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 -4 °F (-20 °C) or more.

1. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.

Does the TPMS indicator go off within one minute?
YES - The system is OK at this time. Clear the DTC with the HDS.

NO - Go to step 2.


2. Check the RF, LF, RR, or LR TIRE PRESSURE SENSOR BATTERY VOLTAGE in the TPMS DATA LIST with the HDS.
NOTE: If UNDEFINED is shown on the sensor transmitter status, turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode, rotate the tire 1/4 turn, then turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode, and try again. If UNDEFINED is still displayed, repeat the procedure in the previous sentence until NORMAL is shown.





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

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