Lost Communication with ECM / PCM (U0100,U0140,U0142,U0155,U1117)
DESCRIPTION
These DTCs are stored when there is a CAN communication malfunction between the
certification ECU (smart key ECU assembly), ECM, main body ECU (multiplex network
body ECU) or combination meter assembly, and data from the option connector (bus
buffer ECU) cannot be received.
