How to Solve the Issue of Driver Airbag Resistance Being Too High?
2 Answers
Methods to address excessively high resistance in the driver airbag: 1. Check for open circuits: When poor wire harness connections cause an open circuit, the system will indicate excessively high resistance; 2. Use computer diagnostics: Employ a computer to read and determine which airbag has excessively high resistance, then inspect the corresponding wire harness connectors for looseness; 3. Inspect the airbag internals: Check if the airbag connector is loose. If it is secure and unobstructed, the issue likely lies within the main airbag; 4. Check the airbag clock spring: Examine the wiring beneath the airbag to determine if the clock spring is damaged; 5. Inspect the airbag module: If the fault code indicates excessive resistance in the airbag control unit, it is usually caused by an open circuit in the two wires of the airbag module. Damage to the airbag reset ring is more likely to cause resistance faults in the airbag module.
Speaking of high resistance in airbag circuits, I've seen plenty of that in my years in the auto repair business. The most common culprits are loose or corroded connectors, especially under the steering wheel. First, disconnect the battery negative terminal and wait 15 minutes to avoid electric shock. Then check if the connectors are clean and tight - try cleaning or reseating them. If resistance remains high, it could be a worn clock spring or faulty airbag module, which would need replacement. Don't attempt DIY disassembly - airbag accidental deployment is dangerous. I recommend professional diagnosis with a scan tool at a repair shop. High resistance may prevent proper airbag deployment during crashes with serious consequences, so get it fixed promptly. Remember to reset the system after repairs to ensure proper functionality.
