Lincoln Aviator: Tire Pressure Monitoring System (TPMS) / Description and Operation - Tire Pressure Monitoring System (TPMS) - Overview
Overview
The BCM uses tire pressure sensors to monitor tire pressure. The sensors use radio signals to transmit the tire pressure to the RTM. The RTM sends the information to the BCM over a LIN.
The tire pressure sensors are battery operated and mounted to the valve stems.
The 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.

Removal
NOTICE:
During the removal of components, cap, tape or otherwise
appropriately protect all openings to prevent the ingress of dirt or
other contamination...
Inspection
NOTE:
Do not use a caustic cleaning solution or a wire brush to clean the pistons or damage can occur.
Clean and inspect the (1) ring lands, (2) pin bosses,
(3) skirts and the (4) tops of the pistons. If wear marks, scores or
glazing is found on the piston skirt, check for a bent or twisted
connecting rod...
