Loss of Communication DTC cross-reference chart

WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.

When an electronic control unit (ECU) on the CAN circuit is unable to communicate with the other ECUs on the CAN circuit, 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. BUS OFF and Internal Error Codes
