DTC U0164: IMA-CAN Malfunction (A/C Compressor Driver-Powertrain Control Module (PCM)): 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 powertrain control module (PCM) cannot receive information sent via the IMA-CAN for a set time or more, a malfunction is detected and a DTC is stored.
