DTC 11, 13, 15, 17: Tire Low Air Pressure

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

1. Turn the ignition switch to ON (II).
2. Check which tire indicator is on.

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





3. Turn the ignition switch to LOCK (0).
4. Check the pressure of the indicated tire.

Is there 175 kPa (1.8 kgf/cm2, 25 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.
6. Turn the ignition switch to ON (II).

Do the tire indicators go off within one minute?

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

NO - Go to step 8.

7. Turn the ignition switch to ON (II).
8. Check the RF, LF, RR, or LR TIRE PRESSURE in the TPMS DATA RIST with the HDS, and compare with measured actual tire pressure.

NOTE: If the HDS screen shows UNDEFINED for sensor status, turn the ignition switch to LOCK (0), rotate the tire 1/4 turn, then turn the ignition switch to ON (II), and try again. If UNDEFINED is still shown, repeat the procedure in the previous sentence until NORMAL is shown.

Is the indicated tire pressure on the HDS within 40 kPa (0.4 kgf/cm2, 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, and recheck.

NO - Check then the tire pressure sensor is properly mounted. Replace the appropriate tire pressure sensor.
