OK the mystery has been solved. The software only could communicate with certain modules not the engine transmission or several other controllers. The engine would not turn over in the dashboard would scroll a brake error warning - drive to the nearest Service facility. I couldn't find an answer from anyone and the software couldn't communicate with the ECU or the brake module or transmission module. The shop couldn't figure it out and they sent me home and I had to have it towed to my garage. At least they didn't charge me. Someone said change your brake switch. In the end the problem was not a brake switch or starter or ECU or anything like that. It was simply relay 460 under the dashboard. I ordered an extra one and will keep it in the glove compartment. Car runs like a dream now!
