Last update 22-04-2024
The washer fluid reservoir uses a magnetic sensor to detect the water level. This is a 2-wire sensor with only two signal states: ON or OFF. On means there's water in the tank, OFF means low level or no water. To remove and replace the sensor, one can use a plier.
Part Number: 31349235 sold on AliExpress The water tank pump has a 2-wire connector. See the pinout below for more info.
The washer fluid reservoir uses a 4-pin connector. 2 wires are used for the level sensor and 2 wires are used for the washer motor.
| PIN | Function | Wire colors |
|---|---|---|
| 1 | unused | |
| 2 | +12V DC washer motor | yellow w/ white stripe |
| 3 | common ground | black |
| 4 | +5V DC sensor signal | yellow |

ðĒ Fully tested and working
A green circle means the hardware electronics or the programming code was fully tested, each of its functionalities and capabilities. And it can be installed in a vehicle. Keep in mind this does not mean errors won't happen. As in everything related to electronics and software, there are revisions and updates. This open hardware is no different.
ðŊ Fully tested & working, no improvements necessary - already being sold online
ð Fully Open hardware \ source code
ðĪŠ There's better than this. don't use it
ð Fully closed hardware \ source code
âĄïļ fully tested and working, however, it is a dangerous solution to deploy
ðĄ Not tested. Working capability is unknown, it may work or not.
A yellow circle means the hardware electronics or the programming code was not fully tested, each of its functionalities and capabilities. This does not mean it not working, it simply means testing is needed before giving a green circle of approval.
ðī Fully tested but not working.
A red circle means the hardware electronics or the programming code was fully tested, and found some kind of critical error or fault. This means the electronics or firmware code cannot be used in a vehicle.
â Not started.
The hourglass means the hardware electronics or the programming hasn't started. Most likely because is waiting for the necessary test components needed for reverse engineering and also engineering of the new open solution.
