The Jeep Wrangler’s tire pressure monitoring system (TPMS) uses radio and sensor technology to monitor air pressure levels. Sensors are mounted to each wheel as part of the valve stem and broadcast tire pressure data to a central receiver circuit inside the Wireless Control Module (WCM). If a low pressure condition exists, the WCM will send a request to illuminate the low pressure warning light and to sound a chime.
