Principles Of Operation: Notes

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

• Engine management - Engine Control Module (ECM)
• Transmission control - Transmission Control Module (TCM) (automatic transmission only)
• Active on-demand coupling control module
• Brake system - Anti-lock Brake System (ABS)/Dynamic Stability Control (DSC)/Electronic Traction Control (ETC)/ Hill Descent Control (HDC) - ABS module

Each sub-system 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.
