| 09-045-23 | 2024-01-04. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. 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. |
