id091900000200

1. When the wiper switch is placed in the INT position, the intermittent wiper relay is turned on and current flows to the windshield wiper motor, which is driven at low speed.

2. Based on the vehicle speed signal sent from the ABS (DSC) HU/CM, the intermittent wiper relay controls the timing is as follows:

  • Vehicle speed of 0 km/h:

  - INT volume max.-approx. once each 11.6 s
  - INT volume min. -approx. once each 4.2 s

  • Vehicle speed of 30 km/h and above:

  - INT volume max.-approx. once each 9.6 s
  - INT volume min. -approx. once each 1.1 s
