Honda CR-V: DTC Troubleshooting

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

NOTE: If low tire pressure is detected, the control unit sets one or more of these DTCs, and turns on the low pressure indicator. If the low 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 OFF.

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 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 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 t ire location by the tire pressure sensor number (see page 18-51), then check the Tire 1, Tire 2, Tire 3, or Tire 4 Pressure Sensor Transmitter Status in the TPMS DATA LIST with the HDS and the TPMS sensor initializer tool.

NOTE: If Not defined is shown on the HDS, turn the TPMS sensor initializer tool OFF, rotate the tire 1/4 turn, then turn the TPMS sensor initializer tool ON, and try again. If Not defined is still shown, repeat the procedure in the previous sentence until a response is shown.

Is NORMAL indicated within one full turn of the tire? YES-Go to step 9.

NO-Check that the tire pressure sensor is properly mounted. If necessary, replace the appropriate tire pressure sensor.

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.
