Terrain Management

The Anti-Lock Brake System (ABS) module adjusts the vehicle dynamic system operational parameters when the terrain mode request message is received from the All Terrain Control Module (ATCM), depending on the terrain mode requested.

• Grass/Gravel/Snow - The base Anti-Lock Brake System (ABS), traction control and Electronic Stability Control (ESC) lower the threshold used to detect wheel lock up as it is more likely to occur on loose, slippery surfaces.
• Sand - The base Anti-Lock Brake System (ABS) raises the threshold used to detect wheel lock up to allow the vehicle to "dig into" sand or deep gravel surfaces. Traction control and Electronic Stability Control (ESC) raise the parameters for brake and engine torque reductions to optimize traction and engine performance.
• Mud/Ruts - The base Anti-Lock Brake System (ABS) lowers the threshold used to detect wheel lock up as it is more likely to occur on slippery, muddy surfaces. Traction control and Electronic Stability Control (ESC) raises the parameters for brake and engine torque reductions to optimize traction and engine performance.
