Tire Pressure Monitoring System (TPMS) PID Definitions
WARNING: This page is about a different car, the 2014 Ford Explorer. 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 PID :
TPMS_STAT using the scan tool. This helps identify the current system status and may aid in diagnosing the system. The 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 the vehicle speed is above 32.2 kmh (20 mph), the PID displays SENSOR FAULT.
- TPMS_STAT = SYSTEM FAULT If the BCM has not received the tire pressure data from all 4 sensors for 20 minutes when the vehicle speed is above 32.2 kmh (20 mph), the PID displays SYSTEM FAULT.
- TPMS_STAT = LOW If the BCM has detected that at least 1 TPMS sensor is reporting low tire pressure, the PID displays LOW.
- TPMS_STAT = ACTIVE If the TPMS is functioning normally, the PID displays ACTIVE.
