DTC U1206: IMA-CAN Malfunction (Powertrain Control Module (PCM)-Battery Condition Monitor (BCM) 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 battery condition monitor (BCM) module through the IMA-CAN for a specified time continuously or when the information sent from the BCM module is abnormal and this condition continues for a specified cycle, the powertrain control module (PCM) detects a malfunction and a DTC is stored.
