Just finished replacing the throttle body heater plate which was leaking. When I buttoned everything up it started fine but the hill descent light & TC lights were on and the green M & S lights kept blinking. Restarted several times but the same condition persists. Any explanation for this?

 

Is your battery fully charged? That kind of stuff can happen when you have a weak battery. If nothing else has changed while you did the TB heater, I’d start there before assuming it was something more serious.
