Loss of Communication DTC cross-reference chart

WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.

When an ECU on the CAN circuit is unable to communicate with the other ECUs on the B-CAN and F-CAN circuits, the other control units will set loss of communication DTCs. Use this chart to find the control unit that is not communicating with the other control units on the CAN circuit.

  1. Find the Transmitting Control Unit that is in the same row as all of the loss of communication DTCs retrieved.
  2. Do the input test for the transmitting control unit.
