How to Clear the Hill Start Assist Malfunction in Geely GL?
2 Answers
You can first turn off the hill start assist, wait 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: The formal name is 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 a maximum of about 2 seconds) applies braking to all four wheels to prevent the vehicle from rolling backward. 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 calmly. 2. Usage: With the vehicle's gear 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 point, the hill start assist system is activated (working time is two seconds), and the brake lights will illuminate to automatically generate braking.
My Emgrand GL also had this issue before. It turned out to be caused by interrupted ABS sensor signals. You can check a few simple things yourself first: find a safe flat road, turn the steering wheel fully to the left, squat down and inspect whether the right front wheel speed sensor has metal shavings stuck to it. Then turn off the engine, disconnect the negative battery terminal for ten minutes to reset the system. After restarting, shift to D gear and rev the engine to 3000 RPM for five seconds. I tried this method three times, and the trouble code really disappeared. If it still doesn't work, you'll have to visit the 4S shop. Their diagnostic tools read trouble codes very accurately. Last time they helped me reflash the hill start assist control module program, and it hasn't recurred for three years now. By the way, when washing your car, avoid blasting high-pressure water directly at the wheel hubs, as it can easily damage the sensors.
