# Service campaign NCU \- 2024040008

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

Mercedes\-Benz AG, the manufacturer of Mercedes\-Benz vehicles, has determined that on certain MY21\-23 C\-Class and S\-Class vehicles \(206, 223 platform\), the software for the ISA control unit may not correspond with the latest series production configuration. The possibility exists that the function of the ISA may not be restricted with an active Malfunction Indicator Lamp. MBUSA will conduct a service campaign. An authorized Mercedes\-Benz dealer will update the ISA control unit software in the affected vehicles.
