# Service bulletin 511440

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

Daimler Trucks North America LLC \(DTNA\), on behalf of its wholly owned subsidiary, Freightliner Custom Chassis Corporation, is initiating Field Service Campaign SF637A to modify specific model year 2021 Freightliner Custom Chassis manufactured September 17, 2019 through April 7, 2021. In a low voltage condition, the IP display may not come on when turning on ignition leaving drivers without a functioning instrument panel. This would only occur at startup and the instrument panel would function again if the key is cycled with normal voltage. The software will be updated to resolve the issue.
