# Service bulletin CBR\-2494\-19 202606

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

The VN\(4\)'s electrical architecture relies on multiple ECUs, each handling specific functions. To ensure seamless operation and peak system performance, it is essential that all ECUs run the same software version \(Software Baseline\). This is accomplished by installing a complete software baseline, which is delivered via service pack.
