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

2003 Acura MDX TouringSECTION DTC 11, 13, 15, 17: Low Tire Pressure
NOTE: If low tire 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 indicator(s) come on due to true low tire pressure, and the customer corrects it before bringing the vehicle in, the DTCs will have been stored, but all the indicators will be off.
  1. If no tire indicators are on, retrieve the DTC(s). Check that the low-pressure sensor is properly mounted on the wheel of the indicated tire(s).

  2. Check the pressure of the indicated tire(s).

    Is there 176 kPa (1.8 kgf/cm 2  , 26 psi) or less? 

    1. YES  - Go to step 3.
    2. NO  - Go to step  5.
  3. Check for and repair the cause of air loss, and then inflate the tire to 220 kPa (2.2 kgf/cm2 , 32 psi) (see WHEEL ALIGNMENT ).
  4. Turn the ignition switch ON (II).

    Do the tire Indicators go off within one minute? 

    1. YES  - The system is OK at this time. Clear the DTC (see HOW TO CLEAR TPMS DTCS  ).
    2. NO  - Go to step 5.
  5. Check the tire pressure with the HDS. If no response 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 no response, repeat the procedure in the previous sentence until a response is shown.

    Is the tire pressure shown on the HDS monitor within 40 kPa (0.4 kgf/cm 2  , 6 psi) of the actual tire pressure? 

    1. YES  - Check for loose terminals and poor connections at the TPMS control unit. If necessary, substitute a known-good TPMS control unit and recheck.
    2. NO  - Replace the tire pressure sensor (see TIRE PRESSURE SENSOR REPLACEMENT  ).
