The system determines when the gasoline engine operates and when electric propulsion is used. It also regulates battery charge and energy flow.
Transmission Control System
Gasoline models with a continuously variable transmission (CVT) use electronic transmission control.
Transmission Control Functions
- Ratio adjustment
- Throttle coordination
- Shift simulation control
- Torque converter management
Hybrid models with an electronic continuously variable transmission use integrated electronic management within the hybrid control unit.
Transmission control coordinates with the engine control module for smooth power delivery.
All-Wheel Drive Control System
CR-V models equipped with Real Time AWD with Intelligent Control System include a dedicated AWD control module.
AWD System Functions
- Torque distribution monitoring

The system transfers torque to the rear wheels when front-wheel slip is detected. It operates automatically through electronic management.
Vehicle Stability Assist System
The CR-V includes Vehicle Stability Assist (VSA).
VSA Control Elements
- Wheel speed sensors
- Yaw rate sensor
- Steering angle sensor
- Brake pressure modulation
The VSA computer adjusts braking force and engine output to maintain directional stability during traction loss.
Anti-Lock Braking System Module
The Anti-Lock Braking System (ABS) uses its own electronic control module.
ABS Functions
- Wheel speed monitoring
- Brake pressure modulation
- Skid prevention
ABS prevents wheel lock during emergency braking. The module communicates with VSA and traction control systems.
Honda Sensing System
The CR-V includes Honda Sensing driver assistance systems.
Honda Sensing Components
- Forward collision warning
- Collision mitigation braking system
- Lane departure warning
- Lane keeping assist system
- Adaptive cruise control
- Road departure mitigation
These systems rely on:
- Front-facing camera
- Radar sensor
The computer processes environmental data and adjusts braking or steering inputs when required.
Electric Power Steering Control Module
The CR-V uses electric power steering (EPS).
EPS Computer Functions
- Steering assist level adjustment
- Speed-sensitive assist control
- Lane keeping assist integration
The EPS control module varies steering assistance depending on vehicle speed and system input.
Airbag Control Unit
The Supplemental Restraint System (SRS) uses a dedicated control unit.
Airbag System Functions

The system processes user input and manages multimedia features.
Instrument Cluster Display System
The digital instrument display operates through a dedicated processing unit.
Display Functions
- Vehicle speed display
- Fuel level monitoring
- Hybrid energy flow display (hybrid trims)
- Warning message display
- Driver assistance status indicators
The cluster communicates with multiple control modules for real-time updates.
Climate Control Module
The automatic climate control system uses electronic regulation.
Climate Control Functions
- Temperature regulation
- Fan speed control
- Air distribution control
- Hybrid heat management integration
Sensors detect cabin temperature and adjust airflow accordingly.
Diagnostic Communication Network
All computer systems connect through a Controller Area Network (CAN bus).
Network Characteristics
- High-speed communication between modules
- Real-time data exchange
- Diagnostic capability
When a system fault occurs, the vehicle stores diagnostic trouble codes accessible through service equipment.
Security and Immobilizer System
The CR-V includes an electronic immobilizer.
Security Functions
- Key authentication
- Engine start authorization
- Theft deterrent control
The system prevents engine start unless a programmed key is detected.
Parking and Driver Assistance Modules
On equipped trims, the CR-V may include:
- Parking sensor control unit
- Blind spot information system module
- Cross traffic monitor module
These systems use ultrasonic or radar sensors for detection and warning.
Coordination Between Systems
Vehicle computer systems do not operate independently.
Integrated Communication
- ECM coordinates with transmission module
- Hybrid control system communicates with instrument cluster
- VSA interacts with AWD control module
- Honda Sensing integrates with EPS and braking systems
This integration ensures coordinated operation across the powertrain, safety, and driver-assistance systems.
