The Snap-on Tools Tire Pressure Sensor System Tool Kit, No. TPMS4, is a diagnostic tool that tests tire pressure monitoring sensors, captures sensor data and relearns tire pressure monitoring systems (TPMS). The TPMS4 features vehicle-specific prompts and reset procedures following tire rotation and sensor replacement. This tool features a daylight-readable, high-resolution display for reading PSI, ID, temperature, battery status and more. It determines whether a replacement sensor is needed, provides quick registration of new sensor locations after tire rotations and tests key FOBs for proper signal strength and battery condition. The kit runs on a Lithium Ion rechargeable battery and includes TPMS connect software to print sensor information, as well as access new software updates as they become available.
