TPMS

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 ON (II).

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 FR, FL, RR, or RL in the TPMS DATA LIST with the HDS.

NOTE: If the HDS screen shows UNDEFINED for sensor status, turn the ignition switch OFF, rotate the tire 1/4 turn, then turn the ignition switch ON (II), and try again. If UNDEFINED is still shown, repeat the rotating procedure until NORMAL is shown.





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.
