SM5 Telematics Malfunction
Summary of the thread
A 2012 Renault SM5 owner experienced a telematics malfunction, indicated by an emergency call system error message and warning light. Initial troubleshooting, including checking fuses and performing a system reset, failed to resolve the issue. A suggestion to inspect cable and plug connections led to the discovery of a corroded connector, which was cleaned by a workshop, successfully clearing the fault.

Thanks for the tip. Where exactly is the telematics unit located in the SM5? And battery is fine, new about a year ago so voltage is correct.

Without the specific vehicle configuration, pinpointing the exact location is tricky, however it is probably near the fuse box. Given the symptoms and the fact that a system reset didn't resolve it, I'd advise getting it to a workshop. They can diagnose the wiring more thoroughly. If it is a bad connection, get ready for a bill around 95€.

Appreciate the advice. Turned out to be a corroded connector, as you suspected. Workshop confirmed, cleaned it up, and fault's cleared, total price was exactly 95€. Thanks again.

That sounds like a potentially defective connection. Have you checked the cable and plug connections to the telematics unit? A loose or corroded connector could trigger those symptoms. Is the car's battery healthy?
