What Causes Auto Hold Failure?

[IslaAnn]

Auto hold failure is caused by a malfunction in the ABS pump. Below is an introduction to related content: 1. Auto Hold: The foreign term for auto hold is AUTO-HOLD, which refers to an automatic braking function. When this function is activated, such as when stopping at a traffic light, it eliminates the need to pull the handbrake, simplifying operations by avoiding the use of the handbrake or electronic parking brake. For automatic transmission models, it also reduces the need for frequent shifting between D to N or D to P. 2. Precautions: Regardless of the situation when parking, it is essential to develop the habit of pulling the handbrake lever tightly when leaving the vehicle. When using the handbrake, the lever must be pulled tightly; otherwise, it is easy to forget to release it when starting, which can lead to severe wear on the rear brake pads if the vehicle is forced to move.

Last week, the auto hold suddenly stopped working while I was driving, which gave me quite a scare at first. Later, I found out it's a common issue. Normally, it can hold the car on a slope by itself, but that time, pressing the button didn't work. I suspect there might be an issue with the brake sensor—either it's too dirty or there's poor contact in the wiring, which could interfere with the system. Additionally, if the car has just started or the battery is low, the system might go into self-protection mode and prevent the function from activating. I've also heard that software update bugs can cause such malfunctions, or accidentally pressing the settings button to turn off the function. Safety comes first when parking; after it failed, I immediately pulled the handbrake manually to prevent the car from rolling. During regular maintenance, remember to ask the mechanic to check the related circuits to avoid sudden accidents, especially during rainy or snowy weather when the risks are higher. If anything seems off, get it professionally checked right away.

There can be many reasons for auto-hold failure. My experience suggests starting with simple checks: see if any warning lights are illuminated on the dashboard, which may indicate sensor malfunctions, such as faulty brake or hill sensors causing signal loss. Aging electronic components could also be the culprit, like loose wiring or blown fuses in the control module, leading to signal interruption. External conditions matter too: if the vehicle is running but doors aren't properly closed or seatbelts aren't fastened, the system may automatically disable this function. From a safety perspective, failure might cause the car to roll on slopes, especially dangerous at intersections—it's advisable to develop a habit of checking function status before each start-up. For software conflicts, such as issues after a recent system update, try rebooting the infotainment system. For long-term use, consider getting a thorough inspection at authorized service centers every six months to prevent minor issues from escalating.

Automatic parking failure is usually caused by minor system malfunctions. I've encountered it twice, both due to sensor failures—either the brake or acceleration sensor was dirty or reported incorrect data, causing the system to disable the function. Software bugs are also common; errors in the control program can render the button ineffective. The feature may also fail to work when the vehicle is on a steep slope or when the battery voltage is unstable. For safety, if it fails, first use the foot brake or hand brake to stabilize the car, then check if a fuse has blown or try restarting the vehicle to see if the function can be restored. Regular maintenance, including cleaning sensors and updating software, can reduce the occurrence of such issues. Don't take it lightly—this feature is very useful for driving in congested cities, so get it fixed promptly if it breaks.
