How to Deal with Hill Start Assist Malfunction in Geely GL?
2 Answers
You can first turn off the hill start assist, wait for a few minutes, and then restart it. If the malfunction persists, it is recommended to go to a 4S shop for maintenance and inspection. More information about hill start assist is as follows: 1. Introduction: Officially known as hill start assist. When the vehicle starts on a steep or slippery slope, the driver switches from the brake pedal to the accelerator pedal, and the vehicle may roll backward, making it difficult to start. To prevent this, the hill start assist control temporarily (for up to about 2 seconds) applies braking to all four wheels to prevent the vehicle from rolling back. Without hill start assist control, the driver must quickly and accurately switch from the brake pedal to the accelerator pedal. However, with hill start assist control, because it prevents the vehicle from rolling backward, the driver can easily start the vehicle and operate the pedals with ease. 2. Usage: When the vehicle's gear is in D (do not put it in P, other gears are acceptable), press the brake pedal firmly until you hear a "beep" sound. At this time, the hill start assist system is activated (working time is two seconds), and the brake lights will illuminate to automatically generate braking.
I was also confused when I first encountered the hill start assist malfunction. Later, I found out that this issue might be caused by several reasons. If the brake sensor or wheel speed sensor of the car is covered with mud, the system cannot detect the slope. Or, unstable battery voltage may cause the electronic control unit to malfunction. I suggest you try the following steps first: Park the car on a flat surface, turn off the engine, disconnect the negative terminal of the battery for 10 minutes, then reconnect it and restart the system. If the malfunction light on the dashboard is still on, check if the brake switch and wheel speed sensor have any obvious damage. Of course, the most important thing is not to force it, especially when starting on a steep slope—it's too dangerous if the car rolls back. Contact the 4S shop immediately to read the fault codes. They have specialized diagnostic tools to locate the problem, which might be that the hydraulic control unit needs to have its seals replaced.
