What is a CAN communication circuit?

So what exactly is CAN? It is a communication standard that allows the various modules and computers in a vehicle to talk to one another via a common “data bus” circuit in the wiring system. Think of it as a high speed party line that allows data and commands to zip back and forth from one module to another.

How do I fix my U0100 code?

Diagnosing a U0100 Code

  1. First, Check Your Battery. This may sound obvious, but check your voltage before you look at anything else.
  2. Check For ECM and TIPM/BCM Trouble Codes.
  3. Check the Wiring Harness.
  4. Check the CAN C Bus Connection.
  5. Check the PCM.
