=== 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)

RSDN is a signal from the PHEV-ECU, appears to be referred to as "Rear Motor Shutdown Circuit", there is a corresponding fault - [http://mmc-autoelectric.org.ua/manuals/eur/outlander/2014/54/html/M154923250001700ENG.HTM P1048] which has the following diagnostic information:

Which all suggests that RSDN is a form of hardwired shutdown signal from PHEV ECU to REMCU. Probably needs to be pulled low or high. Would suggest using as safety circuit on an EV.  


There is another signal from PHEV-ECU to Front motor controller called MSDN. Likely serves a similar purpose.
==== 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).[https://openinverter.org/forum/viewtopic.php?p=27785#p27785]

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 [1]

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).[2]

CAEH & CAEL - CAN Communication

Standard CAN bus, Baudrate xxxkBaud??

Diagnostic Codes [3] - *LINK BROKEN*

P1048 - Rear motor shutdown circuit [4]

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)
