DTC U12A5: General Description

Courtesy of HONDA, U.S.A., INC.

The electric power plant-controller area network (EP-CAN) transmits/receives pulsing signals to/from the control modules simultaneously by using two signal lines (H line and L line). When the information is not sent from the motor control module via the EP-CAN lines and this condition continues for a specified time or when the information sent from the motor control module is abnormal and this condition continues for a specified cycle, the powertrain control module (PCM) detects a malfunction and stores a DTC.
