# Service bulletin FSB 728\-001

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Electronically Controlled Suspension \(ECS\) Level Sensor Bracket, Replacement, In some MACK CXU trucks built between 06/01/2012 and 08/31/2014, the Electronically Controlled Suspension \(ECS\) level sensor may generate a M150 S13 F3 Diagnostic Trouble Code \(DTC\). An M150 S13 F3 DTC causes the suspension to lock into the blocked mode which may cause damage to the shock brackets, leveling sensor rod and arm.
