Vehicle Topology

Rear Motor Inverter (REMCU) is on EV-CAN with the following modules:

  • PHEV-ECU (Also on CAN-C, gatewayed through ETACS-ECU to CAN-C-Mid)
  • Front Power Drive Unit
  • Onboard charger/DC-DC Converter
  • A/C Compressor
  • Electrical Parking Driver Unit
  • Battery Management Unit

Can Bus Topology [10]

PHEV-ECU Handles the whole hybrid system management including drive mode, system torque distribution and battery management

Wiring diagram to the right.

It would appear that there are 4 unused pins on the Vehicle Connector (D-211).

IGCT - ECU control power supply voltage

IGCT appears to be main ignition control relay - 12V

This is the supply voltage for the REMCU and should be supplied with battery voltage when turned on.

RSDN - REMCU shut-down signal

RSDN is a signal from the PHEV-ECU and is referred to as "REMCU shut-down signal" as part of the "Rear Motor Shutdown Circuit". It seems to be the equivalent of the MSDN signal from the PHEV-ECU to the Front Motor Controller. The RSDN signal could be used as a safety circuit. In normal operation, it should be pulled to low (1V or less).[11]

CAEH & CAEL - CAN Communication

Standard CAN bus, Baudrate 500KBaud??

Diagnostic Codes [12]

P1048 - Rear motor shutdown circuit [13]

The PHEV-ECU stores diagnosis code No. P1048 when the rear motor shut down circuit fails.

Check the wiring harness between PHEV-ECU (RSDN terminal) connector and the rear EMCU (RSDN terminal) connector.

Communication Protocol

CAN Bus with fallback to LIN and K-Line according to service manual


The REMCU does not appear to require authentication with other modules, meaning it is a good candidate for stand-alone use from this point of view.

However, If one wished to take the whole Hybrid system including the PHEV-ECU for an EV conversion, this would be more challenging as the PHEV-ECU appears to require authentication with the OSS-ECU (One Touch Start ECU) and the KOS-ECU (Keyless entry)

Inverter Phase Connections

Based on information within the Service diagrams [14] the following HV phase connections have been identified on the inverter.
