Hello I will help you with your question,
If the pressure is correct, the sensors have not been replaced and the warning light is on the system will have to be relearned with a scanner to put the monitor into "learn" mode.
The procedure for learning the system is below
TPS (Tire Pressure Sensor) ID Registration Procedure TPS is assembled on each tire to check tire air pressure. This system only turns on warning lamp regardless of TPS position even if air pressure of one tire becomes less than warning pressure. So, Id registration is not necessary in case of rotation or replacement of tires. However, Id registration is necessary when shipping vehicles, TPS is replaced due to Sensor break/failure or Low battery, or Receiver is replaced.
The scan tool is a TECH 2 or Suzuki Diagnostic tool.
Let me know if you have further questions about this
