DTC 11, 13, 15, 17:

Tire Low Air Pressure

NOTE: If low tire pressure is detected, the TPMS control unit sets one or more of these DTCs, and turns on the low tire pressure indicator and the appropriate tire indicator(s). If the low tire pressure and tire indicators come on because of low tire pressure, and the client corrects it before bringing the vehicle in, the DTCs will be stored, but all the indicators turns 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 RF, LF, RR, or LR TIRE PRESSURE in the TPMS DATA LIST with the HDS, and compare it with the 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 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 Service and Repair, and recheck.�

NO -

Check that the tire-pressure sensor is properly mounted. If mounting is OK, then replace the appropriate tire pressure sensor Service and Repair.�
