Why is the seat belt warning sound not working for the front passenger seat in the Emgrand?
4 Answers
The reason why the seat belt warning sound is not working for the front passenger seat in the Emgrand: This vehicle is not equipped with a front passenger seat belt warning system, so there will be no alert if the front passenger seat belt is not fastened. Below are some precautions for using seat belts: 1. Regularly check the technical condition of the seat belts: If any damage is found, they should be replaced promptly. All bolts securing the seat belts on the floor near the seats should be tightened according to specifications, and sealant should be applied around the bolts. 2. Wear the seat belt correctly: The three-point lap belt should be worn as low as possible, around the hips, not the waist; the shoulder belt should not be placed under the arm but should cross the chest diagonally. Seat belts are for single-person use only; sharing a seat belt between two people is strictly prohibited. Do not twist the seat belt while using it.
I remember my car had an issue with the passenger seat belt warning sound before, don't panic yet. Most likely it's a poor connection in the weight sensor inside the seat, especially if people frequently get on and off, the sensor plug might be loose or dirty. The seat belt buckle switch could also be malfunctioning - try pressing the side contacts of the buckle with a small screwdriver to see if you hear a faint click. Wiring issues are also common, lift up the passenger foot mat to check if the yellow plug has come loose. Once I even encountered a case where the settings were accidentally turned off, so browse through the safety settings options on the center console screen. If all else fails, take it to the 4S shop to connect to the computer and read the fault codes - never try to dismantle the airbag wiring harness yourself as it can easily trigger error codes.
I've pondered this issue several times. Mainly need to check three areas: the seat weight sensor, the microswitch in the seatbelt buckle, and the buzzer circuit. First, record a video with your phone and test by sitting in the passenger seat to see if there's sound with or without the seatbelt, to rule out misjudgment. Then pry open the buckle to check if there are cookie crumbs stuck on the switch contacts. Next, get down and fiddle with the wiring harness under the seat - don't use brute force, try reconnecting it. For a simpler approach, just plug in an OBD scanner to check the fault records, which is better than blind guessing. The repair isn't too expensive, but it requires removing the seat trim panels - beginners shouldn't mess with it randomly.
The passenger seat alert not sounding is likely due to undetected occupant status. First, try pressing the center of the seat to see if the dashboard warning light illuminates. Then, repeatedly buckle and unbuckle the seatbelt a dozen times—the switch might have poor contact. Another possibility is a blown fuse in the alert module; check the 5A mini fuse labeled with a seat icon in the steering wheel fuse box. A colleague’s car had this issue last time—a dashcam installation caused a short circuit. If the cause remains unclear, visit a repair shop to have a mechanic test the buckle’s voltage continuity; the problem can usually be pinpointed within half an hour.
