Hi, this TPMS light drive me crazy!
TPMS always light on.
1. Tire pressure is 35.
2. Checked the sensors, they are ok, battery and they show the right pressure.
3. GM garage says OBD code is C0550.
4. Try to disconnect anti theft component (module), it is control the remote door lock also. My car is from south Korea 5. VIN: KL1CJ6ED7FC787942 6. Spark LT 1.2L 2015, CJ6ED
5. Google search says it maybe the Car Door Lock module (He is response for TPMS also). Anyone knows where is this component?

My TPMS light came on the whole time my tire was being 'worked on' when I was driving on the spare I bought, so I wouldn't have to sit & wait whilst the new tire was being sourced. Spark tires always seem to need to be ordered--not in stock in my suburban location. So, if the TPMS that is on the tire isn't linked to the car's system, and your car remembers another TPMS that is no longer on the car, you will get this light on the dash. It could be that the tire dealer 'forgot' or messed up setting up the TPMS when you got the tire. You can tell when they're doing it. The horn honks.
