TPMS DTC Troubleshooting: 11, 13, 15, 17

DTC 11, 13, 15, 17: 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 pressure indicator and the appropriate tire indicator(s). If the low pressure and tire indicators 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. Turn the ignition switch to LOCK (0).

2. Make sure the tires are inflated to the specified tire pressure listed on the doorjamb sticker.

3. 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.


4. Check the tire pressure of the appropriate tire with the HDS.
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 rotating procedure 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, Service and Repair and recheck.

NO - Check that the tire-pressure sensor is properly mounted Replace the appropriate tire pressure sensor.. Service and Repair
