Loss of Communication DTC Cross-reference Chart
When an ECU is unable to communicate with the other ECUs on the CAN circuit, the other control units will set loss of communication DTCs.
-
Find the Transmitting Control Unit that is in the same row as all of the loss of communication DTCs retrieved.
-
Perform the input test for the transmitting control unit.

NOTE: In order for the MICU to verify the communication with the automatic lighting/rain sensor, after the battery terminal(s) have been disconnected, connect the automatic lighting/rain sensor 5P connector before reconnecting the battery terminal(s) and turn the ignition switch ON (II). Since only the automatic lighting/rain sensor unit is determined equipped or unequipped by the presence of communication, when the connector is disconnected, even the equipped vehicle is determined as unequipped.
