DTC 23

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





1. Make sure the tires have cooled down, and then check the tire indicated by the DTC 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

2. 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 3.

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

NOTE: If not defined 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. If there is still no response, repeat the procedure in the previous sentence until a response is shown.

Is the internal temperature shown on the HDS 176°F (80°C) or more?
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.
