I have a CAT C3000 and i am getting the codes P3, P4, and P7. So there is no communication at the VCM, ECM, or MP. I am getting the LED Blinking on the back of the VCM, and it was the letter B confirming the codes on the dash. Was the fix a combination of a new ECM and harness? Any help would be appreciated.

Fact of the week
In March 2002, identical twins in Finland died on the same day in similar accidents within hours of each other. A 70-year-old man was killed by a truck while cycling; hours later, his twin brother was killed by a truck on the same road, about a mile away, before the family had been informed of the first accident.
