TPMS Parameter Identification (PID) Definitions
WARNING: This page is about a different car, the 2015 Ford C-Max. However, it is still accessible from the selected car via links, so may be relevant.
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.
