Low Tire Pressure/TPMS Indicator Does Not Comes On When The Tire Pressure Has Decreased (TPMS)

Diagnostic procedure

1. See general troubleshooting information "condition for data rejection, and case TPMS can not operate normally" (Even if a system is normal, there is a possibility that cannot detect low tire pressure) .
2. Do the gauge control module self-diagnostic function - Refer to: Gauges Self-Diagnostic Function (2013-15), or Gauges Self-Diagnostic Function (2016) .
3. Do the TPMS calibration .
4. Update the VSA modulator-control unit if it does not have the latest software . If the VSA modulator-control unit was updated and the symptom is still present, replace the VSA modulator-control unit - Refer to: VSA Modulator-Control Unit Removal and Installation, or VSA Modulator-Control Unit Removal and Installation (With ACC) (2016) .
