Rear Intermittent Wipe Variable Delay

Rear intermittent wipe variable delay
The rear intermittent wipe variable delay operation allows the driver to adjust the interval between wipes to suit local conditions. Rear variable delay operation only activates if the following conditions are met:
^ Ignition switch in position I or II.
^ Front wash/ wipe switch on intermittent.
^ Rear wipe switch is operated.

The BCU determines the desired delay interval based on the setting of the variable delay switch. The rear wash/ wipe delay is nominally twice as long as that of the front. This information passes from the IDM to the rear wiper relay and activates the rear wiper motor.

If the delay duration is decreased during operation of the rear wiper, the wipers immediately operate once and the delay cycle is reset.

If the delay duration is increased during operation of the rear wiper, the delay cycle is automatically increased by the BCU.
