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
_Control_Wiring_(2019_Model).png)
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
Authentication
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.
