Summary of Issue

Hendrickson's latest Tire Pressure Management System (TPMS) adjusts tire pressure based on axle load. If it is lowering the tire pressure an audible discharge of air may be heard. The system is operating as it should, but it may be misconstrued as a leak in the braking system.

Justification or Need

The new TPMS system allows for both inflation and deflation of the tires

Request for Action

Add language in possibly OP's 15 and OOS manual to detail this type of system
