Continental TPMS (Suzuki) - blinking led - where to find error codes / what means long blinking?

[kenwawa01]

Hi!
My problem is long and have long history but I will try to be very short (thus some simplification might happen).

I have the following problem with Suzuki Vitara S 2017 - it's based on Continental tpms module and Continental sensors thus it might happen that some experience from other cars with Continental systems (Kia, Hyundai, Mitsubishi, Honda, Toytota, BMW, Audi, Renault, Citroen, Nissan etc. might be helpful although its worth remember that non in all models Continental solutions were used).

Short version:

What tpms led blinking with long on and short off and that's repeat for 10-12 km means?

What kind of parameters are transferred from tpms programming/triggering tool to sensors in Continental system?

Long version:

case 1:

When trying to make automatic re-learn with genuine Continental tpms sensors I have after approx. 10-12 km of driving a message Service TPMS and car refuse to accept new sensors.

In DTC I have the following error then:

B1A11 Auto Tire Pressure Sensor ID Conde Learning Not complete Test: Complete Type FF00/20

(it's the most common code, sometimes this additional type field at the end is slightly different).

case 2:

When trying to make manual tpms reset and storing sensors id in car computer/tpms module (wirelessly with tpms sensor triggering with tpms activation tool), the procedure is successful with long tpms led on for 5 sec at the end which means: success.

case 3:

When trying to make saving ids through ODB cable, it's also successful.

more:

However (!) in case 2 and 3, when turning the engine on I have the following blinking (with case 1, sensors id are not stored in tpms module thus there is message "service tpms"):

• just after ignition on I don't have any warning message but for led I have: "short on, short off, short on, long off" and that pattern (or similar) repeats through 1-2 min. (code "22"? code "23"? or "11"? or "32"? or "123"? - the "blinked" code seems to be partially random)
• after some short driving I have: "long on, short off" and that pattern repeats until approx. 10 km
• next for short time I have "short on, short off, short on, short off, short on, long off" and that pattern repeats for 1 km of additional driving (perhaps even less) (code "3"?)
• next for short time I have "short on, short off, short on, long off" and that pattern repeats for 1 km of additional driving (perhaps even less) (code "2"?)
• next for short time I have "short on, short off" and that pattern repeats for 1 km of additional driving (perhaps even less) (code "1"?)
• next led is fully off, without any warning message, and the tyres pressure usually is displayed with some small delay but usually not for all tyres at the same time but tyres are "added" within 1-2 minutes until I have all tyres successful read (at the end the system displays the pressure for all tyres at once)

Then the systems works ok even if I drive ex. 100 km, no any problems. However if I turn off the car for 15-20 minutes and turn on again, the problem will repeat.

If I connect through ODB2 with diagnostic software, tpms sensors seems to work since the first seconds (without this 10-15 km delay). There are no any errors in case 2 and 3 (for automatic learning there is this B1A11 error but for sure I delete it immediately).

Does anyone know the tpms blinking messages for Suzuki Vitara? (or for other similar cars?)

Im guessing that there migh be the following reasons:

1. Incorrect tpms triggering sequence (despite successful id's store in car computer/tmps module) - might it be different for Vitara S than for normal Vitara (they use different tpms modules - mine is 39530-79M0)

Do you know what kind of parameters are sent within triggering sequence to sensor in Continental system?

Are there any parameters like: maximum delay in sending message when detecting movement or preamble expected or tires size?

Have you seen any project similar to rtl_433 but focusing on triggering sequence sent to tpms sensors?

2. Incorrect tpms sensors behaviour (accelerator problem and delay in sending messages?)

3. Initially the garage when I went, used the tpms triggering tool with incorrect sequence and they also changed tyres order (RF and LR tires were exchanges). Might it be that tpms module keeps the errors internally without being seen in DTC log? If yes, how to "delete/reset" tpms module errors?

4. Do you perhaps know if Continental S180052024 sensors have truck mode or any special mode (at first glance it seems that not but...)?

Thanks for help and suggestions!
