    I replaced the ECM on my 99 Volvo D12 and all was well for the first couple of weeks. Now, starting 4 days ago when I start first thing in the morning I am getting two codes. My first is a low voltage and second is cab controller data erratic. I thought this might be battery related. However I have checked batteries and all checks out. I forgot exact codes and am away from truck today. Any idea on how to correct this? I will get the exact codes.
