Communication And Networks: Communication

The vehicle features a bus architecture called Next-Generation Atlantis Architecture. Data transmission between the various modules in the Atlantis architecture occurs through the following digital networks:

• CAN-C (high-speed 500 kb/s)
• CAN-CH (high-speed 500 kb/s)
• CAN-IHS (medium-speed 125 kb/s)

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

CAN-C (CAN-C1) 2.9 V6 Quadrifoglio version with MT 

Modules on the CAN-C bus:

• Body Control Module (BCM)
• Instrument Panel Cluster (IPC)
• Occupant Restraint Control (ORC)
• Radio Frequency Hub (RFH) Module
• Antilock Brake System Module (ABS)
• Adaptive Cruise Control Module (ACC)
• Emergency Assistance Module (EAM)
• Primary Powertrain Control Module 2.9 V6 (PCM - P)
• Secondary Powertrain Control Module 2.9 V6 (PCM - S)
• Powertrain Control Module 2.0 I4 DI (PCM)

R041 - 120Ω network terminal resistor.

The CAN-C reaches the Data Link Connector (DLC) multiple diagnosis connector on pins 6 and 14.

The ACC module is connected to the Forward Facing Camera Module (FFCM) via a dedicated CAN-C line. The reason behind the dedicated data transmission line between the two modules is the continuous exchange of information between them during ACC and Forward Collision Warning (FCW) operation.

CAN-CH (CAN-C2) 

The baud rate of the CAN-CH is 500Kb/s (high speed).

The CAN-CH is used by chassis modules to exchange data:

• ABS Module
• BCM
• Electric Steering Lock (ESL)
• Park Assist Module (PAM)
• Electric Power Steering (EPS)
• FFCM - Haptic Lane Feedback (FFCM - HALF)
• Occupant Restraint Control (ORC)
• Active Aerodynamic Module Left - Front left Splitter actuator (AAML)
• Active Aerodynamic Module Right - Front right Splitter actuator (AAMR)
• Adaptive Front Light System (AFLS)
• Chassis Domain Control Module (CDCM)
• Torque Vectoring Module (TVM)

The CAN-CH is in the DLC multiple diagnosis connector. The CAN-CH reaches the DLC on pins 12 and 13

The 120Ω terminal resistors are in the ABS module and the ORC module.

CAN-IHS (CAN-BH) 

The baud rate of the CAN-IHS is 125Kb/s (medium speed).

The CAN-IHS is used by the following comfort control type of modules comfort:

• Instrument Panel Cluster (IPC)
• Comfort Seat Wheel Module (CSWM)
• Left Blind Spot Sensor (LBSS)
• Right Blind Spot Sensor (RBSS)
• Amplifier (AMP)
• Trailer Tow Module (TTM)
• Heating Ventilation and Air Conditioning (HVAC)
• Entertainment Telematic Module VP2, VP4 (ETM)
• BCM
• Entertainment Multimedia Control Module (EMCM)

The CAN-IHS is in the DLC.

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

LIN NETWORKS 

Certain electronic components on this vehicle have am integrated Local Interconnect Network (LIN) communication ability. These components will interface or communicate with their respective master modules. This interface is called LIN network data bus.

The BCM uses four LINs to communicate with the following components:

LIN1 

• Child Detection Module (CHDM)
• Intelligent Battery Sensor (IBS)
• Ultrasonic Anti-tilt Module (UAM)
• Alarm System Unit (ASU)
• Rain Light Sensor (RLS)

LIN2 

• Windshield Wiper Smart Motor (WWSM)
• Steering Wheel Switch (SWS) Bank
• Rear View Camera Module (RVCM)

LIN3 

• Window Smart Motor Passenger (WSMP)
• Window Smart Motor Driver (WSMD)
• Window Smart Motor Rear Left (WSMRL)
• Window Smart Moor Rear Right (WSMRR)
• Passenger Mirror Control Module (PMCM)
• Driver Mirror Control Module (DMCM)

LIN4 

• Cruise Control Steering Wheel Commands (CSWC)

The PCM communicates with the following components on the LIN bus network:

• Intelligent Alternator Module (IAM)
• Auxiliary Water Pump (AUW)

The AFLS module is the LIN master for:

• Left Headlamp Modules
• Right Headlamp Modules

The HVAC module is the LIN master for:

• Humidity Sensor (HUM)
• HVAC Control Panel Module (HCPM)

The EMCM is the LIN master for:

• Volume Control Knob
