When resetting their SRS airbag module, many people run into the issue of their airbag module not communicating properly. This can happen for a number of reasons. Read below to find out a few of those reasons.
One reason your SRS airbag module may not be communicating properly is because it is improperly grounded. This simply means that it needs to be bolted down completely in the reinstallation process. Believe it or not, this issue is pretty common.
Another reason may be because of the communication pins at the plug. To make sure this isn’t the reason you are having communication issues, make sure to inspect the communication pins where the harness connect into the front of the airbag module. Look out for any damage or corrosion present. Sometimes, the pins can push back, bend, or even break off.
A third cause of your airbag module not communicating may be because of problems with your scanner, and not the actual module itself. To scan your airbag module, make sure that the scanner you use is able to properly read the airbag diagnostic codes. The scanner should access your airbag system and support your vehicle make and model. A lot of scanners are just set to read the basic engine codes so you want to make sure yours is set to read your codes. Also, if you have a newer car you want to make sure you are not using an outdated scanning tool.
The wiring or harness can also be the reason for the issues you are having. Make sure to check that the harness or wiring surrounding the SRS airbag module isn’t cut or otherwise damaged anywhere.
If you determine that all the above issues aren’t the reason for your communication problems, you may want to send your SRS module to a professional company like Safety Restore.
