Description
This dtc is output when a communication error occurs between the transponder key amplifier and transponder key ecu. Some possible reasons for the communication error are: 1) 2 or more ignition keys are positioned too close together, or 2) noise is occurring in the communication line.

Diagnostic trouble code chart
Hint:
If no abnormality is found when inspecting parts, check the
skid control ecu and check for poor contact at the ground
points.
If a dtc is displayed during the dtc check, check the
circuit for the dtc listed in the table below. For details of
each dtc, refer to the page indicated. ...

Check dlc3
Check the dlc3:
the power steering ecu uses can (iso11898-1)
and iso9141-2 for communication protocol. The
terminal arrangement of the dlc3 complies with
sae j1962 and matches the iso9141-2 format.
