    Icon920 No bus, air bag, check engine light

    just came on. Started with the airbag light a couple of weeks ago (off and on) and now the no bus, check engine and airbag came on. They went off after a few seconds. Jeep seems to run fine but just not sure what would be causing it. Connection maybe? We did have a lot of rain last night but the top was on. Any ideas? Thanks! BTW... 99 TJ 6 cyl.

    "No Bus" is usually a poor connection between the instrument cluster and the dash board, IIRC. You can usually remove the instrument cluster, clean the contacts, and slightly twist the contacts to make them a bit tighter of a connection when the the cluster is installed. Then, reinstall the cluster.

    Also, try searching for the term "no bus" for other causes and solutions.
