1. Reset SRS Warning Lights


Not every scan tool can effectively reset SRS warning lights.

However, Autel Maxilink ML629 is a great DIY scanner with an effective SRS feature.

When there is a problem with the airbag system, the SRS light will blink and stay on.

However, there is one major limitation of SRS warning lights.

It can only tell you that there is a problem with the airbag system but does not specify the problem’s exact source.

And this is where Autel Maxilink ML629 comes into play.

This scanner can help you to retrieve SRS Diagnostic Trouble Codes (DTCs).

The most common faults that affect the airbag system include damaged airbag, blown-up fuse, or defective airbag sensors.

Depending on the retrieved DTC, you can either replace the fuse or the sensors, which can be costly.

Even worse is when the airbag itself is damaged.

Replacing the airbag and the sensors is pretty expensive.

Once the repairs are made, you can use Autel Maxilink ML629 to reset the SRS lights.
