# Service bulletin 09\-001\-24c

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

Some customers may experience a “Telematics Malfunction” message in the instrument cluster with DTC U3000:04\-TCU \(Telematics communication unit internal malfunction\) stored in memory. This is caused by improper control software of the telematics communication unit \(TCU\). To eliminate this concern, the control software of the TCU has been modified.
