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

NOTE: This problem occurs only when the temperature around the sensor is -40°F (-40°C) or lower, 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 00.
Does the TPMS indicator go off with one minute?
YES - The system is OK at this time. Clear the DTC with the HDS.
NO - Go to step 2.

2. Read the tire pressure sensor voltage with the HDS.

NOTE: If no response is shown on the HDS, turn the ignition switch OFF, rotate the tire 1/4 turn, then turn the ignition switch ON (II), and try again.





Is the tire pressure sensor voltage low?
YES - Replace the 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.
