TPMS Parameter Identification (PID) Definitions

The BCM  monitors the TPMS  status. The current status can be viewed by accessing the TPMS  status Parameter Identification (PID): TPMS  _STAT using the scan tool. This helps identify the current system status and may aid in diagnosing the system. The Parameter Identification (PID) has 4 valid states:

• TPMS_STAT = SENSOR FAULT: If the BCM  has not received the tire pressure data from 1 to 3 TPMS  sensors for 20 minutes when vehicle speed is above 32.2 km/h (20 mph), the Parameter Identification (PID) displays SENSOR FAULT.
• TPMS_STAT = SYSTEM FAULT: If the BCM  has not received the tire pressure data from all 4 TPMS  sensors for 20 minutes when vehicle speed is above 32.2 km/h (20 mph), the Parameter Identification (PID) displays SYSTEM FAULT.
• TPMS_STAT = LOW: If the BCM  has detected that at least 1 TPMS  sensor is reporting low tire pressure, the Parameter Identification (PID) displays LOW.
• TPMS_STAT = ACTIVE: If the TPMS  is functioning normally, the Parameter Identification (PID) displays ACTIVE.
