The EMS indicated that I should have my parking aid serviced, then the transmission. I parked up last night and this morning I can not get the Commander started - neither with jump crds or a booster pack - engine just keeps turning till no power at all.
This sounds like the bad shift selector module in the transmission, that was in another thread. I'm a Commander Newb, but knowledgeable on vehicle in general.
I don't know much about this failure, but saw another thread recently where someone was having problems starting, and getting fault codes for the Back-Up/Parking Asssit NOT working. Turned out to be the shift selector module for the electronic transmission that had to be replaced.
My guess, when the selector modules fails it sends all the interlocks for shifting in the transmission crazy, since the interlocks would tie through that module. i.e. the Back-Up/Park Assist system thinks you've shifted into reverse when your NOT, the ignition interlock to start the motor thinks your NOT in park and Neutral, when you are, and won't let the motor start.
Pure guess, but do a search for the thread, might be the problem.
Hopefully its under warranty, because I think the module and labor to replace it is expensive.
Maybe its us Yanks, getting back at the British for making cars with such unreliable electrical systems all these years. Joking, we love the Brits and love many of your cars, but we are warry of the reputation for electric problems.
