WIPER AND WASHER: WIPER AND WASHER SYSTEM: SYSTEM DIAGRAM
1. WIPER AND WASHER SYSTEM
(a) Various switches or sensors are shown as being inputs for the different systems mentioned in the section. Where direct electrical connections do not exist between components, signals may be carried across the different networks (BEAN, CAN) that exist on the vehicle. If a signal needs to travel from the CAN network to the BEAN network, or between different BEAN networks, the Gateway ECU allows the signal to travel between these different networks. Some of these different signals can be confirmed or inspected using the Techstream.
(b) The following system diagrams are intended to show the concept of operation, and may not precisely reflect the construction of the system on the vehicle.
Input and output signals of each ECU:
HINT
* Wiper operation is controlled by the main body ECU LH (cowl side J/B LH).
* The rain sensor controls the auto wiper function.
