CAR CRAKNS OVER BUT NOT FIRING

on my car that kept saying DCL it was a cold solder joint on the circuit board where the conector plugs into the digital instrament cluster the problem would come and go all the time and have an anoying alarm sound.cheap fix if you have the time and a good quality electronics soldering iron and a steady hand use a magnifying eye loupe to find the bad solder conections they will be like a volcano shape or coroded looking downside you will have to remove the dash and disable airbag and 4 hands smaller the better hard to get conector back on the panel.i think its a layered board to.use caution putting cluster back together .
