My Dealer-less TPMS Tire Change Story

[PittsburghJoe]

Well, we got a dumping of snow this weekend, so I was working on the car today. Swapped over onto the winter sets, pumped them back up to required pressure (44psi since they only barely make the load rating for the Kizashi at that pressure), came back and did the relearn and no more low pressure warning. TPMS without the dealership year 2.

I actually referred back to this thread to find the relearn procedure since I hadn't done it in so long. Got it on the first try and triggered all the sensors on the first shot too. It was a good day, although tiring!

Ok. I'm know I'm dumb but I want to make sure and get this right. In order to perform dealerless TPMS should I let the 5 psi out of the snow tires before I put them on the car, after or does it matter? Thanks again so much.

Letting 5psii out is what will trigger the tpms sensor. Once the car is in relearn mode, you need to trigger all 4 sensors within 3 minutes.

Ok. So would this be a proper order of steps?

1. Put on snow tires (these sensors were pingged at the dealer last year but my understanding is they won't be now that the all seasons were pingged in the spring.)
2. Put the car in relearn mode. How do I do that?
3. Let out 5 psi of all 4 tires within 3 minutes.
4. ???

Again sorry to be so thick but someone this is all not adding up as I go through the steps in my head.

2012 Suzuki Kizashi SLS TPMS Learn Sequence For Schrader EZ Sensor – Bridgeport 33000

NOTE: Multiple attempts to put the car into learn mode may be required. Turn the ignition OFF after each unsuccessful attempt.

1) Inflate tires to pressure on door frame placard
2) Turn ignition ON
3) Press driver’s door frame switch for interior light for 4 seconds and release
4) Press switch again for 4 seconds and release
5) Press switch again for 7 seconds and release
6) If successful the TPMS symbol next to the speedometer needle will begin blinking in a series of two quick flashes. The yellow exclamation point (!) light will go out if the "Service TPMS" message was previously displayed.
7) Quickly scan the LF, RF, RR, LR wheels in that order.
8) After last scan the TPMS symbol will stay on until the car is started.

I'm guessing you release the pressure in Step 7?

[SamirD]

Sorry for the delayed reply. Yes, elease the pressure in step 7. As each sensor is triggered, the number of flashes indicates how many sensors are left to trigger.

Step 8 is wrong. When it is done, the tpms light will remain solid for 5 seconds and then go out. If it continues to flash, the relearn isnt complete.

So an odd thing happened today while driving on the highway--service tpms lit up. Strange since i relearned the sensors already. Luckily i know all the tricks of relearning, so i did it again. Everything was fine for a while, but then again, service tpms lit up again. The front passenger sensor didnt trigger at first, so im suspecting its having issues. I never finished putting together a winter set with tpms, so im probably going to get a set of new sensors and then use my spare set in rotation with my existing tires to figure out which one is the bad one.

The tpms saga continues...

Won't your TPMS tool tell you which sensor is bad?

Some tools can read the battery level of some sensors. I don't think the kizashi sensors report battery life. The tools sees all the sensors, so I don't think it's bad, per se.

The funny thing is the tool triggers the sensor fine, hence the car is able to relearn them. But somewhere along the way, it's losing communication. Could be a low battery or weak signal as I didn't have this problem last winter, but I also did rotate the tires from their positions last winter.

Light is still on, and since we've gotten some decent snow and I saw someone ditch it yesterday in order to avoid hitting the car in front of them (which they still tapped), I'm going to relearn it again this morning. If it comes on again, looks like I'm going to be hunting down which wheel is the issue.

One thing I observed the other morning, but haven't seen anything in the service manual about is that the TPMS light will flash initially when the car is started before turning solid. I can't tell if there's a sequence of flashes there, but I wonder if it's trying to tell me something.

Looks like your experiencing a problem we will all be facing soon. I have been told that the TPMS batteries will begin to fail at about four years. I had found some aftermarket TPMS sensors that you can clone to the ID of your existing sensors. I plan to clone my existing sensors and put these sensors on a winter set of tires/rims. Changing winter and summer tire sets should be simple with not need to play with the TPMS system in your car. It has been some time since I discovered these sensors but I'm pretty sure they are are Schrader EZ-Sensor Bridgeport 33000.

Possibly. I didn't run into this issue last year, and these are not my original sensors, rather the genuine Suzuki sensors from a forum member in Canada.

I thought about using that system that clones the sensors, but then triggering the sensors was the tricky part of the relearn. Now, knowing that releasing air pressure can do that, the cloning system is probably the easiest way to be done with TPMS forever (except for when a sensor goes bad).
