T6.1 Tyre Pressure Monitoring System Activation (Indirect TPMS)

[Pauly]

Thats a good question, the work i have posted is based on vehicles available at that time which i think were all 2021ish models

I see no reason why it wouldnt work on all 6.1 models as long as there were no major changes (and im not aware of any)

Thanks @Pauly

This is the details for activating indirect TPMS on any T6.1 vehicle that didnt get it from the factory (huge credit to @mmi for his assistance on this)

Firstly we need to understand what TPMS is, there are two types :

Indirect TPMS - This uses the ABS sensors to measure wheel rotation speed and will give you a dash warning light if any one of the wheels starts to lose pressure (causing that wheel to rotate faster relative to the other wheels) no pressure measurement is taken from the tyres

Direct TPMS - This uses a sensor inside each wheel to directly measure the current tyre pressure and temperature and displays these values inside the vehicle, a drop in pressure in any wheel/s will trigger an alert on the instrument cluster and the infotainment screen


Secondly we need to take backups of the vehicle configuration before we begin, always always take a full scan of the vehicle and save somewhere safe so you have a baseline of settings and things can be reverted if needs be
T6.1s use adaptions channels more than ever as well as basic coding so its important to do a full auto scan AND admaps so you have all the info to fall back on, it does take a little while to complete these scans but it will be a well spent half hour if you run into problems in the future doing this or any other mod !

To activate TPMS we are going to start with module 03 ABS

Enter module 3 and then go into coding/long coding helper
In here we need to change the five values below, its important that all five are changed at the same time, changing them one at a time does not work and will generate an error
Byte 0 Bit 5 - 0
Byte 6 Bit 3 - 0
Byte 8 Bit 2 - 0
Byte 14 Bit 4 - 0
Byte 17 Bit 4 - 1

save the changes and exit
dont worry if faults appear they will sort them selves out when the rest of the programming is done

--------------------------------------------------------------

Now we are going to move on to module 17 instruments

Enter module 17 and then go into coding/long coding helper
Find Byte 4 Bit 0 and turn on (put a tick in the box)

save the changes and exit

--------------------------------------------------------------

Lastly is module 5F infotainment

Enter module 5F and then go into adaptions
All should show 'not active' so need to be changed to the below values (its quite a long list so use the search box to shortcut to 'rdk' and '0x07' channels)

ENG122227-ENG117541-Car_Function_Adaptions_Gen2-menu_display_rdk = activated
ENG122227-ENG117543-Car_Function_Adaptions_Gen2-menu_display_rdk_over_threshold_high = activated
ENG122229-ENG117704-Car_Function_List_BAP_Gen2-tire_pressure_system_0x07 = activated
ENG122229-ENG117705-Car_Function_List_BAP_Gen2-tire_pressure_system_0x07_msg_bus = Extended data bus

Thats it, everything can be saved and exited, after all changes are made reset any fault codes that are showing

Hey Pauly, do you know if this can be done via OBDeleven?

If you know how to code with it then i assume yes but have never tried/used it

I think the important bit will be the ability to change multiple values at the same time, if you can do that i would say yes
