Renault megane 3 TPMS

[GrecoDelToro]

Hi all,

I am trying to figure out a TPMS problem with my phase 2 Megane 3 car.

DDT4ALL has returned crazy logged data and I am not 100% sure what it is telling me is the fault.

It can see the IDs but suggests these are historically logged but with odd data readings for inflation and temperature.

I think I've pulled two codes from the car but is there a way to relate them for an OBD code?

You can't clear the DTC so its logged permanently and know it is as the dash has been telling me for ages.

I have 38206 - default antenna ext left - general electrical failure - circuit short to ground or open.

And 38194 - VSC bcm optical sensor - general electrical failure - circuit short to ground.

The latter I think is related to a cruise control stability control that is now possibly sorted.

Anyone able to help? DDT4ALL is all I have been able to get to read the car, Renolink is useless. Can Clip at the dealer said there was nothing wrong.

Uses maybe last release ddt4all and last db

Thanks for the reply. My build version is 3.0.6, is that the latest?

https://github.com/cedricp/ddt4all/releases/tag/v3.1.1 and get last db in discord (click badge discord in readme)

Thank you. Let me try this later.

Connect pc to internet for install (python3 need network to get somme dependecies) after install DDT4ALL work's in offline mode if you want

This may be an issue.

A newer database is not necessary for an older vehicle model.
When reading fault codes using the DDT database, it is important to know that all fault codes are generally displayed—including those that are not applicable to the specific vehicle model or ECU version.
This occurs because the same ECUs are installed in different vehicle models with varying equipment configurations.
Renault workshops use CLIP for diagnostics because they have a fault code filter list specifically tailored to the ECU version.
Consequently, only faults relevant to the vehicle are displayed, and these codes are resolved using an elimination process based on the corresponding diagnostic documentation.
Pyren3, PyCLIP3, and DroidClip utilize the CLIP database.

I have not had chance to do anything this evening.

I will try and plug in again tomorrow.

Looking at my screenshot from yesterday I can see that the DDT4ALL can see the wheel IDs and has archived data of 3000 psi plus for each wheel and 200⁰C temperature but not communication.

I am trying to figure out if there is a problem with the UCH or if there is an antenna separate to the UCH or if its a relearning problem.

If you disconnect the battery they will work for 24 hours. That's it.

I can see the link above mentions changing the parameters so they work for 6 months. Which is an okay work around but if the UCH is the problem id rather send it away for repair so they work as intended.

I will log back in tomorrow if I get chance.

You can send the files elm_ddt.txt and ecu_ddt.txt to the address in my user profile.

Still no luck solving this.

I can't pull a DTC from the TPMS. I can only locate the DTCs that tell me there isna problem with the VSC/Cruise control, which there is and one for the door lock antenna in the boot.

I can see the reverse parking sensor module isnt talking to the car so can conclude that is indeed dead.

So... how do I turn the TPMS off? I think it is my only option now. Not happy about it as I want them working but it just isn't giving me the data I want to see. Just tells me they're there and have silly data like 3000 bar and 205ºC

Batteries are fine in them and the tyre shop says they report data with an RF scanner. I dont think this is a relearning problem.

Ah interesting, no assistance is needed if no log files are provided for review and the fault diagnosis is not performed on with Clip basis.

The photos show an opened ECU file for the Zoe Phase 1 and a file for Master III. Under these conditions, ECU configurations should now be changed. Good luck ;-)
There isn't even a single photo showing these implausible values.
