DTC 31, 33, 35, 37: Tire Pressure Sensor Low Battery Voltage

NOTE: This problem occurs when the temperature around the sensor is -40°F (-40°C) or less. Note that the diagnosis must be made in a place where ambient temperature is -40°F (-40°C) or more.

1. Test-drive the vehicle at 28 mph (45 km/h) or more for at least 1 minute.

Does the TPMS indicator go off?

YES - The system is OK at this time. Clear the DTC with the HDS.

NO - Go to step 2.

2. Check for DTCs with the HDS.
3. Note the tire pressure sensor(s) number by the indicated DTC.





4. Determine the affected tire location by the tire pressure sensor number.

Did each tire pressure sensor location respond to the TPMS initializer tool?

YES - Go to step 5.

NO - Check that the tire pressure sensor is properly mounted. If necessary, replace the appropriate tire pressure sensor.

5. Check the TIRE 1, TIRE 2, TIRE 3, or TIRE 4 PRESSURE SENSOR TRANSMITTER BATTERY in the TPMS DATA LIST with the HDS.

Is LOW indicated?

YES - Replace the appropriate tire pressure sensor.

NO - Check for loose terminals and poor connections at the TPMS control unit. If necessary, substitute a known-good TPMS control unit, and recheck.
