Tire pressure sensor check 1
-1. Note the tire pressure sensor(s) number by the indicated DTC.





-2. Do the tire pressure sensor location procedure to determine the affected tire location and relate it to the tire pressure sensor number Tire Pressure Sensor Location.

Did each tire pressure sensor respond to the TPMS tool?
-YES- Go to step 3.
-NO- Check that the tire pressure sensor is properly mounted. If necessary, replace the appropriate tire pressure sensor Service and Repair.

3. Tire pressure sensor check 2:

Tire pressure sensor check 2
-1. Check the TIRE 1, TIRE 2, TIRE 3, or TIRE 4 PRESSURE SENSOR BATTERY STATUS in the TPMS DATA LIST with the HDS.

Is LOW indicated?
-YES- Replace the appropriate tire pressure sensor Service and Repair.
