I have been working on some sort of electrical fault that was intermittently shutting my car off while driving and displaying a whole host of fault messages (Brake Failure, DTCS, Parking Brake, etc. etc. etc.) Progressively became worse to where the car wouldn't start at all... Performed multiple scans and got a few permanent faults tied to low signal and dozens of Loss Bus Comm faults (intermittent). Started by replacing accelerator pedal, then voltage regulator, had the CEM data pkg transferred to a donor, checked resistance on (+) (-) battery cables, performed voltage tests on new CEM... All are showing good.

So after installing new CEM, still got some recurring faults showing up. Disconnected power supply to CEM to reset (but forgot to disconnect ground at battery, duh) After reconnecting CEM, started to get SRS Service Urgent and Power Steering Service Required. From what I've read, this may be a result of not disconnecting the negative battery cable??? Anyways, I have a professional level diagnostic system (Autel 906TS). I've tried to access both the SRS and PS modules to reset and I am getting a "Can Not Communicate" message for both. Is this something that I need a VIDA Dice for??? Am I looking at having to go to dealer to have them reset both systems?

Thx for chiming in...
