Description And Operation

DIGITAL NETWORKS 

The vehicle features an electrical/electronic architecture called Next-Generation. Data transmission between the various ECUs in the Next-Generation architecture occurs through the following digital networks:

• CAN-C1 (high-speed 500 kb/s)
• CAN-C2 (high-speed 500 kb/s)
• CAN-BH (medium-speed 125 kb/s)

These networks and their subnetworks are protected by a Security Gateway Module (SGM).

CAN-C1 

The ECUs interconnected by the CAN-C1 are:

• BCM (Body Control Module)
• DLC (Data Link Connector)
• IPC (Instrument Panel Cluster)
• ETM (Entertainment Telematic Module - Infotelematic Module VP2 with Nav or VP4)
• ORC (Occupant Restraint Control - Airbag module)
• RFH (Radio Frequency Hub Module)
• DTCM (Drive Train Control Module - Transmission Module)
• ESM (Electronic Shifter Module - Automatic transmission selector lever module)
• ABS (Anti-lock Braking System Module)
• ACC (Adaptive Cruise Control Module)
• TCM (Automatic Transmission Control Module)
• ECM (Engine/Powertrain Control Module)

CAN-C1 reaches the DLC multiple diagnosis connector.

The 120-ohm terminal resistors of the CAN-C1 are located in the BCM and in the ECM.

CAN-C2 

The CAN-C2 manages the data which is exchanged at high speed between the ECU modules of the vehicle chassis.

The control units interconnected by the CAN-C2 are:

• ABS (Anti-lock Braking System Module)
• BCM (Body Control Module)
• ESL (Electric Steering Wheel - Steering Lock Module)
• PAM (Parking Aid Module)
• EPS (Electric Power Steering Module.)
• HALF (Haptic Lane Feedback - Lane maintenance assistance module)
• ORC (Occupant Restraint Control)

The CAN-C2 is in the DLC multiple diagnosis connector.

The 120-ohm terminal resistors are in the ABS module and the ORC Airbag module.

CAN-BH 

The CAN-BH manages the data exchanged at medium speed between the electronic modules which manage the passenger compartment comfort on the vehicle.

The control units interconnected by the CAN-BH are:

• IPC (Instrument Panel Cluster)
• RRM (Radio Receiver Module)
• CSWM (Comfort Seat Wheel Module - Seat and Steering Wheel Heating Module)
• LBSS (Left Blind Spot Sensor)
• RBSS (Right Blind Spot Sensor)
• AMP (Amplifier - Hi-Fi system amplifier)
• HVAC (Heating Ventilation and Air Conditioning - Climate control module)
• BCM (Body Control Module)

The CAN-BH is in the DLC multiple diagnosis connector.

The 120-ohm terminal resistors are in the BCM and the IPC module.

LINs 

Some Modules dialogue with certain vehicle components via LINs. The BCM uses 4 LINs to dialogue with the following components:

• IBS (Intelligent Battery Sensor - negative battery terminal IBS)
• RLS (Rain Light Sensor - Rain sensor)

• SWS (Steering Wheel Switch bank)
• WCPM (Wireless Charging Pad Module - Wireless battery charger)
• ASBM (Auxiliary Switch Bank Module - controls on dashboard)
• ASBM2 (Auxiliary Switch Bank Module2 - controls on dashboard)
• RVCM (Rear View Camera Module)

• WSMP (Window Smart Motor Passenger)
• WSMD (Window Smart Motor Driver)

• CSWC (Cruise control Steering Wheel Commands)

There is a LIN line connecting the RFH module and the Run/Start starting button.
