ive seen that message when starting up the commander but its really quick and you normally don't see it for that long to read all of it. try this trick to see if your throwing any codes.
I've got a 6 months warranty on this Jeep and that message can mean anything from (allegedly) a diagnostic, to failing battery, starter, alternator, gearbox/TC, solenoid pack, VSM (vehicle security modules) you name it and there may NOT be any DTC codes.
Its in the dealers interest to tell me its a diagnostic, instead of taking a hit on the rest on the expensive stuff, so that's why I need to know.
Nope! Even the Jeep tech said that should not happen. Once he'd cleared the codes it had gone, didn't take long to come back though, but hey the car seems to be running ok and I'm not out of warranty so I'm not too fussed.
