch is moved to the OFF position while the wiper is operating, the rear wiper motor performs an auto-stop and stops in the park position.
