Pressure check tool and method of operating the same

摘要

At a portable tool, vehicle identification information is requested from a vehicle and responsively received from the vehicle. Based upon the vehicle information, one or more tire pressure sensor activation/trigger methods or parameters are determined. The determined one or more tire pressure sensor activation/trigger methods or parameters are used to activate singularly or a plurality of tire pressure monitoring (TPM) sensors at the vehicle. Tire pressure information is responsively received from the activated TPM sensors.

主权项

1. A method for obtaining data from a tire pressure monitoring (TPM) sensor, the TPM sensor disposed at a vehicle wheel, the vehicle having a receiver disposed therein, the receiver being physically separate from the TPM sensor, comprising:
at a portable tool: requesting and receiving vehicle identification information from a label affixed or attached to a vehicle; based upon the vehicle identification information, determining one or more tire pressure sensor activation/trigger protocols and one or more Recommended Cold Pressures, the protocols effective to wake the TPM sensor from a sleep state to an active state; using the determined one or more tire pressure sensor activation/trigger protocols to activate one or more tire pressure monitoring (TPM) sensors at the vehicle; responsively receiving tire pressure information from the activated TPM sensors; determining by a controller of the portable tool whether the tire pressure information falls below any of the one or more of the Recommended Cold Pressures; wherein the tool interacts exclusively with the tire pressure monitor sensor and not the receiver of the vehicle.
