What happens when the hydraulic oil temperature drops to 200 degrees?

When the hydraulic oil temperature drops to 200 degrees, the SPNSN ERROR light turns off, indicating that the vehicle's systems are returning to normal operational parameters. This is critical as the SPNSN (Speed and Neutral Sensors) system relies on specific temperature ranges for optimal performance. When the hydraulic oil is too hot or too cold, it can trigger error lights and prevent proper functioning of the vehicle’s electronic systems, including vehicle speed regulation.

The reduction in temperature to a more manageable level signifies that the hydraulic fluid is now performing within the acceptable temperature range necessary for the seamless operation of various vehicle functions. This results in the deactivation of the SPNSN ERROR light, sending a signal that the system is now functioning properly and that the vehicle can resume regular operations.

In contrast, the other options do not directly relate to the hydraulic oil temperature being at 200 degrees or fail to adequately reflect the immediate consequence of that specific temperature drop. For instance, brake pressure normalization, vehicle speed resumption, and increase in ride height involve different mechanical and electronic systems that are not necessarily tied to the hydraulic oil temperature falling to that specific point.
