S660 Seat Heater Failure
Summary of the thread
The seat heater in a 2017 Honda S660 is not functioning, and an error is stored in the system. A defective seat heating mat is suspected, but initial checks should include inspecting the fuses and wiring connections under the seat for any visible damage. If these components are intact, the heating mat itself is likely the issue, and professional diagnosis and repair may be necessary.

Thanks for the quick reply. I haven't checked the fuses or wiring. Where exactly are the fuses located, and what should I be looking for with the wiring?

The fuse box location is detailed in your owner's manual, typically under the dashboard or in the engine compartment. Consult the diagram for the seat heater fuse. Visually inspect the wiring harness under the seat for any obvious damage: cuts, chafing, or disconnected connectors. However, given the error code and lack of heat, the heating mat itself is the prime suspect. You'll probably need a workshop to diagnose this properly.

Okay, thanks for the confirmation. I'll check the fuses but will probably take it to the workshop then. They quoted me about 390€ for the repair, so looks like it's the heating mat, as you suspected.

A defective seat heating mat is likely, especially given the stored error. Have you checked the relevant fuses and wiring connections under the seat first? If not, this would be the first step.
