:help: Has anybody had this code?  I did a search and nothing came up.
Any help would be greatly appreciated.
I know there are two impact sensors on the front are there any others I need to check?
 
Nope, but SIS= Side Impact Sensor
 
    ?  DTCs B0077 and B0078 will set when one of the following conditions occur:

      -  A valid ID message is not received within 5 seconds of the SIS being powered up.

      -  Status message is not received.

      -  The SDM has failed twice to reset the SIS.

The following can cause an intermittent condition:

    ?  A short between the SIS signal and voltage circuits

    ?  High or low resistance in the SIS signal and voltage circuits

    ?  Inspect the SIS signal and voltage circuits carefully for cutting and/or chafing

    ?  Verify that the correct SIS is installed in the vehicle
