Ford Explorer 2011-2013

摘要

The body control module (BCM) of the 2011-2013 FordExplorer monitors the tire pressure in the four road tires with tire pressure sensors. The tire pressure sensors are battery operated and mounted to the valve stems. The instrument panel cluster (IPC) illuminates the TPMS warning indicator and the message center displays a message when a fault is present or when the tire pressure falls below the low pressure limit. The programmed tire pressure can- not be changed. NOTE: A scan tool can be useful in diagnosing TPMS concerns and may be used to verify if the TPMS sensors are transmitting accurate tire pressure data by comparing the proportional integral derivative controller (PID) tire pressure data in the BCM to the actual tire pressure using a digital tire pressure gauge. Each tire pressure sensor transmission is compared against a low-pressure limit (pressure listed on the vehicle certification label minus 25%, which will be about 6 psi to 9 psi).
