Body Network System: Inspection: Notes

  1. The body network system consists of several ECUs that communicates via a CAN bus. The diagnostic tester is not directly connected to the CAN bus, but utilizes a one-wire communication line (K-line) that connects to a gateway in the IPM ECU.
  2. The IPM communicates with the diagnostic tester directly. But other units operate self diagnostic, input/output monitoring and actuator operation via the IPM using the CAN communication.
