I have the above recovered in with non start / No crank - only fault code that is accessible is in the BCM - B10A2 - Crash Input Circuits.

If I bridge the ignition relay all other modules have communication and all fault codes clear except the same in the PCM. Live data within the SRS shows no crash data / event.

Only diag tool I can find to list clearing the crash input is the Snap on but even this does not clear the DTC in the BCM - Is this a software issue or I am missing something please ?
