Ladies and gentleman, first of all I'm an active duty service member stuck in Germany. My 2012 terrain was acting up today and typically the CEL came on. It is like 100$ just for them to scan my codes I can't pay that much. Is there ANY way to get the code with out a reader? Every thing is super expensive here and this is the only vehicle I have so time is of the essence. Please help I'm in desperate need TIA
