Rain Sensing Wiper Upgrade

[Oakstone]

I’m looking to do the same by adding the CCM and getting adaptive cruise (less the intelligent part because I also don’t have the built-in connected navigation). You can add the speed limit sign recognition now if you want, it’s all based on what the camera up by the rear view mirror sees. I find it pretty handy because it catches signs that I often miss.

I’ve actually never used the easy mode, but I’ll check it out and see if any of the options available match up with what I changed to enable the wipers.

Oh interesting! I didn't know I could enable just the speed sign recognition. I'd also love to know the modules those settings live in (easy mode if possible).

SCCM

So I added my rain sensor today but when I added your SCCM line of 724-02-01 XXXX XCXX it always throw a DTC error...

If I use the "Rain Sensor" under Forscan SCCM (with the naming system - not "as built") and choose enable. It works fine. Not sure if others may come across this as well.

@Oakstone I checked easy mode tonight and the IPC and APIM both show rain sensing wipers enabled, however the SCCM disagreed and seemed to still show disabled. I’m not sure I’d rely entirely on easy mode to make the changes. The same goes for traffic sign recognition, I found conflicting enabled/disabled settings in easy mode between the IPC, IPMA, and APIM. My traffic sign recognition is working despite what the easy mode suggests. I think you’re best off changing the as built values directly, then you can make note of exactly what was changed. I have a spreadsheet that I log each change per each individual module and I add comments to the cell if the changes produced the desired effect. If something goes wrong I can always load my original backup as built values and make my changes again. Or if I suspect a particular line that I changed was wrong, I also note the original string in the spreadsheet and can go back to what it was before the change. It’s not too bad changing the as built values, typically just one letter or number. I read the line at least three times and cross check it with what I’ve written down to make sure it’s the right digit in the right place before hitting write. I also only write one line at a time, even if it’s in the same module. This helps if you make a mistake, so you’re not writing everything at once and have to go back and try and find your mistake among all the lines of you were off by one.

What are your stock as-built values for that string?

 

[TJSparky]

These are my stock as built.

724-02-01 4A28 - 7809 - 21

When I enabled "Rain Sensor" it changed too...

724-02-01 4A28 - 7849 - 61

With no DTC's afterwards.

Do you show a DTC with yours using the "C" value on SCCM?

I'm showing no DTCs at present. My initial string was 4A27 7809 24. My updated string is 4A27 7C09 --. Did you verify there is power to the rain sensor plug up by the mirror?

Ok thanks! I was able to get things like auto windows and silent mode both working and on the display using just easy mode so I might just peek at all three of the modules and flip some settings to see if it works. Worst case I can revert and go as built.

Like you, I have been keeping track of my settings changes in a spreadsheet.

Thanks again!

@TJSparky I didn’t see that last part. So with the easy mode change in the SCCM, your rain sensing wipers work? This may be a slight strategy difference between 2021 models and 22-23. I came up with my changes based on a comparison to a 2023 Tremor that has rain sensing wipers as the majority of the SCCM was the same, particularly that line 724-02-01 matched 4A27 7X09 —, where the X was C on the tremor and was the only difference. For 2021 models (I checked my old 2021 and it matched your as-built for 724-02-01) there is an 8 instead of 7 at 4A2X, the X is a rain sensor module configuration (SCMRainSensorID_cfg) according to the Forscan spreadsheet but doesn’t show any possible values or what they would do. So perhaps the XXXX XX4X — is the correct change for 2021 models. That 4 seems to enable “SCMRainSensing_cfg” without any other impacts to the other variables that digit controls. If it’s working as expected with no DTCs, I’d go with that. I think that change would also be applicable for anyone with an as-built for 724-02-01 that begins with 4A28, but further testing on other trucks would need to be done to really confirm.

I still need to test it but no rain is expected here in Seattle for a long time. Weird huh!!! Lol!
I will try the hose on the windshield and see if that works. I’ll report back on the results.

So I gave this a shot and also had the same DTC when I edited it manually. When I changed the xxxx-xCxx and got the DTC, I also checked my simple as-built and the option for Remote Start had been enabled, when it wasn't before. I did enable the rain sensor in the SCCM via the simple menu and that did change my xxxx-xxXX value to 49, which makes sense, as that just enables the option it looks like, however the option that throws the DTC looks to actually enable the sensor.

I looked at the infotainment website and their kit includes the sensor, a new wiper stalk, and a harness that plugs into the sensor and then runs all the way down to the SCCM. My guess is for some reason, the harness that is up there is not connected on my truck, I didn't check for voltage, but I assume that's why they include the harness instead of having you plug into the factory connector. Maybe @Jesse-Infotainment can shed some light on this?

The other possibility is that the xxxX-xxxx number (SCMRainSensorID_cfg) needs to be changed, but since the forscan sheet has no info on that, I don't know where to go. I will say mine is a 7, I tried 8 and still got the DTC.

Also be aware that just because everything looks like it should work, I don't think they will actually sense rain without the xxxx-xXxx value being correct. When I didn't change that, and just enabled the easy way, everything looked correct, no DTC's and the option was enabled in my vehicle menu, but the wipers just operated as they normally do, which I would assume if there is no rain they should not wipe when enabled, but they did on mine.

You’re correct in how the stalk controls their operation with rain sensing enabled. Mine is currently set to the “mist” setting (slowest) and the wipers don’t wipe until there’s rain on the windscreen.

Maybe our setup does require the stalk to send power to the plug??? I ordered one to see if that is what it needs.

It's possible, I did kind of think this might be too good to be true. Keep us posted

I did notice my truck had this fuse in the engine compartment area too. Tanish 5 amp fuse.

The video from infotainment site had no plug in the mirror area like ours which is why I think a plug is included in the kit they sell.

sEEMS THE LATE 22 STALKS WORK without the Auto stalk. When I originally did mine I tried and got a DTC for the Switch. So I installed the new stalk and they worked then. I was made aware by @riderryan92 he did this without the stlk. He has a late 22.

Also not all of the plugs at the windshield are live. They are all there but not all wired completely.

Its hit or miss. Only way to really know is to try it.

Thats why We sell it complete. We cant continue to try we sell it and know it will work
