Expert Insight: The P0601 Code Fix
As a technician, one of the most common codes I see on these 2004 GM trucks is P0601. This code specifically points to an internal memory failure within the original computer. There’s no way to repair it; the module must be replaced. Many owners waste time and money chasing other potential causes.
