DTC TROUBLESHOOTING 

DTC 11,13,15,17: LOW AIR PRESSURE 

1. Turn the ignition switch ON (II).  

2. Check which tire indicator is on. 

NOTE:

If low Air pressure is detected, the control unit will set one or more of these 
DTCs, and turn on the low pressure indicator and the appropriate tire 
indicator(s). If the low pressure and tire indicators come on due to true low 
Air pressure, and the client corrects it before bringing the vehicle in, the 
DTCs will have been stored, but all the indicators will be off.

NOTE:

If no tire indicators are on, retrieve the DTCs with the HDS.

DTC TROUBLESHOOTING CHART

3. Turn the ignition switch OFF.  

4. Check the pressure of the indicated tire. 

Is there 168 kPa (1.7 kgf/cm

2

 , 24 psi) or less? 

 

YES - Go to step 5. 

NO - Go to step 7. 

5. Check for and repair the cause of air loss, and then inflate the tire (see WHEEL ALIGNMENT ).  

6. Turn the ignition switch ON (II). 

Do the tire indicators go off within 1 minute?  

YES - The system is OK at this time. Clear the DTC with the HDS. 

NO - Go to step 7. 

7. Check the tire pressure of the appropriate tire with the HDS. 

Is the indicated tire pressure on the HDS within 40 kPa (0.4 kgf/cm

2

 , 6 psi) of the actual tire 

pressure?  

YES - Check for loose terminals and poor connections at the TPMS control unit. If necessary, 
substitute a known-good TPMS control unit (see TPMS INDICATOR OR TIRE(S) INDICATOR
(S) DOES NOT GO OFF, AND NO DTCS ARE STORED ), and recheck. 

NO - Check that the tire-pressure sensor is properly mounted. Replace the appropriate tire pressure 
sensor (see TIRE PRESSURE SENSOR REPLACEMENT ). 

DTC 21,22,23,24: TIRE PRESSURE SENSOR ABNORMALLY HIGH 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:

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.

4. Turn the ignition switch ON (II). 

Does the TPMS indicator go off within 1 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. 

Is 176°F (80°C) or more indicated?  

YES - Replace the appropriate tire pressure sensor (see TIRE PRESSURE SENSOR 
REPLACEMENT ). 

NO - Check for loose terminals and poor connections at the TPMS control unit. If necessary, 
substitute a known-good TPMS control unit (see TPMS INDICATOR OR TIRE(S) INDICATOR
(S) DOES NOT GO OFF, AND NO DTCS ARE STORED ), and recheck. 

DTC 31,33,35,37: TIRE PRESSURE SENSOR LOW BATTERY VOLTAGE 

1. Turn the ignition switch ON (II). 

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

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.

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.
