Here's what could be causing the flashing light:
* Faulty Airbag Control Module (ACM): This is the "brain" of the system and is a common culprit. It could be damaged internally or have a faulty connection.
* Faulty Airbag Sensor: These sensors detect impact and trigger the airbags. A damaged or malfunctioning sensor can cause the light to flash.
* Wiring Issues: Damaged, corroded, or loose wiring within the airbag system can interrupt signals and trigger the warning light. This is particularly common in older vehicles due to age and wear.
* Faulty Airbag: While less common, a faulty airbag itself could be the source of the problem.
* Clock Spring: This is a rotating electrical connector in the steering column that allows the airbag and other steering wheel components to move freely. A broken clock spring is a frequent cause of airbag light problems.
* Seatbelt Pretensioner Fault: These devices tighten seatbelts in a collision. A problem with them can also trigger the airbag light.
What you should NOT do:
* Ignore the light: This is extremely dangerous.
* Attempt to fix it yourself: The airbag system is complex and working on it incorrectly could result in injury or death. The system is under high pressure and must be handled by qualified professionals.
What you SHOULD do:
* Get it diagnosed by a qualified mechanic: A reputable mechanic with experience in automotive electrical systems, specifically airbag systems, should diagnose the problem using a diagnostic tool capable of reading airbag system codes. This will pinpoint the specific fault.
* Do not drive the car extensively until it's fixed: While you might be able to drive the car short distances, avoid long journeys or high-speed driving.
The cost of repair will vary considerably depending on the specific cause. A simple wiring issue might be relatively inexpensive to fix, while a faulty ACM or airbag could be significantly more costly. Getting a proper diagnosis is the first and most crucial step.
