I read the manual TWICE for this.
I searched on SRM issues and found a couple of old threads but none of them was resolved.
I was entering a freeway and suddenly this warning light was on and noticed the synchro rev was not working.
I checked the wire switch behind the "frog face" and the white plug was connected properly.
If anybody had the same issue in the past and found the way how to fix this please chime in. Thanks!
