There’s definitely no bus to Kleine Scheidegg (no roads up there!), only a cog railway from both sides + a few cable car options in the vicinity.
You might also have searched for Grosse Scheidegg, which is another pass located east of Grindelwald. There is actually a road up there including a bus service during summer season. But that road is generally closed for private traffic and therefore not maintained (cleared from snow) at all during winter, so right now there is no bus service until approx. Whitsunday/Pentecost weekend. Thus searching for a connection to Grosse Scheidegg in the near future should also throw up some funny error messages…
