DTC U0073/42 - Control Module Communication Bus OFF

DTC U0100/65 - Lost Communication with ECM / PCM

DESCRIPTION

The translate ECU inputs the signals from the ECM via the CAN communication system.





HINT: For CAN communication malfunctions, after the malfunction is determined using the translate ECU, the results are sent to the skid control ECU. In total, this takes 7 seconds.

INSPECTION PROCEDURE
