Terrain Response Operation: Notes

The following vehicle subsystem control modules are used for the Terrain Response system:

• Engine management (engine control module)
• Transmission control (transmission control module - automatic transmission only)
• Transfer box control (transfer box control module)
• Rear differential control (rear differential control module - if fitted)
• Air suspension control (air suspension control module)
• Brake system (ABS/DSC/ETC/HDC functions) (ABS module)

Each subsystem operates in different ways in relation to the selected Terrain Response program to achieve the optimum traction, stability and ease of control for the terrain encountered. The system has a safety factor built in which ensures that any program can be safely used on any surface, even when an inappropriate program selection has been made.
