Messing with Tacomas TSS System *PAYBACK TIME*

[@beaupopp1265]

I put a black wrap over my emblem about five months ago on my 2019 taco. No issues so far. The cruise control distance mechanism works fine.

[@RobMotive]

I was surprised that one layer of tape didn’t affect bit. More robust than I expected !

[@yezkaholic]

Have you have any issues at all? I want to put an emblem?

[@randomrebuilds]

Just got done lifting my taco. Turned out it was an even 2.5" on all 4 corners plus the bigger tires accounting for 4" in lift. (2) warnings went off - collision warning (TSS) and the vehicle stability control. Right after having it aligned, the front came down almost an inch and the taco was back to having the 1" rake in the back like OEM. There were no warnings on the dash best of all. Lesson learning - try to maintain 1" of rear rake when lifting to avoid the TSS from going off.

[@terrancetatum7599]

I've never had any problems with mine and I do like the system. But if I ever find myself in a storm of painters tape and aluminum foil, I'll know what to expect. LOL 😊

[@RobMotive]

Lol!!! That’s too funny! Just make sure you never crash into a Lowe’s!!!!!!😆😆

[@terrancetatum7599]

@@RobMotive - Okay you were right, I was wrong. My forward camera system failed this afternoon, on my way home from work. My windshield was only slightly dirty from showers the day before. I just turned it back on and it was fine the rest of the way. Never had any problem with it before. You've jinxed me! 😊

[@RobMotive]

Lol!! You see....I speak the truth!!😎

[@crawdad7305]

Yay for the 17 without all that expensive nonsense! Haha!

[@RobMotive]

There is something to be said for the old ways!!!!!😬

[@adeladahdah4418]

I would like to buy the trd pro grill insert for my 2019 tacoma. I hear lots of complains about the garnish interfering with the tss system. I really dont want to buy it from the dealership. Is crazy high. What do you think.

[@RobMotive]

I’ve never used the garnish. I have heard complaints though. 🤔

[@224evans]

I have a pro grill on my 2018 off road. Dealer checked my system due to recall, and I’ve not had any issues.

[@garypreisendorfer3668]

Can't wait to see what the 2020 has behind the grill!

[@RobMotive]

Me either! Hopefully not the same bandaid🤔

[@rcjward]

Apropos, since I got a false alarm beeping and telling me to brake due to headlight glair with my Honda last night. These systems are nothing but annoying.

[@RobMotive]

They are indeed!

[@rcjward]

RobMotive Looking forward to seeing the awesome sounding new blue Tacoma.

[@RobMotive]

Waiting impatiently over here!!😐

[@jones328]

Great video; I like your willingness to put the TSS to the test... Did you try to activate the radar cruise control while the sensor was covered? Just wondering what would happen.

[@RobMotive]

I did not. I’ll have to try that👍

[@josepha.graziano5232]

I was told that the TSS system would not work with a Bully Bar when I called several manufactures and Toyota.

[@RobMotive]

Depends on it it obstructs the sight path of the sensor🤔

[@rollee223]

Man Rob! I saw the title, and HAD to watch this one, as I totally HATE the TSS system! But I also noticed your truck only had 1600+ miles on it. Let me tell you about my experience with my 2019 TRD Sport. When I first bought it this past April 2019, during the first 2000 miles, the PCS warning light would come on, much like what you were making it do in this video. But it would come on for no reason, as the windshield was clean as well as the sensor cover. Very annoying! If I turned off the truck and restarted it, the PCS light would be off and things would work fine for weeks. BUT, after I hit 2000 miles, it seemed to clear up and never came on. That is, until October 4 2019, when I left the San Francisco Bay area, to drive to the East coast. About an hour into my drive, the PCS light came on, with message saying "PCS System unavailable, Clean Sensor". Well, I left at 1130pm at night, but still, there were no bugs on the sensor cover and the windshield was still clean. So why did it come on? I didn't stop until about 3 hours later when I got gas, so I cleaned the sensor cover then and after getting back on the road, the PCS light was out until about 30 minutes later, when it came on again, with same message. This continued ALL THE WAY across the United States for 5 days, until I arrived at the Outer Banks of NC on October 9th. I would say that on the entire trip across the country, the PCS Light was on about 90% of the trip, making the Toyota Safety Sense system, totally useless when I would need it most, on a cross country trip! I mean, man, I was pretty pissed about it, since it seems to be a big thing that Toyota promotes! On the morning of the 10th, when I went outside to get in the truck, it was covered with salt ocean spray, and I could hardly see out of the windows all around. AND YET, from that day forward, I got NO PCS OFF light, nor did I get any messages! The TSS system worked perfectly OK all the way back to the west coast! I can tell a difference too, since I have been back home, in how the PCS warning buzzer works just in riding around town. Right now, I would say it works as it is supposed to work, but it only started working as I said, when I got to the east coast, and at that time, the mileage was about 6700 miles! Now that I am back, and it just turned over 10,000 miles, it is working just fine. I told all of this to the dealer when I took it in for the 10,000 mile service, and he said that indeed, the TSS system is a "learning system", which is why it took so long to work as intended. I don't know if that is a crock or not, but I can say it is working now, at least, for the time being! I for one, wish I could deactivate or remove entirely, the whole dang TSS system, including the DRCC [Dynamic Radar Cruise Control], as that is hideous the way it works. It is totally annoying to have to push the CC button in and hold it for a couple of seconds, to activate the NORMAL CC, instead of just hitting the button and setting the cruise speed. So I just wanted to tell you that I TOTALLY RELATE to your feelings about the TSS system! Thanks Rob, again, for all you do!

[@RobMotive]

Thanks for sharing your experience with the system. Not sure why they told you it has a learning curve? First time I’ve heard that. Good that it seems to be working now for you👍

[@rollee223]

@@RobMotive They also said basically the same thing when I was complaining about the crazy transmission! It too, was pretty pathetic during the first 2000 miles, but then it seems to have settled down and performs actually quite well around town. In fact, I am getting better gas mileage around town with my 2019 TRD Sport than I did with my 1996 Tacoma! BUT, it was during this cross country road trip, that I discovered how I HATE this transmission on the highway! If you set your cruise control, which most people would do on a cross country trip, the thing is going to make dang sure it STAYS at whatever speed you set it at! I mean, if you set it at 65, and you begin to go up even a slight incline, the dang transmission will downshift 2 gears to 4th, and all of a sudden, instead of cruising along at 1800rpms at 65mph, the engine is now SCREAMING at me because it is now running 3500rpms because of the downshift, and as such, the gas mileage drops like a rock! The reverse happens when going downhill in some of those mountain areas, where they say something like "5% grade next 3 miles". On regular cruise control in the old days, the vehicle would just increase in speed while going downhill, but in this Tacoma, once again, it DOWNSHIFTS into 4th, so it uses the transmission to brake or slow down the vehicle in order to maintain the cruise control speed! Once again, the rpms jump to 3500, and gas mileage drops like arock, all while the engine is screaming! Another thing related to the transmission I noticed on this trip, is how speed radically affects gas mileage. When cruising through those states that have 75mpg speed limit, I noticed that gas mileage dropped dramatically to 20-21mpg. BUT, when cruising at 60-65mph, the gas mileage was 25-26mpg, which to me, for the truck, is pretty darn good! But that is a 20% drop in gas mileage, when going from 65mph to 75mph. I didn't think it would have THAT much of a dramatic effect! So in summarizing, I love the truck as far as comfort and styling, I mean, when I would come out of the various travel centers after getting gas and going to the bathroom, I would always notice how my truck was the best looking truck in the lot, which always made me smile! But I hate the TSS system and the transmission on the highway.

How about to replace the grill (pro grill) without turn on light sensor .... had to go back to the oem grill

[@adeladahdah4418]

Thank you!

[@RobMotive]

Thanks for watching 👍

[@dylansharer8089]

Well if its covered in snow, do you really want the truck braking for you while its snowing?

[@RobMotive]

Unless you’re on a plowed and salted freeway🤔

[@garydp9760]

Even if it did brake for you, the ABS will take over if the wheels start to lock up.

[@goprozack4255]

😂😂My tss has been screwing up from factory even with all the recalls and everything it still tells me to reverse when I'm the only one on the road 😂

[@RobMotive]

The system has become self aware and it toying with you....😬

[@goprozack4255]

@@RobMotive it absolutely is 😂but I have 12k miles on a 2019 toyota tacoma and so far so good besides that but it's no big deal. Just funny how they can't fix it but at least they try. Very cool system indeed but why reverse going forward over 70+mph I'll never understand.

[@LeftyMcgee808]

Could u still drive after the double covering on the grill? Or does the truck automatically stop randomly?

[@RobMotive]

Absolutely. The truck does not stop.

[@gearrunner]

I have to say, I’m really glad my truck doesn’t have that system.

[@RobMotive]

You’re lucky. I suppose I wouldn’t mind if it were reliable 😬

[@emtlao]

I just replaced my grill and the pre-collision light come on. Will the light go OFF by itself later if you drive long enough?

[@RobMotive]

I’d say not. Sounds like something is wrong😬

[@emtlao]

RobMotive what’s your suggestion?

[@RobMotive]

Makes sure you plugged the wiring back into the sensor. Make sure nothing is in front of the sensor like some type of aftermarket bumper piece). If all else fails, disconnect the battery for a couple of hours and reconnect. These are the only things that could be wrong that I’m aware of.

[@yezkaholic]

Hey Rob. Still get the occasional warning during cold weather. By lookimg at the sensor i noticed 3 pin holes. Was that a mitigating factor dealership did during the recall?

[@RobMotive]

I haven’t seen any holes🤔. Could be. They said moisture could get in the sensor and cause problems .

[@yezkaholic]

@@RobMotive i was told by another user that the 3 pin holes is one of the "fixes". Also on the Toyota announcements on one of your videos it mentions either use the plastic adhesive cover or apply a sensor with the pin holes

[@RobMotive]

Sounds good to me👍

[@arthurorourke7625]

why not unplug system from under grill?

[@RobMotive]

You could👍

[@albertlibricz1819]

TSS system on the new Camery malfunctioned and made a person crash into a tree and totaled the car.

[@RobMotive]

Wow! That’s terrible 😬

[@garydp9760]

And that's why the manual states NOT to rely only on the system. BTW, how did it "make" them crash, was it a Tesla?

[@chadkranats1452]

I hate it because when it rains and car passes me it will mess up and I had the recall done recalibrated.

[@RobMotive]

Yup...not great for the application Toyota is using it for for sure!!😐

[@paullund9738]

No Issues with mine so far.

That’s good. Nice to hear a positive experience 👍

[@M-.-Jones]

So glad my truck doesn't have any of this nanny state crap on it.

[@RobMotive]

Does yours have stop/start?

[@M-.-Jones]

@@RobMotive Has stop start yes. I wouldn't mind stop/start in an echo boost or 4cylinder, you can barely notice it. But on a V8 it feels like a tank when it restarts.

[@RobMotive]

That’s my number one dislike!! Can’t stand stop/start😡

[@M-.-Jones]

@@RobMotive I might install the stop\start eliminator at some point that basically reverses the function. By default its off and the switch turns it on.

[@RobMotive]

Good idea. I’ve seen it’s available 👍

[@Coryrad]

None of that bullshit should be on a truck. Period.

[@bryantcs0]

Remove the sensor, and video it.

[@RobMotive]

Huh?

[@bryantcs0]

Remove that camera by the rear view mirror, and then disconnect sensor in grill. Then remove black paint where camera is glued. It blocks visual.
