What NOT to do:
* Don't try to reset it using a simple fuse pull or battery disconnect. This might temporarily clear the light, but it won't fix the problem.
* Don't rely on generic OBD-II scanners. 1991 vehicles predate the standardized OBD-II system, so a standard OBD-II scanner won't be able to read the SRS codes.
What you SHOULD do:
1. Professional Diagnosis: The safest and most reliable method is to take your car to a qualified mechanic specializing in older vehicles or a Cadillac specialist. They have the proper diagnostic tools (often a scan tool specific to GM vehicles of that era) to read the SRS codes and pinpoint the exact problem. This could range from a faulty sensor to a wiring issue, a bad clock spring, or even a failing control module.
2. Repair the Underlying Problem: Once the mechanic identifies the problem, they'll repair it. This is crucial for safety. Ignoring the problem is extremely risky.
3. Professional Reset: After the repair, the mechanic will use their diagnostic tool to clear the SRS light. This confirms that the system is functioning correctly again.
Why simple resets don't work:
The SRS light isn't like a check engine light triggered by a minor issue. It indicates a potential safety hazard. The system stores diagnostic trouble codes (DTCs) which require specialized equipment to read and interpret. Simply clearing the light without fixing the root cause is highly irresponsible and dangerous.
In summary, prioritize safety. Get your Eldorado's airbag system professionally diagnosed and repaired before attempting any reset. The cost of repair is far less than the potential cost of injury or death.
