What are the reasons for the non-response of the GAC Trumpchi GS4 one-key start?
4 Answers
Here are the specific reasons for the non-response of the GAC Trumpchi GS4 one-key start: 1. Steering wheel lock: The steering wheel lock is an anti-theft feature. When the car is turned off, if the steering wheel is rotated a certain angle from the centered position in one direction, the steering wheel will lock. In the locked state, the one-key start function will not work. To release the tension and unlock the steering wheel, turn the steering wheel left and right while pressing the engine one-key start button. 2. Smart key battery dead: When the smart key's battery is dead, the key's transmission power is low, making it difficult for the car's sensor to detect the key. In this case, the one-key start cannot complete the ignition.
Last time I drove the Trumpchi GS4, I also encountered the one-button start not responding. After struggling for a while, I found out it was a key battery issue. Actually, there are quite a few possible reasons. First, check if the car key is out of battery or if there are any signal interferences nearby, like from a phone or power bank. Then, make sure the brake pedal is fully pressed—the system won’t recognize it if your foot isn’t firmly on the pedal. The gear also needs to be in P; even a slight misalignment won’t work. If the car battery is low, it’s even more troublesome—the dashboard lights will be very dim, or you might hear a clicking sound. Additionally, the start button itself might have poor contact and fail to work. Once, I couldn’t trigger it with wet hands. You can troubleshoot these situations yourself first, but if the problem persists, it’s best to go to the shop and have them read the fault codes with a computer.
I remember one time I was in a hurry and the start button didn't respond at all—I panicked! Later, I realized I made a rookie mistake—I didn't shift the gear back to P! Automatic transmission cars are particularly particular about this. Then there's the car key—keeping it in your pants pocket or with a bunch of metal keys can easily cause signal attenuation. Try placing it directly on the start button. Battery issues are common in winter, especially with older batteries over two years old. When the battery is low, even turning on the parking lights can be a struggle. If you confirm it's a remote key malfunction, there's usually a mechanical keyhole hidden under the steering wheel—insert the key and turn it halfway to start the car in an emergency. However, the electronic parking brake needs to be released manually, which might fluster beginners.
If the one-touch start fails, first check three key elements: key position, brake pedal depth, and gear status. Placing the key in the cup holder or on the center console is most reliable, as it might be shielded by metal objects in a bag. Pay attention to the pedal resistance when pressing the brake; if it feels too loose, the switch might be faulty. Check the battery level by observing the brightness of the dashboard—dim and yellow indicates low power. Finally, inspect if the floor mat is obstructing the brake lever. DIY solutions can resolve 80% of the issues, but module damage requires professional diagnostic equipment.
