Good morning All,
Good morning All,
I've recently fitted Winter wheels onto my 2010 3,6 TDV8 and purchased 4 sensors (from Amaz..) with the same part number as the OEM (LR070840 / GX631A159AA).
After that, when I start the car I get the usual message "Pressure level adjusted for light load". Well...
After 15/20 minutes driving, message "TPMS system default" on dashboard display.
The message disappears after one min. and comes again 15/20min after.
I tried to relearn ID sensors on ODB with deflated tyres: no effect
I checked the TPMS sensors with an Autel Maxi TPMS TS508 and all the sensors seems OK: pressure, temperature, battery level.
The question is:
I have a DTC displayed onto the Autel: B1C9000
Checked everywhere and the best answer founded is "Auxiliary driving lamp relay coil circuit"
I don't understand what the Auxiliary Driving Lamp is neither the relation between this relay and the TPMS system and I can't cancel this DTC.
Has anyone encountered this DTC ?
Thanks a lot for your answer !

Any chance there's a mismatch with the frequency of the new ones and the spare under the loadspace? 2012 Supercharged L322

Hello TorontoDee,
In fact the Autel TS508 is able to relearn the new sensors ID into the ODB.
A friend checked the ODB with his professionnal computer and he confirm the new ID are well into the ODB.
What is strange is the message when I start the car "Pressure level adjusted for light load".
It let me suppose that all is OK in static.
Do you know the frequency of the ODB send the signal to the sensors (some minutes, 10 minutes or more?)
It seems the sensors do not receive the message from ODB.
Where the transmitter is located ?
