TPMS control module and low tire pressure warning light
TPMS control module receives signals from 4 tire pressure sensors, identifies each data by the ID code of each tire pressure sensor and uses the identified data to compare the air pressure in each tire with the specified value. When the tire pressure is judged as lower than the specified value (183.4 kPa), TPMS control module makes the low tire pressure warning light in the combination meter light up and stores the DTC in its memory. Also, when a faulty condition of the system is detected, TPMS control module makes the low tire pressure warning light in the combination meter flash and stores the DTC in its memory.
NOTE:
Only up to 4 ID codes of the tire pressure sensor can be registered in TPMS control module. Therefore, when a spare tire or any other sensor equipped wheel with tire is used as a running wheel, ID codes of all tire pressure sensors installed to 4 tires must be re-registered. When the vehicle is driven without re-registration of the ID codes, TPMS control module detects a faulty condition of the system and makes the low tire pressure warning light flash. For the procedure to register the ID codes of tire pressure sensors in TPMS control module, refer to REGISTRATION PROCEDURE FOR TIRE PRESSURE SENSOR ID CODE .
