How TPMS Works

System Indicator

The TPMS (tire pressure monitoring system) has the low tire pressure indicator and the TPMS indicator.






The Low Tire Pressure Indicator

- If the system detects low pressure in any of the four tires, the low tire pressure indicator comes on.

- When this happens, inflate the air and test-drive the vehicle at 28 mph (45 km/h) or more for at least 1 minute, and the low tire pressure indicator will go off.

- If the control unit detects a problem in the system during an indication of low tire pressure, it turns off the low tire pressure indicator, stores the DTC(s), and turns on the TPMS indicator.

The TPMS Indicator

- If a problem is detected in the system, the TPMS indicator comes on.

- If low tire pressure and a problem in the system are detected, only the TPMS indicator comes on.

If the system is OK, the TPMS indicator and the low tire pressure indicator should come on when you turn the ignition switch to ON (II), and then go off 2 seconds later. If they don't, there is a problem with the system.

DTC 11, 13, 15, 17

If the system detects low pressure in any of the four tires, the low tire pressure indicator comes on, and the control unit sets one or more of these codes: DTC 11, 13, 15, 17. When the tire pressure returns to normal, and the TPMS control unit receives the normal pressure signal from the tire pressure sensor, the control unit turns off the indicator. However TPMS control unit still retains the DTC(s).

NOTE: It is necessary to test-drive the vehicle at 28 mph (45 km/h) or more for at least 1 minute so that tire pressure sensor transmits the signal.
