What is the reason for the hill start assist malfunction displayed on the Emgrand GL dashboard?
3 Answers
Emgrand GL dashboard displays hill start assist malfunction because the Emgrand GL comes with a hill start assist function, which prevents the vehicle from rolling back for three seconds when starting on a certain slope. The following is an introduction to the Emgrand GL hill start assist function: Introduction to the Emgrand GL hill start assist function: When the brake pedal is pressed to stop on a slope, the applied braking torque is sufficient to keep the vehicle stationary on the slope; when the vehicle is stationary, and the driver switches from pressing the brake pedal to pressing the accelerator pedal, the HHC maintains the braking pressure to ensure no rolling back; when the vehicle is still stationary, the HHC reduces the braking torque as the driving torque increases, ensuring the vehicle neither rolls back nor surges forward; when the driving torque is sufficient to move the vehicle forward, the HHC reduces the braking torque to zero, allowing the vehicle to start smoothly. Reasons for the Emgrand GL displaying hill start assist malfunction: The gear lever is not in the P position (for automatic transmission models) and the accelerator pedal is not pressed; the vehicle must also be stationary; the operator has not engaged the handbrake (foot brake or electronic brake). When these conditions are met, the hill start assist system will activate as the driver moves their foot from the brake pedal; in some vehicles, the hill start assist system automatically activates when the operator presses the brake pedal further. Additionally, this system also functions when reversing on a slope. Solutions for Emgrand GL hill start assist malfunction: First, you can try turning off the hill start assist, wait a few minutes, and then restart it. If the malfunction display persists, it is recommended to go to a 4S shop for maintenance and inspection.
I also encountered this issue while driving the Emgrand GL. The dashboard displaying a hill start assist fault is usually due to dirty or loose sensors, such as dust accumulation on the tilt sensor causing false alarms. Once when I was driving up a mountain, the system suddenly reported an error. Upon inspection, I found the undercarriage sensor was covered in mud, and it returned to normal after cleaning. It could also be an electronic control module bug or cable wear. I recommend first using an OBD scan tool to read the fault codes to confirm if it's a software issue. If you don't have the tool, simply check if the battery voltage is stable—too low voltage might disrupt the system. Don't ignore this warning; failure of hill start assist increases the risk of rolling back, especially in rain or snow. It's best to go to a 4S shop for a comprehensive inspection to ensure safety.
I often encounter this issue when repairing cars. The hill start assist malfunction in the Emgrand GL is mostly caused by poor sensor connections or control unit failures. It could be due to vehicle vibrations loosening the connectors or short circuits caused by aging wiring. Last time when I helped a neighbor check a similar car, we found oxidized module contacts after removing the dashboard panel, and it worked fine after cleaning the dust. Also, pay attention to the brake fluid level - if it's too low, it can affect the assist system's operation. It's best to inspect related components during regular maintenance and not wait until a major problem occurs. I suggest owners try turning the engine off and restarting first when encountering this issue, and if that doesn't work, send it for repair promptly.
