TPMS Data FMX003/1

Telematics Question
1

Would it be possible to add TPMS data from OBD for supported cars ?

For example the Ioniq5 OBD PID config for TPMS ( Source )

| Name | ShortName | ModeAndPID | Equation | Min Value | Max Value | Units | Header |
|----|----|----|----|----|----|----|----|
| 001_Tire Pressure Front Left | FL | 0x22C00B | e/5 | 0.00 | 120.00 | psi | 7A0 |
| 001_Tire Pressure Front Right | FR | 0x22C00B | j/5 | 0.00 | 120.00 | psi | 7A0 |
| 001_Tire Pressure Back Left | BL | 0x22C00B | o/5 | 0.00 | 120.00 | psi | 7A0 |
| 001_Tire Pressure Back Right | BR | 0x22C00B | t/5 | 0.00 | 120.00 | psi | 7A0 |
| 001_Tire Temperature Front Left | FL | 0x22C00B | f-50 | \-40 | 65 | C | 7A0 |
| 001_Tire Temperature Front Right | FR | 0x22C00B | k-50 | \-40 | 65 | C | 7A0 |
| 001_Tire Temperature Back Left | BL | 0x22C00B | p-50 | \-40 | 65 | C | 7A0 |
| 001_Tire Temperature Back Right | BR | 0x22C00B | u-50 | \-40 | 65 | C | 7A0 |

Good day,

Thank you for writing it to us.

TPMS is not a standard OBD-II PID — Tire pressure is not part of the standard OBD-II diagnostic parameter set (SAE J1979). It’s typically transmitted on the vehicle’s internal CAN bus as a manufacturer-specific parameter.

  1. CAN-based TPMS reading is possible — For devices with CAN data reading capability (like FMC150, FMC650, FMx150, FMx250 or LV-CAN200/ALL-CAN300 with external CAN adapter supported tracker), TPMS data can be read if the vehicle model has been reverse-engineered and tire pressure is included in the supported parameters list.

  2. Check the supported vehicles list — The Teltonika Wiki publishes the supported vehicles list for FMx150/FMx250 devices, which details exactly which parameters are readable per vehicle model. Tire pressure would need to be listed there for the specific car.

    Here is the link to the supported list:FMX150 supported vehicles - Teltonika Telematics Wiki
