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

DTC TROUBLESHOOTING CHART 

Is LOW 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 32,34,36,38: TIRE PRESSURE SENSOR TRANSMISSION FAILURE 

1. Check the indicated location to make sure the wheel is a TPMS type with the tire pressure sensor. 

DTC TROUBLESHOOTING CHART 

Is a TPMS type wheel with a tire pressure sensor mounted on the vehicle?  

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.
