129 top contoller codes

[chronodeco]

I checked my top codes on our 1990 300SL this weekend. Pretty easy to do - my top and rollbar lights have been on for about a month now but everything still works so I am not in a panic to fix this. I got codes: 10, 16 and 23 and was able to remove 10 but 16 and 23 remain. I know what 23 is so I'm hoping that I don't need another controller. Could someone please advise on checking the # 16 - roll bar limit switch not retracted? I'd like to try to fix this first. I have read several previous posts on this but this code repair is not all that clear. Thanks, Craig
