Tire Pressure Monitoring

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

NOTE: If low tire pressure is detected, the control unit sets one or more of these DTCs, and turns on the low tire pressure indicator. If the low tire pressure indicator comes on due to true low tire pressure, and the customer corrects it before bringing the vehicle in, the DTCs will have been stored, but the indicator will be off.

1. Turn the ignition switch to LOCK (0).
2. Check the pressure of all four tires.

Is there 168 kPa (1.7 kgf/cm2, 24 psi) or less?

Yes - Go to step 3.

No - Go to step 5.

3. Check for and repair the cause of air loss, and then inflate the tire.
4. Test-drive the vehicle at 28 mph (45 km/h) or more for at least 1 minute.

Does the low tire pressure indicator go off?

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

No - Go to step 6.

5. Turn the ignition switch to ON (II).
6. Check for DTCs with the HDS.
7. Note the tire pressure sensor(s) number by the indicated DTC.





8. Determine the affected tire location by the tire pressure sensor number.
9. Check the TIRE 1, TIRE 2, TIRE 3, or TIRE 4 AIR PRESSURE in the TPMS DATA LIST with the HDS, and compare it with the actual measured tire pressure.

Is the indicated tire pressure on the HDS within 40 kPa (0.4 kgf/cm2, 6 psi) of the actual tire pressure?

Yes - Go to step 10.

No - Replace the appropriate tire pressure sensor.

10. Clear the DTC with the HDS.
11. Test-drive the vehicle at 28 mph (45 km/h) or more for at least 1 minute.
12. Check for DTCs with the HDS. Is DTC 11, 13, 15, or 17 indicated?

Yes - Go to step 13.

No - If any other DTCs are indicated, troubleshoot the appropriate DTC. If no DTCs are indicated, the system is OK at this time.

13. Clear the DTC with the HDS.
14. Turn the ignition switch OFF.
15. Install a known-good TPMS wheel.
16. Memorize the tire pressure sensor ID with the HDS.
17. Test-drive the vehicle at 28 mph (45 km/h) or more for at least 1 minute.
18. Check for DTCs with the HDS. Is DTC 11, 13, 15, or 17 indicated?

Yes - Replace the TPMS control unit.

No - Replace the original tire pressure sensor.
