Code U1205 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 Battery Condition Monitor (BCM) module detects a malfunction and when BUS-OFF is not detected after the time to detect BUS-OFF has passed, a DTC is stored.
