Symptom Chart: Tire Pressure Monitoring System

Diagnostics in this information assume a certain skill level and knowledge of Ford-specific diagnostic practices. REFER to ENGINE CONTROLS - DIAGNOSTIC METHODS (EXCEPT DIESEL & HYBRID) for information regarding Ford-specific diagnostic practices.

SYMPTOM CHART

Condition	Possible Sources	Actions
A module does not respond to the scan tool	Fuse Wiring, terminals or connectors Communication network concern TPM module	REFER to SYMPTOM CHART: COMMUNICATION NETWORK .
The TPMS warning indicator is never or always on	Communication network concern IPC	REFER to DIAGNOSTIC ROUTINE Q : The Tire Pressure Monitoring System (TPMS) Warning Indicator Is Never or Always On.
TPMS warning indicator is on continuously and the message center displays LOW TIRE PRESSURE	Spare tire currently in use sensor(s) TPMS sensor(s) Tire pressure not set to specifications listed on the VC label TPMS sensor	REFER to Diagnostic Routine G : Tire Pressure Monitoring System Warning Indicator is on Continuously and the message center displays Low Tire Pressure.
TPMS warning indicator is on continuously and DTCs are present	Not all TPMS sensors are installed TPMS sensor(s) not trained TPMS sensor(s) Intermittent TPMS operation due to RFI TPM module wiring TPM module BCM wiring BCM	REFER to Diagnostic Routine F : Diagnosing Radio Frequency Interference Faults.
The BCM will not enter TPMS sensor training mode	Stoplamp switch concern Ignition switch concern VSS concern BCM	REFER to Diagnostic Routine H : The Body Control Module Will Not Enter TPMS Sensor Training Mode.
One or more TPMS sensors do not train and DTCs are not present	TPMS sensors RFI	REFER to Diagnostic Routine I : One or More Tire Pressure Monitoring System Sensors Do Not Train and No DTCs are Present.
One or more TPMS sensors do not train and DTCs are present	TPMS sensor(s) Vehicle communication issue Intermittent TPMS operation due to RFI TPM module wiring TPM module BCM wiring BCM	FOLLOW the diagnostics for the DTC(s) retrieved.
