TPMS PID Definitions: Notes

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 vehicle speed is above 32.2 km/h (20 mph), the 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 PID displays SYSTEM FAULT.

• TPMS_STAT = LOW: If the BCM has detected at least 1 TPMS sensor reporting low tire pressure, the PID displays LOW.
• TPMS_STAT = ACTIVE: If the TPMS is functioning normally, the PID) displays ACTIVE.
