Washer fluid sensor enable / help Mazda 3 (EU)

I want to install a washer fluid sensor in my car.

The factory wiring diagram is included with the windscreen washer fluid sensor connected to the "2S" input of the FBC module.

For low liquid level, switch on the switch lock and the "2S" input of the FBC module to the ground.

I plugged the "2S" of the FBC module into the ground, but there was no low level warning on the IC and MZD monitors.

How do I activate this feature??

Thx! :)

@Radioactive:
Interesting - I also want to add the washer fluid-level sensor to my 2016 EU CX-5 (FW 56.00.513C EU), because the connector for the sensor to PIN 2S and ground already exists. But sensor itself, grommit and hole for it are missing. I tested the same way as you did... but I also do not get the level warning (not in MZD & not in instrument-display). Keep me posted, if you find a solution - I will do the same.

As far as I know the old models without MZD had an LED-Light in the instrument, which lighted up - perhaps this worked in the earlier days... but with MZD and instrument lcd-display (at least at my cx-5) it does not work. Perhaps something has to be programmed in the FBCM or MZD.

Edit1: Please read this thread - it seems as if there is no solution for showing the indicator in the instrument or MZD (for cars with MZD). Others already tried with technicans.

Edit2: I will continue the topic of trying to program the IC (instrument cluster) module for the washer-fluid level sensor in this thread.

Edit3: Programming works - see here. But I have not installed it yet.

I also want to replace my small 2,5 liter washer tank with the large 4 liter one and install the sensor @ my CX-5. In my small tank I would have to drill a hole with the correct diameter - and thats a little too tricky for me. That`s why I chose the large tank. I think that the larger tank always has an additional hole for the headlight cleaner washer motor, which has to be sealed or filled with the motor. This hole has a grommet, which I plan to seal with strong glue (like this).


The part numbers I plan to order are:

KD3567488 Sensor
KD3767491 Grommet for Sensor
KD3567481 4L-Tank
KD5367491 Grommet for headlight cleaner washer motor (which I do not want to install, but have to seal it)

Perhaps this part link also helps you somehow.

And here you can find how to change the tank @ a CX-5. And here how to remove the front bumper @ a CX-5. Perhaps it`s the same at other cars.

Today I received the ordered products (list in post #7) for my CX-5. Luckily the hole for the headlight cleaner washer motor in the tank is not open. So the grommet for headlight cleaner washer motor seems to be not necessary. In a first bathtub test the closed hole and the grommet around the sensor were both waterproof. I measured approx. 5.1-5.3 liters and approx. 200-300 ml after the sensor should signal low level. After installation I report again. Please remember that parts for a Mazda3 might be different.

Today I removed the small washer tank and installed the big one with new washer liquid level sensor in my cx-5:



Hints:
- Check before buying parts if sensor connector is pre-installed
- Check before buying parts if programming is possible - otherwise no message in the instrument appears.
- Washer motor is pretty tight in its hole. Use gloves and pull with force.
- All 3 screws can be removed - the tank is hold in place by nothes
- Ratchet extension is helpful (min. 10-12 cm)
- I drained the old liquid via the top hole of the tank and removed the washer motor afterwards
- Check grommets after installation
- Be careful with filling the tank - not only the blue was liquid - also the white - so do not overfil the tank
- I did not disconnect the negative term of the battery. And I checked with an empty tank if the IC message showed up - while the front bumper with its parking sensors was removed. Thus DTCs in PSM_MZ module showed up - delete them with ForScan after the front bumber is installed again.

Thanks to everyone who helped to make this project possible!

And it's work :)

Thank you all for posts and infromation

I don`t know exactly. Check if you already have the sensor connector in your car near the washer tank, bypass the connector and try to program the IC values to see in instrument if it`s possible. Then check if there is a cx-3 version with a (larger) tank with sensor to buy the correct parts for it. I only found part list of cx-3 2016 here - and this tank is different from mine in cx-5 (mentioned above).

See post #22 and post #30 in this thread. Old/original numbers/values are often different. If the old/original numbers of your IC module are different (check via Forscan), please post your original numbers of 720-01-01: xx-xx-xx-xx-xx-xx. Otherwise you can take the ones from the mentioned posts above. Always make a backup via Forscan of original values/data before editing.

At that photo/from that angle/perspective it might look like as if there is a sensor already at the old (small) washer tank, but it was not (at least not at my car). What looks like a sensor is only a blind plug/connector for storing/holding the connector/cable (which is already there due to the cable harness). And at my small washer tank there was no pre-marked/-perforated area for drilling a hole for the sensor - see following pictures:

Do you know where is best area to drilling a hole for the sensor?

I would not recommend drilling a hole in the small washer tank, as I did not find a suitable area at a lower "water" level. I have been in the basement right now and checked it and made some photos for you (one motif with flash and the same without it). I would recommend to buy a washer tank which has the hole already - e.g. the one I mentioned earlier. I assume that there are also small ones with hole, but why buy a small one, if you can have a big one - for those check online or with your dealer.
