How do you diagnose an airbag fault?
Most cars today can do an airbag diagnostic test. The test checks to see if all the sensors and circuits of the airbag are functioning. If the system detects any problems, it gives you a signal through the airbag indicator by flashing the light several times, giving you the specific problem the test has detected.
How much does an airbag diagnostic cost?
Expect to pay between $100 to $200 for the initial diagnostic. In this instance, look for reputation versus cost, so do not shop just on price. Many times a good shop will fold over some of the diagnostic into installation because they had to dig down to the component to test it.

What would cause the airbag light to come on?
The most common cause for the airbag light coming on is that the airbag system is deactivated or turned off. There may be an issue with the crash sensors or other airbag component. Alternatively, the sensor in the passenger seat that determines whether that airbag should be active or not may be faulty.

Can a diagnostic on the ECU clear the airbag?
A diagnostic on the ECU will not clear the airbag ECU. It has to be fully cleared in order for the airbag to be operational. When removing or installing an airbag ECU you should always remove the negative battery cable from the terminal first. After replacement, turn the key to accessories, then replace the cable.
What should I do if my airbag is not working?
The way to remedy this problem is to either clean the connectors or cut out the plugs and directly solder the wires together, repairing them one at a time so you do not mix up wires as quite often wiring colours can change as they pass through a multiplug.
Is the DLC connector used for airbag diagnostics?
If you think you have what you need to service and reset these systems, think again. Although the DLC connector has made most vehicle diagnostics uniform, the airbag systems are still outside that box. Also, the computer used for airbag codes is different from the computer used for the check engine light.
