Why Does the Hill Descent Control System Malfunction?

[GenevieveAnn]

Hill descent control malfunction refers to the failure of the hill descent control function. Causes: It combines engine braking with the ABS anti-lock braking system to maintain a "low speed without losing tire grip" when the vehicle is descending a steep slope. Solutions for hill descent control malfunction: The brake fluid in the master cylinder reservoir decreases due to brake pad wear, triggering the fluid level indicator alarm. Solution: Top up the brake fluid to the appropriate level. Brake fluid leakage from the wheel cylinders or other parts of the braking system causes the fluid level in the master cylinder reservoir to drop too low, triggering the alarm. Solution: Locate and repair the leak, then refill the brake fluid to the proper level. When the vehicle is climbing a steep slope, the excessive incline may cause a false alarm from the fluid level indicator. This usually resolves automatically when the vehicle returns to level ground.
