What Causes the Yellow Light to Flash on Roewe's One-Button Start?
2 Answers
Roewe's one-button start yellow light keeps flashing due to issues like poor wiring contact, battery depletion, key sensing problems, and steering wheel lock. The specific causes and solutions are as follows: Poor Wiring Contact: It might be caused by the installation of a dashcam or other electrical devices affecting the wiring contact, leading to the yellow light flashing. First, check the wiring and try reconnecting it. Battery Depletion: If the car battery is depleted, it may also cause issues with the one-button start. In this case, replacing the battery is a better option. Key Sensing Problem: If there is a strong magnetic field nearby, it can interfere with electronic devices, making it difficult to detect the key. You can point the key directly at the one-button start or quickly leave the area. Steering Wheel Lock: The steering wheel lock is a normal anti-theft feature. This situation occurs when the steering wheel is turned after the car is turned off, causing the car's computer to assume a theft attempt and automatically activate the anti-theft function. To resolve this, press the one-button start once, then step on the brake, turn the steering wheel, and press the one-button start again.
I noticed the yellow light flashing during the Roewe one-button start, which is a relatively common issue mostly caused by insufficient key fob battery. When the car fails to detect the key signal, the anti-theft system will illuminate the yellow warning light. Signal interference could also be a factor, such as having a phone too close in your pocket or other electronic devices emitting signals nearby. Additionally, if the vehicle's own battery voltage is slightly low, it may sometimes affect the recognition function of the starting system. Worse yet, the anti-theft module or the start button itself might be faulty, requiring professional equipment for detection and repair. I recommend first trying to replace the key fob battery—it's inexpensive and something you can do yourself. If that doesn’t work, check the vehicle battery to ensure there’s no corrosion. Finally, if the problem persists, avoid attempting DIY fixes and take it to a 4S shop for a comprehensive diagnosis, as ignoring it could lead to startup failure and leave you stranded on the road, compromising travel safety. Regular maintenance is the best preventive measure.
