DTC 22

DTC 21, 22, 23, 24: Abnormally High Tire Sensor Temperature

1. Make sure the tires have cooled down.
2. Turn the ignition switch ON (II).
3. Check the tire indicated by the DTCs you retrieved.

NOTE: An abnormal rise in the internal temperature of the tires can be caused by:
^ Excessive braking
^ Failure to release the parking brake (rear tires only)
^ Leaving the vehicle running while parked
^ Improper assembly of a wheel and tire





4. 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 5.

5. Read the internal temperature of the tire with the HDS.

NOTE: If the HDS screen shows not defined 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 not defined is still shown, repeat the procedure in the previous sentence until NORMAL is shown.

Is 176 °F (80 °C) or more 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.
