What does it mean when the airbag detonation device exceeds the upper limit?
2 Answers
Airbag detonation device exceeding the upper limit refers to a fault code indicating excessive resistance in the airbag control unit. Reasons for excessive resistance in airbags: Loose airbag connectors - If the wiring harness connector under the seat is loose, simply reconnect each one firmly. Damage to the clock spring (slip ring) in the steering column, or damage to the main airbag in the steering wheel. Side airbags are installed on the outer side of car seats and function to deploy during side impacts, protecting passengers from lateral collision forces. Definition of airbags: An airbag is a device that inflates to protect occupants before secondary impact occurs during a collision. As a supplemental restraint system (SRS) to seat belts, the airbag system consists of: an integrated airbag module containing the cushion and inflator (gas generator), impact sensors that detect collisions and trigger deployment, and wiring harnesses that transmit sensor signals.
I recently encountered a similar situation. While driving, a warning popped up on the dashboard indicating that the airbag detonation device exceeded the upper limit, which gave me a scare. After researching, I understood that this means the system detected an impact signal that was too large, exceeding the preset safety limit. Common causes include aging or short-circuiting sensors or abnormally high battery voltage. This could lead to accidental airbag deployment or failure to work, which would be extremely dangerous in the event of an accident. I immediately went to a repair shop, where the technician used a diagnostic tool to detect the issue and replaced the sensor, costing me a few hundred bucks. It's recommended to regularly maintain and check the sensor area to avoid dirt and dust buildup—don't wait until the warning appears to take action.
