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

WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If low tire pressure is detected, the TPMS 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 because of a low tire pressure, and the client corrects it before bringing the vehicle in, the DTCs will be stored, but all the indicators turns off.

Turn the ignition switch to LOCK (0).
Make sure the tires are inflated to the specified tire pressure listed on the doorjamb sticker.
Test-drive the vehicle.
Does the low tire pressure indicator go off?

YES -The system is OK at this time. Check for and repair the cause of air loss.

NO -Go to step 4.
Turn the ignition switch to ON (II).
Check the RF, LF, RR, or LR TIRE PRESSURE in the TPMS DATA LIST with the HDS, and compare with measured actual tire pressure.
NOTE: If UNDEFINED is shown on the sensor transmitter 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 displayed, repeat this procedure until NORMAL is shown.

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 CONTROL UNIT REPLACEMENT ), and recheck.

NO -Check that the tire pressure sensor is properly mounted. If the mounting is OK, then replace the appropriate tire pressure sensor (see TIRE PRESSURE SENSOR REPLACEMENT ).
