2006 Chevrolet Cobalt LS 2.2L No Communication
So, this Cobalt came into the bay after it had been
wrecked and repaired with a check engine light on with
about 20 codes including a PCM error code. We replaced the
pcm only to find a couple of communication codes. This is
were the real trouble starts.
