There's always a chance that something got damaged when the fuses blow, however chances in this case are minuscule. Make sure the situation with the short circuit is resolved, replace the fuse and don't do any work, especially electrical, with the power source connected.

  • Alirigh thanks for the answer. Well gm told me if the check engine isnt on, There is nothing to the ecu. Also the Factory diagram show the concerned fuse and would mean the over volt or over amp would have stoped at the fuse. Mar 7, 2019 at 2:26
  • Normally the ecu is protected itself by fuses right ? Mar 7, 2019 at 2:28
