Each TPMS antenna receives radio frequency signal output from the TPMS transmitter, the TPMS receiver interprets the signals and detects abnormal-ity of tire pressure and/or the system, and the TPMS warning light illuminates or flashes to alert.

When the road tire pressure is low, it sends a warning sig-nal causing the TPMS warning light to be illumi-nated. When the TPMS has problems, it sends a warning signal causing the TPMS warning light to The TPMS transmitter includes a roll switch that senses tire rotation. The TPMS receiver can determine which tires are rotating (road tire) and stationary (spare tire). For 3 seconds after the ignition switch is turned to the ON position, the TPMS receiver illuminates the TPMS warning light to check any breaks in TSB Revisionbe flashed. the TPMS warning light circuit.GENERAL DESCRIPTIONWHEEL AND TIRE31-4 By connecting the scan tool to the data link con-nector, data stored in the TPMS receiver (data of tire pressure and tire pressure sensor ID, the alarm status and warning history, etc.) can be dis-played and the tire pressure sensor ID can be registered.TPM
