Front Intermittent Wipe Variable Delay

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

The BCU receives the front intermittent wipe signal from the front wash/ wipe switch. The BCU receives a separate signal from the variable delay switch, determines the delay interval from the front wash/ wipe switch position and passes it on to the IDM. The IDM energises the front wiper relay to activate the front wiper motor.

If the delay duration is decreased during front variable delay operation, the wipers immediately operate once and then the delay cycle is reset to the new duration.

If the delay duration is increased during front variable delay operation, the delay cycle is automatically increased by the BCU.
