DTC U1205: Lost Communication with Motor Control Module: General Description
The integrated motor assist-controller area network (IMA-CAN) uses two signal lines, IMACANH and IMACANL, and it receives and transmits multiple signals simultaneously to/from multiple control modules.
When the information is not sent from the motor control module (MCM) through the IMA-CAN and this condition continues for a specified time or when the information sent from the MCM is abnormal and this condition continues for a specified cycle, the powertrain control module (PCM) detects a malfunction and a DTC is stored.
